David picked up . . . . . . . . nut from . . . . . . . . hole. A. the, the B. a, an C. a, the D. the, a

The correct answer is: B. a, an

The word “nut” is a common noun, which means that it can refer to any nut. In this case, we don’t know which specific nut David picked up, so we use the indefinite article “a”. The word “hole” is also a common noun, but it is not specific enough to warrant the use of the definite article “the”. For example, if David had said “I picked up the nut from the hole in the tree”, then we would know which specific hole he was referring to. However, since he did not say that, we can only assume that he picked up a nut from any old hole.

Here is a more detailed explanation of each option:

• A. the, the
  This option is incorrect because it uses the definite article “the” twice. The definite article is used to refer to specific people, places, or things. In this case, we don’t know which specific nut David picked up, so we cannot use the definite article.
• B. a, an
  This option is correct because it uses the indefinite article “a” once and the indefinite article “an” once. The indefinite article is used to refer to general people, places, or things. In this case, we don’t know which specific nut David picked up, so we use the indefinite article “a”. The word “hole” is also a common noun, but it is not specific enough to warrant the use of the definite article “the”.
• C. a, the
  This option is incorrect because it uses the indefinite article “a” once and the definite article “the” once. The definite article is used to refer to specific people, places, or things. In this case, we don’t know which specific nut David picked up, so we cannot use the definite article.
• D. the, a
  This option is incorrect because it uses the definite article “the” twice. The definite article is used to refer to specific people, places, or things. In this case, we don’t know which specific nut David picked up, so we cannot use the definite article.
