Question 1

Classification – Odd one out (perfect squares) Three of the following numbers are perfect squares; one is not. Identify the non-square.

Accepted Answer

Introduction / Context:Recognizing squares rapidly is essential in many number-classification tasks. The goal is to isolate the single integer that is not equal to k^2 for any integer k.Given Data / Assumptions:Numbers: 1, 9, 16, 48We seek the non-square.Concept / Approach:Recall common squares: 1^2 = 1, 3^2 = 9, 4^2 = 16. Check 48 by bracketing between consecutive squares.Step-by-Step Solution:1 = 1^2 → square.9 = 3^2 → square.16 = 4^2 → square.48 lies between 6^2 = 36 and 7^2 = 49 → not a square.Verification / Alternative check:√48 ≈ 6.928… is non-integral, confirming non-square status.Why Other Options Are Wrong:1, 9, 16 → exact squares.None of these → there is one clear non-square (48).Common Pitfalls:Confusing “close to a square” with “is a square.” Only exact equality qualifies.Final Answer:48

Question 2

Classification – Odd one out (numeric pair rule) Each option is a pair a–b. Exactly one pair satisfies b = 2a. Identify the pair that follows doubling; it is the odd one out with respect to the others.

Accepted Answer

Introduction / Context:Pair-classification items often hide a simple arithmetic mapping from the first member to the second. Here we test for the doubling rule b = 2a. The skill is to check each option consistently and spot the single conforming (or non-conforming) case.Given Data / Assumptions:Pairs: 12–28, 14–82, 23–64, 36–72We examine whether b equals 2a.Concept / Approach:Compute 2a and compare to b in each pair. If exactly one pair matches, that pair is the odd one out relative to the rest (which do not match).Step-by-Step Solution:For 12–28: 2 * 12 = 24 ≠ 28 → no.For 14–82: 2 * 14 = 28 ≠ 82 → no.For 23–64: 2 * 23 = 46 ≠ 64 → no.For 36–72: 2 * 36 = 72 → yes (unique).Verification / Alternative check:If you try other plausible mappings (sum of digits, product, etc.), none yields a unique consistent rule across three choices. The clean doubling property isolates only 36–72.Why Other Options Are Wrong:12–28 → not double.14–82 → not double.23–64 → not double.None of these → one pair cleanly follows doubling (36–72).Common Pitfalls:Overfitting a complicated mapping to force matches on multiple pairs. The test favors a simple, uniquely identifying rule.Final Answer:36-72

Question 3

Classification – Odd one out (anagram category: flowers vs profession) Three strings are anagrams of flower names; one string is an anagram of a profession. Identify the odd one out.

Accepted Answer

Introduction / Context:Word-anagram classification relies on recognizing hidden base words. Here, three options unscramble to flower names, while one unscrambles to a profession. The mismatch in category (plant vs occupation) identifies the outlier.Given Data / Assumptions:DIRAMLOG → MARIGOLD (flower)UIHCSSBI → HIBISCUS (flower)AFOLDFID → DAFFODIL (flower)ERENIGEN → ENGINEER (profession)Concept / Approach:Attempt to unscramble each string into a familiar English word. Group them by semantic category and select the sole member from a different category.Step-by-Step Solution:DIRAMLOG → MARIGOLD → flower.UIHCSSBI → HIBISCUS → flower.AFOLDFID → DAFFODIL → flower.ERENIGEN → ENGINEER → profession → odd one out.Verification / Alternative check:Check letter counts to ensure perfect anagram matches (e.g., DAFFODIL contains exactly two Fs and two Ds present in AFOLDFID). This rules out near-misses.Why Other Options Are Wrong:DIRAMLOG → flower.UIHCSSBI → flower.AFOLDFID → flower.None of these → there is one non-flower anagram (ENGINEER).Common Pitfalls:Stopping after recognizing only one or two anagrams. Verify all to confirm category uniformity before selecting the odd one.Final Answer:ERENIGEN

Question 4

Classification – Odd one out (anagram category: vegetables vs household item) Three strings are anagrams of vegetable names; one is an anagram of a household item. Identify the odd one out.

