Understanding Word Formation from Letters

This question asks us to identify which word from the given options cannot be formed using only the letters available in the word "UNNECESSARILY". To solve this type of word formation problem, we need to count the occurrences of each letter in the original word and then check if the letters required for each option word are available in sufficient quantities.

Analyzing the Letters in UNNECESSARILY

Let's list the letters present in the word "UNNECESSARILY" and count how many times each appears:

The unique letters available are U, N, E, C, S, A, R, I, L, Y.

Checking Each Option for Word Formation

Now, we will examine each option word and see if its letters can be sourced from "UNNECESSARILY" based on the counts above.

Option 1: RAINY

The word RAINY requires the following letters:

• R: 1
• A: 1
• I: 1
• N: 1
• Y: 1

Checking against "UNNECESSARILY":

• R: We have 2 R's. We need 1. Available.
• A: We have 2 A's. We need 1. Available.
• I: We have 1 I. We need 1. Available.
• N: We have 2 N's. We need 1. Available.
• Y: We have 1 Y. We need 1. Available.

All letters required for RAINY are available in "UNNECESSARILY". Thus, RAINY can be formed.

Option 2: CRANE

The word CRANE requires the following letters:

• C: 1
• R: 1
• A: 1
• N: 1
• E: 1

Checking against "UNNECESSARILY":

• C: We have 1 C. We need 1. Available.
• R: We have 2 R's. We need 1. Available.
• A: We have 2 A's. We need 1. Available.
• N: We have 2 N's. We need 1. Available.
• E: We have 2 E's. We need 1. Available.

All letters required for CRANE are available in "UNNECESSARILY". Thus, CRANE can be formed.

Option 3: LUNAR

The word LUNAR requires the following letters:

• L: 1
• U: 1
• N: 1
• A: 1
• R: 1

Checking against "UNNECESSARILY":

• L: We have 1 L. We need 1. Available.
• U: We have 1 U. We need 1. Available.
• N: We have 2 N's. We need 1. Available.
• A: We have 2 A's. We need 1. Available.
• R: We have 2 R's. We need 1. Available.

All letters required for LUNAR are available in "UNNECESSARILY". Thus, LUNAR can be formed.

Option 4: CREATE

The word CREATE requires the following letters:

• C: 1
• R: 1
• E: 2
• A: 1
• T: 1

Checking against "UNNECESSARILY":

• C: We have 1 C. We need 1. Available.
• R: We have 2 R's. We need 1. Available.
• E: We have 2 E's. We need 2. Available.
• A: We have 2 A's. We need 1. Available.
• T: We have 0 T's. We need 1. Not Available.

The word CREATE requires the letter 'T', which is not present in the word "UNNECESSARILY". Therefore, CREATE cannot be formed using the letters of "UNNECESSARILY".

Conclusion on Word Formation

Based on our analysis of the letters available in "UNNECESSARILY", the word CREATE cannot be formed because it contains the letter 'T', which is not in the original word.

Additional Information on Letter Based Reasoning

Questions like this are common in reasoning and aptitude tests. They test your ability to carefully observe and compare sets of letters. Here are some tips:

• Always list the source word's letters and their counts first. This helps avoid errors, especially with repeated letters.
• Go through each option systematically.
• Check letter by letter for each option word against your list from the source word. Pay close attention to the required counts of letters.
• If even one letter is missing or required more times than available in the source word, that option word cannot be formed.
• This skill is related to anagrams, but here we are checking subset formation, not rearrangement of all letters.
