While this sentence describes the way in which "Paula" speaks, her "elocution" is actually acting as a noun in this sentence, and thus an adjective is required. The correct version of this sentence reads, "Paula's elocution is very excellent: she has really become a phenomenal speaker."

In this sentence the way in which "Johnny" undertook the action of "eating his cake." Since verbs describe actions, we need an adverbial form of "grotesque" not an adjectival one. The correct sentence reads, "Johnny was eating his cake so grotesquely that I was taken aback."

Adjectives describe nouns, and adverbs describe verbs, adjectives, or other adverbs. In the example sentence "good" is meant to describe the verb "feel," so the adverbial, rather than the adjectival, form is required. The best way to correct the underlined portion of the sentence above is, "Whenever I eat at Pizza Hut, I don't feel very well afterwards."

Note also that a comma correctly connects the dependent introductory clause "whenever I eat at Pizza Shack" to the main clause.

Whenever you are comparing only two things, use the comparative form (usually words ending in "-er"—better, smarter, faster, and so forth). If there are three or more items, use the superlative form (usually ending in "-est"—best, smartest, fastest . . .) to designate the best one.

We use comparative adjectives when comparing two people or things (bigger, worse); we use superlative adjectives when comparing one person or thing with three or more people or things (the biggest, the worse).

We use comparative adjectives when comparing two people or things (bigger, worse, etc.); we use superlative adjectives when comparing one person or thing with three or more people or things (the biggest, the worst, etc.). Thus, here we use the superlative adjective “the shortest.” In the first clause, we use “me” instead of “I” because “me” is an object pronoun, and “me” is the indirect object of the verb “look.”.

The use of the form "strongest" is a superlative that indicates the peak of an adjective; therefore, there can be only one "strongest boy," and the phrase needs a definite article, "the," instead of the indefinite article, "a."

"More well" is not a phrase—the comparative form of "well" is not "more well," but "better." Since we are only comparing two groups (the speaker versus the speaker's friends), "better" is the most appropriate here.

In the sentence as it is written, "fast," an adjective, is being used to modify "walks." This is incorrect; only adverbs can modify verbs. So, we need to pick out an answer choice which uses the adverbial form of "fast," which is "quickly." This lets us eliminate the answer choice "most fast." "Faster" cannot be correct because more than two subjects are being compared in the sentence, and "faster" is a comparative adjective that is used to compare two subjects. "More quick," "more fast," and "more quickly" can each be eliminated for this same reason, in addition to the fact that "more quick" isn't grammatically correct at all—one would say "quicker," not "more quick." This leaves us with the correct answer, "most quickly."

We must compare the chefs to my mother, not to the home-cooked meals.
