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:

1. First, break down the words using the given roots:

• Explicit: "ex-" (out) + "plicit" (folded) = unfolded, clear, direct.
• Implicit: "im-" (in) + "plicit" (folded) = folded in, implied, not direct.

1. Analyze each option:

• Option 1: "Explicit instructions on source citation" makes sense, as clear, direct instructions match the definition of explicit.
• Option 2: If a speaker is "explicit", they would be easy to understand, not difficult. This is incorrect.
• Option 3: If a passage's meaning is "explicit", interpretations would not vary. This is incorrect.
• Option 4: "Implicit instructions asking that the door remain locked" is contradictory, because direct instructions to lock a door are explicit, not implied. This is incorrect.

Answer:

The research assignment came with explicit instructions on source citation.
