After the following sentence, a list of possible interpretations is given. Choose the interpretaion that is…

Analyze the question: The sentence uses an idiom, "get along like a house on fire." You are asked to choose the meaning that fits it best.

Explain the concept: An idiom's meaning is not found in its individual words. Taken literally, "a house on fire" sounds destructive. But the idiom "to get along (or get on) like a house on fire" means to become friends very quickly and have a warm, close, harmonious relationship. The image is of how fast a fire spreads, so the friendship develops rapidly and intensely.

Step-by-step solution:

1. Identify the idiom: "get along like a house on fire."
2. Recall its meaning: to get on extremely well with someone.
3. Check each option: • A. have a very good relationship: matches the idiom. • B. are not on speaking terms: this means they are quarrelling, which is the opposite. • C. avoid each other always: also the opposite. • D. pretend to like each other: this suggests insincerity, which the idiom does not imply.

Answer: Peter and Paul have a very good relationship, so the correct option is A.

Tip: In idiom questions, do not be misled by frightening or negative-sounding words like "fire." Ask yourself whether the idiom is positive or negative overall. Here "get along" signals a positive relationship, which quickly eliminates B, C and D.
