11. Select the best word for the blank in the following sentence: At the party, Fred asked ________ sister for a dance.

Answer: A

Explanation:

Fred asked his sister for a dance.

In this context, the appropriate word to fill in the blank is "his," as it indicates that the sister belongs to Fred.

A) his

This option is correct because it directly expresses possession, indicating that the sister being referred to is Fred's. The sentence becomes coherent and grammatically correct with this choice.

B) her

This option is incorrect as it suggests that Fred is asking someone else's sister to dance. The sentence would imply that he is seeking permission or a dance from a sister belonging to another individual, which does not align with the intended meaning.

C) my

This option is also incorrect because it implies that the speaker (Fred) is referring to his own sister in a possessive manner. However, the context suggests that he is the one asking, making "my" an inappropriate choice for the sentence structure.

D) their

This option is incorrect as it indicates a plural possessive form, suggesting that Fred is referring to a sister belonging to multiple people. The sentence does not support this plurality and requires a singular possessive term.

Conclusion

The choice "his" is definitively the right answer, as it maintains the singular possessive context necessary for the sentence to convey Fred asking his sister for a dance. All other options fail to provide the correct possessive form or misinterpret the ownership, leading to grammatical inaccuracies.
