Word formation using specific letters From the word "TECHNOLOGY", use its 1st, 2nd, 3rd, and 5th letters only to form a meaningful English word. If exactly one such word exists, what is the 3rd letter of that word? (If no word can be formed, answer "X"; if more than one word can be formed, answer "Y".)

Introduction / Context:
This verbal-reasoning task asks you to isolate specific letters from a longer word and determine whether they can form exactly one standard English word. The focus is on careful position picking and checking uniqueness of the formed word. The question finally asks for the third letter of that uniquely determined word, or instructs to choose special placeholders if zero or multiple valid words exist.

Given Data / Assumptions:

• Base word: TECHNOLOGY.
• Required positions: 1st, 2nd, 3rd, and 5th letters.
• Special rules: If no word is possible → X; if more than one word is possible → Y; otherwise, report the third letter of the unique word.

Concept / Approach:
Extract the specified letters and consider all permutations that form standard English words. We must verify uniqueness to decide whether to output a letter or X/Y. The exercise trains precision in indexing and elimination of near matches that are not valid dictionary words.

Step-by-Step Solution:
1) Write TECHNOLOGY with indices: 1 T, 2 E, 3 C, 4 H, 5 N, 6 O, 7 L, 8 O, 9 G, 10 Y.2) Pick letters at 1,2,3,5 → {T, E, C, N}.3) Check meaningful anagrams: "CENT" is a valid English word; alternatives like "CNET", "ETCN", "TENC" are invalid.4) Uniqueness holds since only "CENT" qualifies.5) The third letter of "CENT" is N.

Verification / Alternative check:
Confirm that none of the other permutations (e.g., TENC, ENCT, CNTE) are recognized as standard English words in general vocabulary use. This preserves the uniqueness condition.

Why Other Options Are Wrong:

• C and T: These would be the first or fourth letters in plausible sequences; they are not the third letter of the unique valid word.
• X: Not applicable since at least one valid word exists.

Common Pitfalls:
Forgetting to index correctly (off-by-one errors), accepting abbreviations or names as valid words, or overlooking the uniqueness criterion.

Final Answer:
N
