Arrange Ambitions, Ambiguous, Ambiguity, Animation and Animal in dictionary order and select the correct sequence.

Introduction / Context:
This question asks you to arrange five words in dictionary order: Ambitions, Ambiguous, Ambiguity, Animation and Animal. Three words share the “Ambig” prefix, while the other two start with “Ani”, so correct ordering requires careful comparison beyond the first few letters. Such questions are common in verbal reasoning and test your precision in alphabetical comparisons when words are closely related in spelling.

Given Data / Assumptions:
Index mapping:
1: Ambitions
2: Ambiguous
3: Ambiguity
4: Animation
5: Animal
Options like 3,2,1,5,4 represent proposed dictionary orders.
We assume standard dictionary rules, treating words strictly by letter sequence and placing shorter words first when one is an exact prefix of another.

Concept / Approach:
First, note that words starting with “Ambi” will come before words starting with “Ani” because b comes before n. Within the “Ambi” group, we compare Ambiguity, Ambiguous and Ambitions based on their remaining letters. Within the “Ani” group, we compare Animal and Animation. By ordering each group separately and then merging them, we obtain the full dictionary sequence.

Step-by-Step Solution:
Step 1: Separate by initial letters. Ambitions (1), Ambiguous (2) and Ambiguity (3) start with “Ambi”. Animation (4) and Animal (5) start with “Ani”. Because b precedes n, all “Ambi” words must appear before any “Ani” word. Step 2: Order the “Ambi” words. Ambiguous: a m b i g u o u s. Ambiguity: a m b i g u i t y. Ambitions: a m b i t i o n s. After the shared “Ambi”, compare the fifth letter. For Ambiguous and Ambiguity, the fifth letter is g; for Ambitions, it is t. Since g comes before t, both Ambiguity and Ambiguous come before Ambitions. Now compare Ambiguity and Ambiguous more closely. Ambiguity: a m b i g u i t y. Ambiguous: a m b i g u o u s. After “Ambigu”, Ambiguity has “i” as the next letter, while Ambiguous has “o”. Since i comes before o, Ambiguity (3) comes before Ambiguous (2). Therefore the order within the “Ambi” group is: Ambiguity (3), Ambiguous (2), Ambitions (1). Step 3: Order Animal (5) and Animation (4). Both begin with “Ani”. Animal is a n i m a l; Animation is a n i m a t i o n. Animal is a prefix of Animation, so the shorter word Animal (5) comes before Animation (4). Step 4: Combine all positions. First the “Ambi” words: 3, 2, 1. Then the “Ani” words: 5, 4. Final dictionary order: Ambiguity (3), Ambiguous (2), Ambitions (1), Animal (5), Animation (4). This corresponds to 3,2,1,5,4.

Verification / Alternative check:
Listing the words in this order, we get Ambiguity, Ambiguous, Ambitions, Animal, Animation. The transition from Ambiguity to Ambiguous is justified because i after “Ambigu” precedes o. Ambitions comes later because its fifth letter t is alphabetically after g. For Animal and Animation, the former is a strict prefix, so it must appear first. No alternative option reproduces this entire order, confirming that 3,2,1,5,4 is correct.

Why Other Options Are Wrong:
Any option that places an “Ani” word before any “Ambi” word ignores that b is before n in the alphabet.
Options that reverse Ambiguous and Ambiguity fail to consider the i versus o comparison after the shared “Ambigu” segment.
Sequences that put Animation before Animal do not apply the rule that a shorter word with the same starting sequence precedes its longer extension.
Therefore only 3,2,1,5,4 is fully consistent with dictionary ordering rules.

Common Pitfalls:
Because Ambiguity and Ambiguous are very similar, many candidates rely on intuition rather than checking the inner letters carefully. Likewise, they may focus on the overall sound of Animal and Animation rather than noting that Animal is a strict prefix. To avoid such mistakes, always write the words clearly, mark the first different letter in each pair, and compare those letters in isolation according to the alphabet.

Final Answer:
The correct dictionary order is Ambiguity, Ambiguous, Ambitions, Animal, Animation, corresponding to the sequence 3, 2, 1, 5, 4.
