12. Which of the following words is the best close-up word? A. Vegetable B. Plant C. Zucchini D. Food

I'm not entirely sure what a "close-up" word is, but I am assuming that it means the most descriptive.

In this case, the word would be zucchini, because it is the most specific word given. Vegetable, plant, and food all refer to a wide variety of different things, whereas zucchini is very specific.

C. Zucchini is the best close-up word.
