Pronouns should agree with their noun antecedents in number and case ("this" with the singular "category;" "those" with the plural and inanimate "things;" "that" with the nominative "things"). "It's," being a contraction of "it is," is not a pronoun!

The clause at the beginning of the sentence modifies "the court," so that must be the subject of the sentence. Otherwise, the clause would be considered a dangling modifier. Additionally, the pronoun "she" is incorrectly used. Since the pronoun is functioning as the object of the preposition "between," it must be an objective-case pronoun. In order to be correct, it must be changed to "her," as in "the agreement is between her and the family trust."

In the underlined portion of the sentence, "the grocery chain" is singular, but the chain's "clientele" is referred to with a plural pronoun, "their." The pronoun must be changed to the possesive singular pronoun, "its." As the only answer choice that makes this correction, "the grocery chain was seeking to offer its clientele more local and organic products to meet new consumer demands" is the correct answer choice.

Because "all workers" is plural, the pronoun that refers to it as its antecedent must also be plural. Thus, the correct version of the sentence is: "It is explicitly stated in the employee handbook that all workers must provide their own steel-toed shoes."

If the workers are made individual ("each worker") then the correct pronoun form would be "his or her," because the individual pronoun is required but the gender of the worker is not specified.

This sentence uses a correlative conjunction ("Neither . . . nor") to connect two antecedents; therefore, the pronoun must agree with the second antecedent, in this case "the employees," which is plural. Thus, the correct pronoun is "their." 

The use of the plural pronoun "they" is wrong in this sentence, as a pronoun must always be in agreement with its antecedent, which in this sentence is each of the singular nouns "a supervisor" and "an employee." The pronoun should be changed to an appropriate singular form. As the only option that makes this change, "had a workplace issue, he or she was supposed to take" is the correct answer choice.

In this sentence, the use of the demonstrative pronoun "those," which indicates a plural antecedent, is not in agreement with the singular subject of "strategy." The pronoun should be changed to a singular form to be in agreement with the subject. There is only one answer choice that makes this change, "a remarkable departure from the one laid," which is the correct answer.

The pronoun "it" should be plural because its antecedent is the plural subject "resources." Only two choices correcty change "it" to "they," but one of them, "as they depend on the reduction of foreign oil," confuses cause and effect. The resources are not dependent on the reduction of foreign oil. The correct answer is "as they may reduce our dependence on foreign oil."

The sentence as written contains one small error. "It," a singular pronoun, is used to refer to the plural "sporting events." In order to fix this issue, the pronoun needs to be made plural, which is done in "Most men who go to sporting events find them an enjoyable diversion."

In this sentence, the subject is "anyone," a singular pronoun. Therefore, all pronouns relating back to "anyone" should be singular. In the underlined portion of the sentence, "preparing a plan that they stick to," "they" is plural, not singular. Now that we have identified the problem, we have to figure out how to correct it.

Given that "anyone" is gender neutral, the best way to improve this sentence is avoid the use of a gendered pronoun (meaning "he" or "she") and simply avoid using a pronoun at all. The correct answer, "preparing a plan and sticking to it," accomplishes this objective and is therefore the best way to improve the sentence.