Accepted Answer

Introduction / Context:Anagram classification by semantic field is a standard verbal reasoning theme. Spot the three vegetables and the single non-vegetable to answer correctly.Given Data / Assumptions:RARCTO → CARROT (vegetable)BACGEBA → CABBAGE (vegetable)ILBJARN → BRINJAL (eggplant; vegetable)NIATCRU → CURTAIN (household item)Concept / Approach:Unscramble each string into a common English word; then group by the “vegetable” semantic category.Step-by-Step Solution:RARCTO → CARROT → vegetable.BACGEBA → CABBAGE → vegetable.ILBJARN → BRINJAL → vegetable.NIATCRU → CURTAIN → household item → odd one out.Verification / Alternative check:Double-check all letters; each anagram must be a perfect rearrangement without additions/omissions. The category split is clear.Why Other Options Are Wrong:CARROT, CABBAGE, BRINJAL are vegetables.None of these → only NIATCRU is non-vegetable.Common Pitfalls:Mistaking “B R I N J A L” as non-standard; it is a common term for eggplant in many regions.Final Answer:NIATCRU

Question 5

Classification – Odd one out (anagram category: fruits vs vegetable) Three strings are anagrams of fruit names; one is an anagram of a vegetable. Identify the odd one out.

Accepted Answer

Introduction / Context:Here the majority category is “fruits” (APPLE, PAPAYA, GUAVA). The single outsider is a “vegetable.” Correct classification depends on recognizing all base words quickly.Given Data / Assumptions:LPAEP → APPLE (fruit)AYAPAP → PAPAYA (fruit)AVGAU → GUAVA (fruit)SRAHDI → RADISH (vegetable)Concept / Approach:Unscramble; then group by semantic field. The lone non-fruit is the answer.Step-by-Step Solution:APPLE → fruit.PAPAYA → fruit.GUAVA → fruit.RADISH → vegetable → odd one out.Verification / Alternative check:Check for letter multiplicities (e.g., PAPAYA has double A and P). The matches are exact.Why Other Options Are Wrong:LPAEP, AYAPAP, AVGAU → all fruits.None of these → there is exactly one vegetable anagram (SRAHDI).Common Pitfalls:Assuming GUAVA is misspelled; it is correct (G-U-A-V-A).Final Answer:SRAHDI

Question 6

Classification – Odd one out (bedding items vs adjective) Three anagrams resolve to bedding items; one resolves to a descriptive adjective. Identify the odd one out.

Accepted Answer

Introduction / Context:Anagram sets often hide three objects from one domain and a single intruder from another grammatical/semantic class. Here, PILLOW, MATTRESS, and QUILT are bedroom/bedding items; SOFTER is an adjective, not an item.Given Data / Assumptions:LIWLOP → PILLOW (bedding)RSTESMTA → MATTRESS (bedding)UTQLI → QUILT (bedding)TSROFE → SOFTER (adjective)Concept / Approach:Unscramble and categorize: object nouns vs adjectives. Select the non-object item.Step-by-Step Solution:PILLOW, MATTRESS, QUILT → physical bedding items.SOFTER → adjective → not a bedding item → odd one out.Verification / Alternative check:Try noun substitution in “Put the ___ on the bed.” Works for pillow/mattress/quilt, not for “softer.”Why Other Options Are Wrong:LIWLOP, RSTESMTA, UTQLI → resolve to bedding nouns.None of these → one clear adjective intruder (TSROFE).Common Pitfalls:Forcing “TSROFE” into “FOREST.” The exact letters rearrange to “SOFTER,” which is the intended mismatch.Final Answer:TSROFE

Question 7

Classification – Odd one out (geometry: dimension mismatch) In three pairs, the first term is a 2-D figure and the second is its standard sub-part or constituent (arc of a circle, angle of a polygon, line/side of a square). One pair mixes 1-D and 0-…

