Difficulty: Easy
Correct Answer: Globe
Explanation:
Introduction / Context:
This is a word formation question based on the word "Biological". You must determine which of the given words cannot be formed using the letters of "Biological", with each letter used at most once. Such questions test your ability to count letters and compare letter requirements between a base word and candidate words.
Given Data / Assumptions:
Concept / Approach:
To decide whether a given word can be formed, we break it into letters and compare the number of each letter required with the number available in the base word. If any required letter is not present in the base word, or is required more times than available, then that candidate word cannot be formed. Otherwise, it is a valid formation.
Step-by-Step Solution:
Step 1: List the available letters and their counts from "Biological": B 1, I 2, O 2, L 2, G 1, C 1, A 1.
Step 2: Check "Logic". It consists of L, O, G, I, C. Each of these letters appears in the base word and none is required more than once. So "Logic" can be formed.
Step 3: Check "Globe". It consists of G, L, O, B, E. G, L, O, and B are present in "Biological", but the letter E does not occur at all in the base word.
Step 4: Because E is completely absent, "Globe" cannot be formed from the letters of "Biological".
Step 5: Check "Bail". Letters are B, A, I, L. Each appears in the base word, with B 1, A 1, I 2, L 2 available, so "Bail" can be formed.
Step 6: Check "Bill". Letters are B, I, L, L. The base word has B 1, I 2, and L 2, so "Bill" is also formable.
Step 7: Check "Local". Letters are L, O, C, A, L. All appear in "Biological" with sufficient counts (L 2, O 2, C 1, A 1), so "Local" can be formed as well.
Verification / Alternative check:
We can summarise: the only suspect letter across options is E in "Globe". Since E does not appear in "Biological" even once, no rearrangement of the base letters can produce a word containing E. All other options are made solely from letters that are present and do not exceed the available counts, so they are valid formations.
Why Other Options Are Wrong:
"Logic" uses L, O, G, I, C, all of which are available. "Bail" uses B, A, I, L, again all present with enough frequency. "Bill" uses B, I, L, L and is also supported by the letter distribution. "Local" uses L twice and O, C, A once each, which fits perfectly. These words therefore can be formed and are not the correct answer to the question.
Common Pitfalls:
Some candidates quickly scan and mark the longest word or the one that looks most complex, instead of actually checking letter counts. Others overlook repeated letters and do not verify whether the base word has enough copies. The safest method is always to count the occurrences in both the base word and each candidate word, even if the word looks simple.
Final Answer:
The word that cannot be formed from "Biological" is Globe.
