The "waterfall" makes the "general" have a feeling of astonishment. The sentence as written makes this quite confusing. To make it correct grammatically, the form of the word needs to be something the general does. "Still astonished at the massive waterfall" is the correct answer choice.

The use of the verb form "sticking," a past participle," makes the action of the sentence unclear, as such forms usually need an extra verb to clarify the action. The verb form should be change to an active tense. Thus, "the painter stuck closely" is the correct answer choice.

The sentence as constructed does not actually contain a verb. "Having" in this sentence is the present participle, which always needs a form of the verb "to be." In this sentence, the appropriate form is "are," the plural form, making "The girls are having a party" the correct answer.

The use of "marching" makes the sentence not have a verb, as the participle form always needs some form of the verb "to be" used immediately before it to make it a complete verb. (For example, it's not grammatically correct to say "The fish swimming across the lake." Anyone who heard this might ask, "The fish swimming across the lake did what?" since "swimming" is a participle—a verb acting like an adjective. Instead, the correct way to say this would be, "The fish was swimming across the lake," or, alternatively, use a different verb form altogether, such as "The fish swam across the lake." To correct the problem's sentence, either the participle "marching" needs to be preceded by some form of the verb "to be," or it should be changed to some other form than the present participle to avoid functioning as an adjective and instead clearly function as the sentence's verb. The only answer choice that uses either of these options is "The battalion marches towards the battlefield on their way to the conflict."

"Having angering" is a universally incorrect construction, and needs to be made appropriate grammatically. The -ing verb form following a comma that ends a complete thought is a participial modifier, which modifies the result of that clause. Here the result of "issues began cropping up" is that consumers became angry (at those issues). Using "angering" as the modifier, then, makes complete sense: the issues angered the consumers, so "angering consumers" properly uses a participial modifier to describe the effect of the action that takes place before the comma. "angering consumers" is correct.

The use of the patriciple form "having" is incorrect in the sentence, as the participle cannot stand on its own as the verb of the sentence. The word needs to be changed, and must match the later use of the past tense construction "that they could not." The correct answer, therefore, is "the man had issues."

Here, the correct form of the present perfect is “wouldn’t have had to sleep,” not “wouldn’t have have to sleep.”

The form of the sentence requires that we use the past perfect (e.g. "I had done something") instead of the present perfect (e.g. "I have done something") since the speaker is discussing the time "before [he or she] began volunteering at the shelter." The correct form of the past perfect is “I’d,” a contraction of “I had," instead of "I've," a contraction of "I have."

Here, we have a simple verb error. The correct form is always “supposed to,” never “suppose to.”

We have another simple verb error here. Despite how it sounds in spoken dialogue, the correct form is always “wouldn’t have” and never “wouldn’t of.”
