Explanation:

Question 1

To solve this, we analyze the meaning of "challenge" and the options:

• "question" can be a synonym (as in questioning/challenging), "believe" is an antonym (opposite of challenging), "compete with" is also a synonym (challenging in a competitive sense). But typically, "question" is a closer synonym for challenging in the context of challenging an authority. So:
• Synonym (S): a. question
• Antonym (A): b. believe
• Another synonym (if we consider the third category, maybe related term): c. compete with (but the main synonym here is a, antonym is b)

"Findings" means the results of research.

• "beginnings" is not related, "results" is a synonym, "accidentally discover" is a verb phrase, not a synonym for "findings" (a noun). So:
• Synonym (S): b. results
• Antonym (not really an antonym here, but the other options: a. beginnings is unrelated, c. is a verb). So S: b, others: a (unrelated), c (verb, not synonym)

"Glinting" means reflecting light, shining.

• "looking quickly" is about the action of looking, not the light reflection. "dull; darkening" is an antonym (opposite of glinting). "reflecting; shining" is a synonym. So:
• Synonym (S): c. reflecting; shining
• Antonym (A): b. dull; darkening
• Unrelated: a. looking quickly

Answer:

For "challenge":
S: a. question
A: b. believe
(Third: c. compete with)
