Correct Answer: B

Rationale: The correct word to make the sentence grammatically correct is 'too.' In this context, 'too' means excessively or to a higher degree, indicating that the person is extremely uncomfortable and needs another pillow. 'To' is a preposition and does not fit the context of the sentence. 'Much' is an adverb used to refer to a large quantity, not the degree of discomfort. 'Lesser' is a comparative adjective, which is not suitable for expressing the level of discomfort in this sentence. Therefore, 'too' is the most appropriate choice to convey the intended meaning.

Correct Answer: B

Rationale: The correct pronouns to use as objects of the verb 'told' are 'her' and 'me.' Therefore, the grammatically correct sentence is: 'Dr. Chu told her and me to take a break for lunch.' 'Her' is used as the object form of 'she,' and 'me' is the object form of 'I' in this context. Choice A is incorrect because 'me' should come before 'her' in the sentence. Choice C is a duplicate of the correct answer. Choice D is incorrect because 'she' should be 'her' and 'I' should be 'me' to function as objects in the sentence.

Correct Answer: B

Rationale: The word 'whom' should be used instead of 'who' in the sentence to make it grammatically correct. 'Who' is used as the subject of a sentence, while 'whom' is used as the object. Therefore, the correct form of the sentence should be: 'For whom was that email intended?' Choices A, C, and D are used correctly in the sentence and do not need any changes.

Correct Answer: B

Rationale: A comma is needed to separate the items being listed (notebook and small handmade coffee mug) in the sentence. This punctuation mark helps to clearly indicate the individual components being mentioned in a list. In this case, a comma is used in a series (also known as a list) to separate the items listed, ensuring clarity and proper punctuation structure. The other choices are incorrect because a period would create two separate sentences, a colon is used to introduce a list or an explanation (neither of which is the case here), and a hyphen is used to join words or parts of words.
