Arrange the following “Che…” words in correct alphabetical (dictionary) order: 1) Chemistry 2) Chamber 3) Cheap 4) Cheerful Choose the correct ascending sequence.

Introduction / Context:
When several words share initial letters, alphabetical ordering depends on the first position where they differ. Here, all begin with “Ch…”, so we must compare subsequent letters carefully and follow standard dictionary rules.

Given Data / Assumptions:

• Words: Chamber, Cheap, Cheerful, Chemistry.
• Alphabetical comparison is lexicographic (left to right).

Concept / Approach:
Break ties progressively: compare third letter, then fourth, etc. If one word is a prefix of another, the shorter word comes first, but here none is a strict prefix of another.

Step-by-Step Solution:
“Chamber” (Cham…) vs others that start “Che…”. Since “a” < “e”, Chamber comes first.Among “Che…” words: compare the next letters.“Cheap” (Chea…) vs “Cheerful” (Chee…): “a” (97) < “e” (101), so Cheap precedes Cheerful.“Chemistry” (Chem…) follows Cheerful because “m” comes after “e”.Final order: Chamber → Cheap → Cheerful → Chemistry → indices 2, 3, 4, 1.

Verification / Alternative check:
Write the four words and mark the first index where letters differ; confirm the relative order by ASCII/letter sequence.

Why Other Options Are Wrong:

• 2, 1, 3, 4: places Chemistry before Cheap/Cheerful incorrectly.
• 3, 4, 2, 1 or 2, 4, 3, 1: misorder the “Che…” group.
• None of these: Not applicable as a correct sequence is present.

Common Pitfalls:
Judging only by the third letter and forgetting to continue comparisons when initial segments match.

Final Answer:
2, 3, 4, 1
