Question

once in a blue moon, my dad goes to the city. when he is there, he is ______. an arm and a leg like a fish out of water the tip of the iceberg

Explanation:

We need to choose the correct idiom to complete the sentence. "Once in a blue moon" means something happens very rarely. Now let's analyze each option:

• "an arm and a leg" means something is very expensive. This doesn't fit the context of how the dad is when in the city.
• "like a fish out of water" means someone is uncomfortable or out of place in a particular situation. If the dad rarely goes to the city, he might feel out of place there, which makes sense.
• "the tip of the iceberg" means a small part of a much larger problem or situation. This is not relevant to how the dad is in the city.

Answer:

B. like a fish out of water
