VOCABULARY — Choose the best synonym (same meaning) of the highlighted word, based on the sentence. Sentence: “He found a LUCRATIVE assignment.”

Introduction / Context:
“Lucrative” describes something that yields substantial profit or monetary gain. In professional settings, a “lucrative assignment” is an engagement that pays well. Your task is to pick the synonym that specifically captures financial reward, not just general quality.

Given Data / Assumptions:

• The noun “assignment” suggests work or a project.
• The adjective focuses on financial return.
• We need a word that clearly signals profitability.

Concept / Approach:
“Profitable” directly denotes generating profit, aligning perfectly with “lucrative.” “Good” and “excellent” evaluate overall quality or satisfaction but do not necessarily imply high pay. “Significiant” is misspelled and even the correct “significant” would mean important, not profitable.

Step-by-Step Solution:
1) Extract target dimension: financial gain.2) Compare options: only “profitable” encodes money-making.3) Substitute: “a profitable assignment” preserves the intended meaning.4) Reject generic praise words and the misspelled distractor.

Verification / Alternative check:
Common collocations include “lucrative contract,” “lucrative market,” and “profitable venture,” showing clear overlap in usage.

Why Other Options Are Wrong:
A) “good” — vague; could be enjoyable or ethical.C) “excellent” — quality, not profit.D) “significiant” — misspelling; even “significant” ≠ profitable.

Common Pitfalls:
Equating positive evaluation with financial success. “Lucrative” is specifically about money.

Final Answer:
profitable
