Choose the correct answer. Has she got ___ pasta?

The question is a negative interrogative sentence. In such sentences, 'any' is typically used to ask about the existence of something, especially when it's not expected or when the speaker is unsure. 'Some' is generally used in affirmative sentences or in questions where the speaker expects a positive answer. 'An' and 'a' are used before singular countable nouns. Since 'pasta' is an uncountable noun, 'an' and 'a' are incorrect. Therefore, 'any' is the most appropriate choice.

The correct answer is any.
