Question

read the passage. then, select the antonym of the word in bold. i was hoping that professor finleys physics lecture would clarify string theory for me. instead, her discussion of quarks, leptons, muons, and gluons only served to obfuscate the concept. i wish shed remembered that she was dealing with a lay audience.

Explanation:

The word "obfuscate" means to make something unclear or confused. The opposite is to make something clear. In the passage, the person hoped the lecture would "clarify" (make clear), so the antonym of "obfuscate" is "clarify".

Answer:

clarify
