This sentence will try to trick you into using the subjunctive mood, but remember that the subjunctive is only used to describe hypothetical situations and dreams. Because the character actually did jump into the murky lake, the correct mood is simply the past indicative: “He said he wouldn’t have jumped into the murky lake if someone else hadn’t jumped before him.”

The correct answer choice ("The cheese was given to the child by the parent") uses the active voice instead of the passive voice and makes the most grammatical sense in the sentence. Sometimes the passive voice is necessary, but when it is not necessary, it should be avoided.

The phrase "to correcting" is grammatically incorrect in standard written English, and needs to be "to correct" in the underlined phrase. 

The example sentence expresses a hypothetical condition that is contrary to fact ("I," by definition, am not "you"), and therefore needs to be expressed using verbs in the subjunctive mood. "If" is a usually a good indication that a sentence will be in the subjunctive mood. In the subjunctive, "were" should be used instead of "was." "If I were you, I would leave that job immediately."

This sentence is an example of the present subjunctive, which is most commonly used in English to express hypothetical situations, wishes, and desires. The correct long form of the sentence is “if you were to choose that restaurant,” and “were you to choose that restaurant” is simply an inversion and shortening of the long form. (“Were you to have chosen that restaurant” is the past subjunctive, which doesn’t match the future conditional form of the second half of the sentence.)

The choices that include the pronoun "it" are clearly wrong because there is no noun preceding the word "it" that can be referenced. This question involves a dangling modifier. What is touching on those subjects? The novel. The novel should therefore come after the comma. Eliminate answers that do not have this structure. "Shall" is not usually used in the third person. It is usually used in the first person. It is used to make suggestions or to give offers of help. For example, "shall we go the beach" and "shall I help you with those bags". The sentence is correct as written.

The sentence is correct because we change "was" to "were" following a noun in situations in which the statement communicates something contrary to fact or highly unlikely.

The choices that include the pronoun "it" are clearly wrong because there is no noun preceding the word "it" that can be referenced. This question involves a dangling modifier. What is touching on those subjects? The book. The book should therefore come after the comma. Eliminate answers that do not have this structure. "Must" is clearly awkward. "Shall" is not usually used in the third person. It is usually used in the first person. It is used to make suggestions or to give offers of help, for example, "shall we go to the beach" and "shall I help you with those bags". The correct choice implements the simple structure "the book will tell".

The sentence as originally written attempts to be concise in its language, but does so at the expense of clarity and understanding. Simply adding in a small phrase to more adequately explain the full meaning of the phrase will greatly improve the sentence. The answer choice which best accomplishes this task is "with the original legislation giving proscribed limits to be used under certain circumstances."

The use of the present participle "having" makes the sentence not actually contain a verb, as a participle links to other verbs to create present action. The word needs to be changed to the present active verb form to make the sentence gramatically correct. "Historians have long noted the sharp discrepancy" is the only answer choice which appropriately makes the correct change.