Accepted Answer

Introduction / Context:Geometric classifications often rely on consistent figure→sub-part relations within the same dimensional regime. Here, three entries pair a 2-D figure with a standard 1-D sub-feature (arc, side/line segment, angle as a constituent). The remaining pair is a 1-D object with a 0-D element, which breaks the pattern.Given Data / Assumptions:Circle : Arc → 2-D figure with a 1-D sub-part (arc on circumference)Hexagon : Angle → 2-D polygon with internal anglesSquare : Line → 2-D polygon with sides (line segments)Line : Dot → 1-D object with 0-D element (point)Concept / Approach:Group by the dimensional nature of the first term and the role of the second. Select the pair that does not maintain the “2-D figure → its canonical sub-part” pattern.Step-by-Step Solution:Circle : Arc → consistent.Hexagon : Angle → consistent.Square : Line → consistent (line segment/side).Line : Dot → dimensionally different; not a 2-D figure → odd.Verification / Alternative check:Attempt to phrase each as “part of the boundary or interior of the 2-D figure.” This phrasing works for circle/hexagon/square pairs, not for “line : dot.”Why Other Options Are Wrong:Circle : Arc → valid constituent relation.Hexagon : Angle → valid constituent relation.Square : Line → valid constituent relation.None of these → one clear dimensional mismatch exists (Line : Dot).Common Pitfalls:Over-generalizing “a line is made of points.” While true, the test’s intended uniformity is “2-D figure → standard sub-part,” which “line : dot” breaks.Final Answer:Line : Dot

Question 8

Classification – Odd one out (parts of speech) Among the following, three are verbs denoting actions; one is a noun. Identify the noun as the odd one out.

Accepted Answer

Introduction / Context:Parts-of-speech classification is a common verbal reasoning theme. The majority class here is action verbs; the single outsider is a noun naming a concept/state rather than an action.Given Data / Assumptions:Write (verb)Read (verb)Learn (verb)knowledge (noun; abstract)Concept / Approach:Label each word’s grammatical role. Choose the one that is not a verb.Step-by-Step Solution:Write → action verb.Read → action verb.Learn → action verb.knowledge → abstract noun → odd one out.Verification / Alternative check:Insertion test: “to ___” fits verbs (to write, to read, to learn) but not “to knowledge,” which is ungrammatical, confirming noun status.Why Other Options Are Wrong:Write, Read, Learn → verbs.None of these → exactly one noun exists (knowledge).Common Pitfalls:Capitalization or treating “knowledge” as proper. It is a common noun here; case does not change the part of speech.Final Answer:knowledge

Question 9

Classification – Odd one out (sharp/pointed objects vs blunt tool) Three of the following are typically sharp/pointed objects; one is a blunt striking tool. Identify the odd one out.

Accepted Answer

Introduction / Context:Physical-object classifications often contrast pointed/piercing items with blunt tools. Recognizing functional affordances (piercing vs striking) yields the answer quickly.Given Data / Assumptions:Screw → pointed tip for fasteningNeedle → pointed for piercingPin → pointed for fasteningHammer → blunt striking toolConcept / Approach:Group by typical function and tip shape: pointed vs blunt.Step-by-Step Solution:Screw → pointed.Needle → pointed.Pin → pointed.Hammer → blunt tool → odd one out.Verification / Alternative check:Consider usage verbs: pin/needle/screw pierce or thread; hammer strikes. The distinct action confirms the mismatch.Why Other Options Are Wrong:Screw, Needle, Pin → share “sharp/pointed” affordance.None of these → a single blunt tool exists (Hammer).Common Pitfalls:Overlooking that screws are indeed pointed at the tip in most common forms.Final Answer:Hammer

Question 10

Classification – Odd one out (form/length criterion) All four words relate to vertical direction/position, but one differs in form: it is the only two-letter word. Identify the odd one out by this consistent orthographic criterion.

Accepted Answer

Introduction / Context:When semantic categories fail to produce a unique outlier (here, all four relate to vertical orientation), classification questions often pivot to a clean formal criterion (length, morphology, capitalization). This prevents ambiguity from multiple valid semantic groupings (e.g., “Up/Down” as motion vs “Above/Below” as position).Given Data / Assumptions:Up (2 letters)Down (4 letters)Above (5 letters)Below (5 letters)Concept / Approach:Choose a crisp, unique formal property that isolates a single element without dispute. Word length is unambiguous and does not depend on context of use (adverb vs preposition).Step-by-Step Solution:Count letters of each option.Up → 2; Down → 4; Above → 5; Below → 5.Only “Up” has two letters → odd one out.Verification / Alternative check:Semantic partitions (motion vs position) yield two-and-two splits, not a unique outlier. Length criterion yields a single, objective outlier.Why Other Options Are Wrong:Down, Above, Below → length ≥ 4.None of these → one clear two-letter word exists (“Up”).Common Pitfalls:Trying to force a semantic singleton; with these four, semantics create pairs, not a unique odd element. Use the clean orthographic cue instead.Final Answer:Up

Question 11

Odd One Out — Among the diseases Tuberculosis, Smallpox, Cholera, and Typhoid, identify the one that does not belong to the same broad class of causative agents (bacterial vs viral) and justify your choice.

