Difficulty: MediumMultiple-Meaning Words

Fill in each blank with the same vocabulary word to satisfy the distinct meaning required by each sentence.

Answer:1. The research team developed a synthetic chemical 【compound】 to protect the aircraft fuselage from corrosion.
2. Neglecting routine maintenance will only 【compound】 mechanical problems and lead to premature engine failure.

Answer

The word "compound" correctly completes both sentences.
The polysemous word "compound" functions correctly in both sentences. In the first sentence, it operates as a noun naming a substance composed of united elements. In the second sentence, it operates as a transitive verb meaning to aggravate, intensify, or make an existing problem more severe.

Analyze the context and part of speech required for the second sentence.
The second sentence requires a verb meaning to make something worse, intensify, or add to existing complications.
The sentence describes how deferred maintenance exacerbates mechanical problems.
3
Identify the common lemma that satisfies both distinct definitions.
"Compound" functions as a noun (a chemical substance) and as a verb (to aggravate or intensify).
Choosing "compound" aligns with both semantic and grammatical requirements.
