Eliminate the choices containing ambiguous pronouns, as it is not clear to whom "their," "one," and "they" refers. Note that the correct answer adds the necessary auxiliary verb "do". The use of the noun in "how infant's..." resolves any issues with ambiguity.

The use of "they" in the underlined portion of the sentence is ambiguous and confusing, as it is unclear whether "they" refers to the "bettors" or the "team." The best way to clear up this confusion is to not use the pronoun at all, but rather to replace it with the actual noun it replaces. The only answer choice which properly clears up this confusion is "as the team had only a spotty track record of success."

The use of "I" at the end of this sentence is incorrect, as it is a subjective pronoun used as the object of the preposition "to." Pronouns used as objects of prepositions need to be in their objective, not their subjective forms. As it is used in the sentence, "him" is correct, since it is also an object of "to," but it is an objective pronoun. "I," on the other hand, needs to be changed to its objective form, "me." The correct answer choice is the only one that makes this change, "until the committee talks to both him and me."

The use of "it's" as it is used in this is incorrect. "It's" is the contraction of "it is," and not as the possessive form of "it"; the possessive form of "it" is "its." Only one choice uses the correct form, "ever ran properly was in it’s original demonstration," making it the correct answer.

The use of the pronoun "her" in the underlined phrase is confusing, as it is not clear whether this is a new person in the sentence or refers back to the subject. To be more clear, a reflexive pronoun must be used. The correct answer is "hard on herself."

The only issue in the sentence as it is written is the use of "myself," a reflexive pronoun, when there is no other first person pronoun to which it can refer back. The only answer choice which both appropriately uses "me," and keeps the same meaning is "back to me."

The only issue with the sentence is its use of the reflexive pronoun "myself," despite not previously using a first person pronoun. All reflexive pronouns need an antecedent, or previous pronoun in the same person, to be used correctly, or it should be changed to the simple pronoun. As this is the only problem with the sentence, "given to me" is the correct answer choice.

The only issue with the sentence is the use of the reflexive pronoun "myself" without a previous use of the first person pronoun. All reflexive pronouns need to refer back to an earlier use of the pronoun in the sentence. The solution to this issue is to change "myself" to the simple "me," making "directly to me" the correct answer choice.

The use of the reflexive pronoun "yourself" is incorrect in this sentence, as it has no previous "you" to refer back to. "Yourself" needs to simply be replaced by "you," making "reviewed by you" the correct answer choice.

The use of "myself" in the sentence is incorrect. "Myself" is a reflexive pronoun, meaning it needs an earlier first person pronoun to refer back to. The appropriate word in this situation is just "me," and that is the only issue with the sentence; therefore, "brought to me" is the correct answer.
