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:

• Analyze each option based on the given prefix and root - word meanings.
• For "explicit", with "ex - = out" and "plicit = folded", it means clearly expressed.
• Option 1: "The research assignment came with explicit instructions on source citation." - Instructions that are clearly laid out (out - folded, i.e., clear) makes sense.
• Option 2: "The speaker was explicit and difficult to understand." - If something is explicit, it should be easy to understand, not difficult.
• Option 3: "Interpretations of the passage varied because its meaning was explicit." - If the meaning was explicit (clear), there would not be varied interpretations.
• Option 4: "The custodian posted implicit instructions asking that the door remain locked." - The prefix here should be related to the correct word. Since we are looking at "explicit" usage, and "implicit" has a different prefix ("im - = in"), this is about a wrong - word usage (even if the sentence logic is off for another reason).

Answer:

The research assignment came with explicit instructions on source citation.
