One of these girls_______sick

One of these girls is sick.

To fill in the blank in the sentence "One of these girls _______sick," you'll need to determine the correct form of the verb to complete the sentence. In this case, the verb should agree with the subject "One of these girls."

The word "sick" in the sentence suggests that the verb should be in the present tense to indicate the current condition of one of the girls. There are a few options for filling in the blank:

1. "is" - This option indicates that one of the girls is currently sick. The verb "is" agrees with the singular subject "One."

2. "are" - This option indicates that multiple girls are currently sick. The verb "are" agrees with the plural noun "girls."

To determine which option is correct, you need to understand if "one" or "girls" is the subject of the sentence. If one of the girls is sick, then "One" is the subject, and you would use "is" to complete the sentence. However, if multiple girls are sick, then "girls" is the subject, and you would use "are" to complete the sentence.

Without further context, it's difficult to determine the correct option.