Accepted Answer

Introduction / Context:Classification items in verbal reasoning often rely on a shared scientific property. Here we consider whether each disease is primarily caused by a bacterium or a virus and use that distinction to isolate the outlier.Given Data / Assumptions:Tuberculosis: caused by Mycobacterium tuberculosis (bacterium).Cholera: caused by Vibrio cholerae (bacterium).Typhoid: caused by Salmonella Typhi (bacterium).Smallpox: caused by Variola virus (virus).Concept / Approach:Group items by causative agent. If three are bacterial diseases and one is viral, the viral disease is the odd one out.Step-by-Step Solution:Check Tuberculosis → bacterial.Check Cholera → bacterial.Check Typhoid → bacterial.Check Smallpox → viral.Therefore, Smallpox stands apart by etiology.Verification / Alternative check:Another check is eradication status: Smallpox was globally eradicated via vaccination; the other three remain public health concerns. This independent trait also singles out Smallpox.Why Other Options Are Wrong:Tuberculosis: bacterial; aligns with the majority.Cholera: bacterial; aligns with the majority.Typhoid: bacterial; aligns with the majority.Common Pitfalls:Confusing “prevalence” with classification. Even though smallpox is eradicated, its key distinguishing feature here is viral causation, not prevalence.Final Answer:Small pox

Question 12

Odd One Out — Tomato, Gourd, Brinjal (Eggplant), and Cucumber are all edible plant fruits; identify the one that uniquely ripens after harvest (climacteric) whereas the others are non-climacteric.

Accepted Answer

Introduction / Context:Many edible “vegetables” are botanically fruits. A subtle but important post-harvest trait distinguishes them: climacteric fruits continue ripening after harvest, while non-climacteric fruits do not. We will use this to find the outlier.Given Data / Assumptions:Tomato is climacteric (continues to ripen off the plant).Gourd is non-climacteric.Brinjal (eggplant) is generally treated as non-climacteric for storage/marketing.Cucumber is non-climacteric.Concept / Approach:Classify each item by post-harvest respiration/ethylene behavior and select the unique climacteric item.Step-by-Step Solution:Tomato → climacteric → can ripen further after harvest.Gourd → non-climacteric → minimal ripening off-vine.Brinjal → non-climacteric handling; quality declines post-harvest without ripening benefit.Cucumber → non-climacteric.Hence tomato is the lone climacteric item.Verification / Alternative check:Ethylene sensitivity also aligns: climacteric fruits respond strongly to ethylene for ripening; non-climacteric ones show limited ripening response.Why Other Options Are Wrong:Gourd: non-climacteric; matches the majority.Brinjal: non-climacteric behavior; matches the majority.Cucumber: non-climacteric; matches the majority.Common Pitfalls:Using family classification (Solanaceae vs Cucurbitaceae) leads to a 2–2 split, not a single outlier. The climacteric property yields a unique choice.Final Answer:Tomato

Question 13

Odd One Out — Pupil, Iris, and Cornea are parts of the human eye; Medulla is not. Identify the odd term and explain the anatomical distinction.

Accepted Answer

Introduction / Context:Anatomical grouping problems ask you to recognize which term does not belong to a stated organ system. Here three terms belong to the eye; one belongs to the brainstem.Given Data / Assumptions:Pupil: the variable opening in the iris controlling light entry.Iris: pigmented ring controlling pupil size.Cornea: transparent, outermost refractive surface of the eye.Medulla: medulla oblongata, part of the brainstem.Concept / Approach:Identify organ association for each term. If three map to the eye and one to the central nervous system, the latter is the outlier.Step-by-Step Solution:Map Pupil → Eye.Map Iris → Eye.Map Cornea → Eye.Map Medulla → Brainstem (not eye).Verification / Alternative check:Functional check: the first three govern light entry/refraction; the medulla regulates autonomic functions (breathing, heart rate), unrelated to ocular anatomy.Why Other Options Are Wrong:Pupil: ocular structure.Iris: ocular structure.Cornea: ocular structure.Common Pitfalls:Confusing “medulla” with “medulla of hair” or “renal medulla.” In common biomedical usage without qualifier, medulla refers to the brainstem region.Final Answer:Medulla

Question 14

Odd One Out — Hydrogen, Oxygen, and Nitrogen are diatomic gases at room temperature; Iodine is a solid halogen. Pick the odd term and justify.

