Correct Answer: B

Rationale: The word 'enthusiastic' is used incorrectly in the sentence. It should be 'enthusiastic' instead of 'enthusiastically' since it is describing Jeremiah's state of being, not an action he performed. Adverbs like 'enthusiastically' are used to modify verbs, not adjectives like 'enthusiastic'. The other choices ('seemed,' 'astonishing,' 'success') are all used appropriately in the sentence and do not need any correction.

Correct Answer: C

Rationale: The word 'otherwise' is used to indicate that although the patients are resting comfortably, under different circumstances, bed checks should still be done every half hour. This maintains the correct logic and flow of the sentence, making it grammatically correct. Choice A, 'despite,' would imply a contrasting situation that is not the intended meaning in this context. Choice B, 'however,' also implies a contrast rather than the intended conditional relationship. Choice D, 'afterward,' indicates a time sequence that does not fit the context of the sentence.

Correct Answer: D

Rationale: In the sentence, 'Could Kendra manage to carry both Kendra's books and yours?', the possessive pronoun 'hers' is the best substitution for the underlined words. The use of 'hers' correctly indicates possession by Kendra, making it the most appropriate word choice to replace 'Kendra's books'. Choice A, 'her', is incorrect as it refers to the possessive form of a singular female noun, not being possessive of 'Kendra'. Choice B, 'his', is incorrect as it is the possessive pronoun for a singular male noun, not suitable for replacing 'Kendra's books'. Choice C, 'she's', is incorrect as it is a contraction for 'she is', which does not fit the possessive context needed in the sentence.

Correct Answer: C

Rationale: In the context of the sentence, the word 'then' is used incorrectly. The correct word that should be used is 'than,' which is used to make comparisons. The sentence should read, 'Nothing can be more delightful than a late-night swim in the reservoir.' The other choices 'Nothing,' 'delightful,' and 'reservoir' are spelled correctly and are contextually appropriate in the sentence.

Correct Answer: B

Rationale: The correct punctuation needed in the given sentence is a comma after 'class.' This comma is necessary to separate the two independent clauses 'Do not be afraid to ask questions in his class' and 'he is very approachable and explains things well.' Commas are used to separate independent clauses when they are joined by a coordinating conjunction like 'and.' Choice A, 'Hyphen,' is incorrect as a hyphen is not needed to connect any words in the sentence. Choice C, 'Apostrophe,' is incorrect as there is no possession or contraction being indicated in the sentence that requires an apostrophe. Choice D, 'Semicolon,' is incorrect as a semicolon is not used to join two independent clauses in this context; a comma followed by a coordinating conjunction is more appropriate.
