The use of "for me" is a confusing and odd use of the pronoun. Normally, we might consider changing "for me" to "for myself," since "I" has already been used in the sentence and "myself" would have a clear antecedent. However, the phrase "for myself" isn't necessary in this sentence; the sentence still makes complete sense without the inclusion of the phrase. Omitting the underlined portion simplifies the sentence and is grammatically correct, and it is the only answer choice that both corrects the error contained in "for me" and doesn't introduce other grammatical errors.

The use of the reflexive pronoun "herself" in this sentence is incorrect and confusing, as no third-person female pronoun or name has been mentioned, so "herself" has no antecedent. The sentence only needs to use the simple female third-person objective pronoun "her." Therefore, the correct answer choice is "to her immediately, with no delays."

We need to chose a relative pronoun to replace "which" that can describe a person, because the pronoun is referring to Tony's teacher. Of the available answer choices, only "who" and "whom" can refer to people. "Whom" is an objective pronoun while "who" is a subjective pronoun. A trick for deciding which form to use in a sentence is to replace the pronoun with the word "him." If "him" makes grammatical sense, you need to use the objective form, "whom." In this sentence, it does not make sense to say "him hesitated before answering," so we need to use the subjective form, "who."

The use of the word "their" in the sentence is highly problematic, as it is both plural when the subject is singular and creates an odd referent. These issues can both be cleared by replacing it with the article "a," as in the correct answer choice "more than once in a lifetime."

The use of the reflexive pronoun is incorrect in the sentence, as "himself" needs a previous use of the third person pronoun to refer back to in its usage. This pronoun needs to be changed to the simple pronoun "him," and otherwise there are no further issues with the sentence. The correct answer choice is "for him."

The use of the reflexive pronoun "himself" is incorrect in the sentence as a reflexive pronoun needs to refer back to an earlier use of the regular pronoun of the same person. The pronoun needs to be changed to the simple "him," making "given to him" the correct answer choice.

When the "–ing" form of a verb is used as a noun (called a "gerund"), the pronoun immediately preceding it should be in the possessive form.

The sentence as written is incorrect because it does not specify what or whose "identities are protected" by "anonymous gifts." The correct answer needs to at least refer back to the "wealthy patrons" in order to explain their behavior. "So their identities are protected" is the best choice among the answers.

The sentence is correct as it is written. The use of "you" in this sentence is proper instead of "yourself," because "yourself" is a reflexive pronoun, meaning it needs to refer back to an earlier use of "you." 

The verb in the underlined portion is used with the "many issues," a plural. Therefore, the verb needs to be plural. Also, the word beginning the sentence needs to appropriately reference the "many issues." "There are" is the only answer choice that fits both criteria.