Accepted Answer

Introduction / Context:Chemical classification can hinge on physical state and group behavior. Three listed elements are gaseous diatomic molecules at room conditions; one is a solid halogen.Given Data / Assumptions:Hydrogen (H2): diatomic gas.Oxygen (O2): diatomic gas.Nitrogen (N2): diatomic gas.Iodine (I2): solid at room temperature, subliming to a violet vapor on heating.Concept / Approach:Compare physical state under standard conditions (approximately 25°C, 1 atm). Select the only solid.Step-by-Step Solution:Hydrogen → gas.Oxygen → gas.Nitrogen → gas.Iodine → solid.Verification / Alternative check:Iodine also differs by group chemistry: it is a halogen (Group 17), while N2 and O2 are non-halogen p-block gases, and H2 is unique among elements but gaseous in state like N2 and O2.Why Other Options Are Wrong:Hydrogen, Oxygen, Nitrogen: share gaseous state at room temperature.Common Pitfalls:Assuming all halogens are gases at room temperature (only fluorine and chlorine are; bromine is liquid; iodine is solid).Final Answer:lodine

Question 15

Odd One Out — Sword, Knife, and Saw are primarily cutting implements; Shovel is primarily a digging/turning tool. Identify the odd one and explain.

Accepted Answer

Introduction / Context:Tool classification depends on principal function. Three items are designed to sever material; one is designed to move or loosen material rather than cut it.Given Data / Assumptions:Sword: edged weapon for cutting/slashing.Knife: edged utensil/tool for cutting.Saw: toothed cutting tool for wood/metal, etc.Shovel: scoop/spade for digging, lifting, and moving soil or aggregates.Concept / Approach:Group by function: cutting vs digging/handling.Step-by-Step Solution:Sword → cutting.Knife → cutting.Saw → cutting by abrasion/teeth.Shovel → digging/scooping, not primarily cutting.Verification / Alternative check:Edge geometry: the first three rely on sharp edges/teeth to separate material; a shovel’s leading edge is not intended for precise cut separation.Why Other Options Are Wrong:Sword: cutting implement.Knife: cutting implement.Saw: cutting implement.Common Pitfalls:Equating incidental slicing action while digging with a tool’s primary design; purpose dominates classification.Final Answer:Shovel

Question 16

Odd One Out — Collection, Cluster, and Assortment are neutral nouns meaning “group of items”; Compilation denotes the act/result of curating and editing materials. Pick the odd term.

Accepted Answer

Introduction / Context:Word classification problems often distinguish between a general label and a process/result term with editorial nuance. Three words simply denote “a group”; one implies deliberate gathering and editing.Given Data / Assumptions:Collection: set or group of things.Cluster: group of similar items positioned together.Assortment: variety/selection of different items.Compilation: a curated, edited gathering (e.g., a compilation album, compiled code/texts).Concept / Approach:Identify the word whose sense includes deliberate editorial/curation activity beyond mere grouping.Step-by-Step Solution:Collection → neutral group.Cluster → neutral group by proximity/similarity.Assortment → neutral group emphasizing variety.Compilation → curation/editing process/result; distinct.Verification / Alternative check:Usage in collocations: “compile data,” “compilation album” connote purposeful assembly; the others lack that editorial overtone.Why Other Options Are Wrong:Collection, Cluster, Assortment: generic group nouns without implied curation/editing.Common Pitfalls:Assuming “collection” implies curation; while a private collection can be curated, the word itself is neutral and does not require editorial transformation.Final Answer:Compilation

Question 17

Odd One Out — Mustard, Sesame, and Olive are primarily grown/used as oil-yielding crops; Corn is chiefly a cereal (monocot) grain. Identify the odd item.

