Which prefix means 'between'?

• A. De-
• B. Inter-
• C. In-
• D. Bene-

Answer: (B)

The idea being tested is recognizing a prefix that conveys the sense of "between." The best choice is inter-, which comes from Latin for between or among and forms words that express a connection or position between two or more things: intercede means to go between people in a dispute, and an intersection is a point where lines meet between roads; international describes relations between nations, and intercity refers to connections between cities. The other prefixes don’t carry that sense: de- suggests removal or reversal, in- can mean into/inside or not depending on the context, and bene- means good or well. So inter- is the prefix that consistently means "between."
