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:

To determine the correct sentence, we analyze the meaning of "explicit" (clear, detailed, stated directly) and "implicit" (implied, not stated directly) using the prefixes: "ex-" means "out" (so explicit is clear/outward), "im-" means "in" (implicit is implied/inward).

• First option: "explicit instructions on source citation" makes sense (clear instructions).
• Second option: An explicit speaker should be easy to understand, not difficult.
• Third option: If meaning is explicit, interpretations should not vary (since it's clear).
• Fourth option: Instructions asking to lock the door should be explicit (stated), not implicit (implied).

Answer:

The research assignment came with explicit instructions on source citation.
