The word "good" is an adjective and should describe a noun. Here, it describes the verb "went" and is grammatically incorrect. Changing "good" to the adverb "well" corrects the sentence's error. The corrected sentence reads, "Despite the terrible dress rehearsal the night before, the opening performance of Romeo and Juliet went really well."

This sentence uses an adjective (“complete”) to describe another adjective (“wrong”). An adverb is the correct part of speech in this context. The corrected sentence reads: "Tom had a terrible sense of direction but a wonderful sense of humor; he consistently headed off in the completely wrong direction but laughed about it later."

In this sentence, the adjective “painful” is used to describe the verb “dragged on.” As adjectives only describe nouns and pronouns, "painful" contains the sentence's error, and the adverb "painfully" would be a grammatically correct choice. The corrected sentence reads, "May dragged on painfully; Dorothy was counting the hours until graduation, and they couldn’t pass fast enough."

"Then" is an adverb that means at that particular moment, and "than" is an adverb used to compare two things, as in the sentence, "My fall coat is less heavy than my winter coat." So, "then" is being used incorrectly in this sentence and should be replaced with "than" in order to correct the sentence's error.

In this sentence, "uneven" is meant to modify the verb "baked." Therefore, an adverb is needed. However, "uneven" is an adjective. The adverbial form is "unevenly," so the correct sentence would read, "Because the oven did not heat properly, Megan's cupcakes baked unevenly; some were burnt and overdone, while others were still raw and runny." Remember that adjectives only modify nouns, and adverbs modify verbs, adjectives, or other adverbs.

In this sentence, the adjective “slow” is used to modify the verb “crept.” Adjectives should only modify nouns and pronouns, so to correct the sentence's error, the adjective "slow" should be replaced with the adverb “slowly." The corrected sentence reads, "The sloth crept slowly across the roadway, risking life and limb in his determination to explore the world on the other side."

In this sentence, the adjective “quick” describes the verb “remove.” An adverb would be more appropriate. The corrected sentence reads: Chad’s political views took an abrupt swing to the left, and he had to find a way to remove bumper stickers quickly.

the words "careful and slow" are describing the verb "carried," and so should be adverbs instead of adjectives. The correction would be "carefully and slowly."

In this sentence, the adjective “similar” modifies the verb “dressing.” As adjectives can only modify nouns and pronouns, an adverb should be used instead. The corrected sentence reads, "I could never distinguish between the two Johnson twins, and their mother did not help matters by dressing them similarly."

In this sentence, the first "good" (in "Playing a brass or woodwind instrument good") is incorrect; "good" is an adjective, and this "good" is used to describe the way in which one plays a brass or woodwind instrument, so it needs to be changed to "well," which is an adverb, because adjectives cannot describe verbs, but adverbs can.
