The question asks for the statement that must be true on the basis of the passage, so this is an Inference question.
An inference is a conclusion reached by valid reasoning on the basis of evidence. In other words, an inference must be true based on the facts.
Therefore, begin to answer this question by getting clear on the facts:
Every delegate is a party member.
Some delegates are government officials.
Each (every) government official is a speaker.
Look for the answer that must be true on the basis of these facts.
Choice A: While every delegate is a party member, it isn't necessarily true that every party member is a delegate. There may be party members at the convention who aren't delegates, so eliminate choice A.
Choice B: While every government official is a speaker, it isn't necessarily true that some speakers are neither party members nor delegates. It might be the case that every speaker is either a delegate or a party member, so eliminate choice B.
Choice C: Some delegates are government officials, and every government official is a speaker. Since delegates who are government officials speak at the convention, at least one of the speakers must be a delegate. On the basis of the facts, this statement must be true, so keep choice C.
Choice D: While every government official is a speaker, it isn't necessarily true that all speakers are government officials. There may be speakers who aren't government officials, so eliminate choice D.
Choice E: While some delegates are government officials, it isn't necessarily true that all government officials are delegates. Thus, while every delegate is a party member, there may be government officials at the convention who aren't delegates, and those government officials needn't be party members. Eliminate choice E.
The correct answer is choice
C.
