Question

read the definitions. ex- = \out\ im- = \in\ plicit = \folded\ which sentence uses the underlined word correctly? the research assignment came with explicit instructions on source citation. the speaker was explicit and difficult to understand. interpretations of the passage varied because its meaning was explicit. the custodian posted implicit instructions asking that the door remain locked.

Explanation:

Given the prefix "ex -" means "out" and "plicit" means "folded", "explicit" means unfolded or clear. The first sentence correctly uses "explicit" to mean clear instructions on source - citation. The second sentence wrongly says an explicit speaker is difficult to understand. The third sentence wrongly says a passage with explicit meaning has varied interpretations. For "implicit" (prefix "im -" means "in"), it means something not clearly stated, and the fourth sentence uses it wrongly as posted instructions are usually clear.

Answer:

The research assignment came with explicit instructions on source citation.
