Jude appears to sometimes enjoy playing the devil's advocate.

Step 1: Analyze the question The sentence uses an idiom: "playing the devil's advocate." You are asked to choose the option that best explains its meaning.

Step 2: Explain the concept To play the devil's advocate means to argue against an idea or a popular opinion, even if you don't truly believe it. People do this to test how strong the argument is or to start a debate. It has nothing to do with acting as an actual devil or with playing a game.

The words "appears to sometimes enjoy" mean Jude seems to like doing this from time to time.

Step 3: Check each option

• A. Acting as the devil in films: Wrong. This takes the idiom literally, and the sentence says nothing about films.
• B. Playing the game: Wrong. "Playing" here is part of the idiom, not about a sport or game.
• C. Advancing the unpopular side of an argument: Correct. This matches the meaning of the idiom, which is taking up the opposing or unpopular position in a debate.
• D. Always enjoy appearing differently: Wrong. It does not mention arguing, and "always" contradicts "sometimes" in the sentence.

Step 4: Answer The correct option is C.

Exam tip: For idiom questions, never take the words literally. Ask yourself, "What does the whole phrase mean?" Also watch for absolute words like "always" in the options, because they often contradict qualifiers such as "sometimes" in the original sentence.
