Question 9

Changing the comma to a period in sentence 4 corrects the error in the excerpt.

By changing the comma to a period in sentence 4, the sentence structure is improved, making it clearer and more grammatically correct.

A) Changing the exclamation point to a period in sentence 1

This option does not correct an error because sentence 1’s exclamation point may be appropriate, depending on the intended tone. If the sentence is meant to convey excitement or emphasis, retaining the exclamation point is correct. Therefore, this change does not address a grammatical error.

B) Adding a comma after 'day' in sentence 3

Adding a comma after 'day' in sentence 3 is unnecessary if the sentence is already clear and correctly structured without it. This option does not resolve a significant error; hence, it is not the best choice for correction.

C) Changing the comma to a period in sentence 4

This option effectively corrects the error by separating two independent clauses that are improperly joined by a comma. By turning the comma into a period, each clause can stand alone, enhancing clarity and grammatical accuracy.

D) Adding an apostrophe after the 't' in 'its' in sentence 5

This option is incorrect as 'its' is the correct form used to denote possession. Adding an apostrophe would change the meaning to a contraction ('it's'), which is not appropriate in this context. Therefore, this option does not correct an error.

Conclusion

Changing the comma to a period in sentence 4 is the only option that effectively addresses a grammatical error by properly punctuating independent clauses. The other options either do not correct errors or alter the intended meaning of the sentences, making them less suitable for correction. Thus, option C is the definitive choice for improving the excerpt.