Accepted Answer

Introduction / Context:Crop classification can consider primary agricultural purpose. Three items are classic oil sources; one is chiefly a cereal grain in agronomy and human diets.Given Data / Assumptions:Mustard: oilseed (edible mustard oil).Sesame: oilseed (sesame oil).Olive: fruit oil (olive oil).Corn (maize): cereal grain; although corn oil exists, the primary classification is cereal/food/feed.Concept / Approach:Choose by dominant agricultural category: oilseed/fruit-oil vs cereal grain.Step-by-Step Solution:Mustard → oilseed.Sesame → oilseed.Olive → oil-bearing fruit.Corn → cereal (monocot grass); not primarily categorized as an oil crop.Verification / Alternative check:Taxonomy: corn is a Poaceae monocot; mustard/sesame are dicots; olive is a dicot tree; monocot vs dicot distinction also isolates corn.Why Other Options Are Wrong:Mustard, Sesame, Olive: commonly grouped as oil-yielding crops.Common Pitfalls:Overemphasizing secondary products (e.g., corn oil) when the primary agronomic class is cereal grain.Final Answer:Corn

Question 18

Odd One Out — Iron, Potassium, and Sodium are metals; Chlorine is a non-metal halogen. Select the odd one and explain the grouping.

Accepted Answer

Introduction / Context:Chemical classification by metallic character is foundational. Three listed elements are metallic; one is a non-metal.Given Data / Assumptions:Iron (Fe): transition metal.Potassium (K): alkali metal.Sodium (Na): alkali metal.Chlorine (Cl): halogen, non-metal.Concept / Approach:Group by metallic vs non-metallic character.Step-by-Step Solution:Iron → metal.Potassium → metal.Sodium → metal.Chlorine → non-metal.Verification / Alternative check:State under standard conditions: Fe is solid metal; K and Na are soft reactive metals; Cl2 is a greenish gas—another differentiator.Why Other Options Are Wrong:Iron, Potassium, Sodium: all metals; they form cations in compounds.Common Pitfalls:Confusing high reactivity (K, Na) with “not metal”; reactivity does not negate metallic character.Final Answer:Chlorine

Question 19

Odd One Out — Wheat, Rice, and Barley are cereals (grasses); Pea is a legume (pulse). Identify the odd crop and justify.

Accepted Answer

Introduction / Context:Basic agricultural botany separates cereals (Poaceae grasses) from legumes (Fabaceae). Three options are cereals; one is a leguminous pulse.Given Data / Assumptions:Wheat, Rice, Barley: cereals (monocot grasses) grown for starchy grains.Pea: legume (dicot), valued for protein-rich seeds.Concept / Approach:Classify by plant family and primary macronutrient yield (starch vs protein) to identify the outlier.Step-by-Step Solution:Wheat → cereal.Rice → cereal.Barley → cereal.Pea → legume/pulse → outlier.Verification / Alternative check:Nitrogen fixation is common in legumes (root nodules), not cereals; this ecological trait further distinguishes pea.Why Other Options Are Wrong:Wheat, Rice, Barley: all cereals with similar agronomy and end-uses as staple grains.Common Pitfalls:Using “human staple” as a criterion—both cereals and pulses are staples; the family/nutrient class is the correct discriminator.Final Answer:Pea

Question 20

Odd One Out — Fish, Crab, and Octopus are aquatic animals without lungs; Crocodile is a reptile that breathes air with lungs and often lives amphibiously. Identify the odd one.

Accepted Answer

Introduction / Context:Zoological classification looks at taxonomy and respiration. Three organisms are aquatic forms that do not belong to the class Reptilia; one is a reptile with lungs and scales.Given Data / Assumptions:Fish: aquatic vertebrates using gills.Crab: aquatic/shore arthropod (crustacean); gills.Octopus: marine mollusk (cephalopod); gill breathing.Crocodile: reptile; lungs, scales/dermal armor; often amphibious lifestyle (water + land).Concept / Approach:Classify by major taxon and respiratory system. Select the lone reptile with pulmonary respiration.Step-by-Step Solution:Fish → non-reptile; gills.Crab → non-reptile; gills.Octopus → non-reptile; gills.Crocodile → reptile; lungs; distinct.Verification / Alternative check:Warm- vs cold-blooded does not neatly separate the set; taxonomy (Reptilia vs non-Reptilia) is cleaner and unique.Why Other Options Are Wrong:Fish, Crab, Octopus: none are reptiles; all primarily use gill respiration.Common Pitfalls:Grouping by “lives in water” alone leads to errors because crocodiles live in water but are still reptiles with lungs.Final Answer:Crocodile
