Which choice completes the text so that it conforms to the conventions of Standard English?

A

sources, and then

B

sources and

C

sources; and

D

sources: and

Correct Answer: B

Choice B is the best answer. This question tests comma usage with compound predicates.

  1. Context clues: One subject ("scientist") performs two actions—compound predicate, not independent clauses.
  2. Meaning: Do NOT use a comma before "and" in a compound predicate (same subject).
  3. Verify: "The scientist collected data... and analyzed the results" is a compound predicate.

đź’ˇ Strategy: No comma before "and" when the same subject has two verbs (compound predicate).

Choice A is incorrect because a comma separates compound predicates incorrectly. Choice C is incorrect because a semicolon requires two independent clauses. Choice D is incorrect because a colon doesn't fit this structure.
