After throwing their sleeping bags into the backseat of their car, they drove more than 400 miles to reach their destination

The word "drove" is the past tense form of the verb "drive," which is appropriate for describing the action that occurred after they threw their sleeping bags into the backseat of their car. The sentence requires a past tense verb to maintain grammatical consistency. Therefore, option B is the correct choice.

The contraction "they're" combines the pronoun "they" with the verb "are." It is a shortened form used to represent the combined words in a more concise and informal manner. The apostrophe in "they're" replaces the missing letter "a" from "are."

The other options are not the correct contractions for "they are."

Option A, "their," is a possessive pronoun indicating ownership. It is not a contraction for "they are."

Option B, "the're," is not a valid contraction in English. The correct form is "they're."

Option D, "No Contraction used," is not the correct answer because "they're" is the appropriate contraction for "they are."

Therefore, the correct contraction for "they are" is "C. They're."

He felt bad about the broken window.

The word "badly" is an adverb that describes how an action is performed. In sentence A, "He felt badly about being late," the adverb "badly" is used to describe the verb "felt," indicating that he felt in a poor or inadequate manner. However, it would be more appropriate to use the adjective "bad" to describe the feeling itself, as in sentence C, "He felt bad about the broken window."

Sentence B, "He did bad on the test," is incorrect because the adjective "bad" should be used instead of the adverb "badly" to describe how he performed on the test. Therefore, it should be "He did badly on the test."

Sentence D, "When the patient feels badly, give him an aspirin," is also incorrect because, in this case, the adverb "badly" is used to describe how the patient feels, which is grammatically incorrect. Instead, the adjective "bad" should be used to describe the patient's condition, as in "When the patient feels bad, give him an aspirin."

The correct conjunction to use in this sentence is "then," not "than."

The correct sentence would be: "The nurse decided to bathe the client, then trim his nails."

The conjunction "then" is used to indicate the chronological sequence of actions. It shows that the nurse first decided to bathe the client and then proceeded to trim his nails.

The option D contains the incorrect conjunction "than," which is used for making comparisons and is not suitable in this context.

Therefore, option D is the sentence that is not grammatically correct.
