Choose the correct response. There's ... coffee in the pot.

Solution:

The sentence "There's ... coffee in the pot." implies a quantity of coffee. 'Coffee' is a non-count noun. Therefore, the correct quantifier is 'plenty of'. 'Many' is used for count nouns, and 'few' implies a small, insufficient amount, which is not suggested by the sentence structure.

1. 'plenty of' - Used with non-count nouns to indicate a large amount.
2. 'many' - Used with count nouns.
3. 'few' - Used with count nouns to indicate a small amount.

Answer: a. plenty of
