What punctuation is needed in the following sentence to make it correct? Harvey, please make sure that the patient is resting comfortably.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is needed at the end of the sentence to indicate the completion of the thought and to make it a grammatically correct statement. The other options (comma, question mark, exclamation mark) do not fit the context of the sentence. In this case, a period is used to end a declarative sentence, stating a fact without needing any additional punctuation for the context provided.

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.

Correct Answer: A

Rationale: The correct punctuation needed in the sentence is a period. A period is used to indicate the end of a sentence. In this case, the sentence 'After you complete your rounds, please check in at the station.' is a complete thought and requires a period at the end to show that it is a complete sentence. The other choices are incorrect because a comma would not be suitable at the end of a sentence, a colon is used to introduce a list or an explanation, and a semicolon is used to connect two closely related independent clauses.

Correct Answer: C

Rationale: The correct option to substitute for 'Roseanne's' is 'her' to maintain correct pronoun-antecedent agreement. In this case, using 'her' makes the sentence grammatically correct and clear by referring back to Roseanne in a proper manner. Choice A, 'she,' is a subject pronoun and does not match the possessive form needed in the sentence. Choice B, 'their,' is plural and does not agree with the singular possessive 'Roseanne's.' Choice D, 'hers,' is a possessive pronoun but cannot directly replace 'Roseanne's' in this context; 'her' is the appropriate choice to indicate possession.

Correct Answer: D

Rationale: The word 'their' is the best substitute for the underlined words in the sentence because it refers to Stu's roommates in a possessive form, indicating that the housekeeping belongs to them. 'His' (Choice A) refers to Stu, not the roommates. 'Hers' (Choice B) is incorrect as it refers to a female possessive form. 'Them' (Choice C) is a pronoun for a group of people but does not show possession, making it unsuitable in this context.

Correct Answer: C

Rationale: The word 'study' is used incorrectly in the sentence. The correct verb form should be 'studies' to match the subject 'Sidney,' which is singular. The sentence should read, 'Jack practices piano while Sidney studies for the exam.' The other choices ('practices,' 'while,' and 'exam') are used appropriately in the sentence.

Correct Answer: C

Rationale: The correct punctuation needed in the sentence is a question mark. The sentence is a question, asking whether the lab results have been read in order to schedule an appointment. Therefore, a question mark is needed at the end of the sentence to indicate that it is an inquiry. The period is used for statements, not questions. A comma would not be appropriate here as the sentence is not a list or a compound sentence. An exclamation mark would imply excitement or surprise, which is not the tone of the sentence.

Correct Answer: A

Rationale: In the sentence provided, the word 'lay' is used incorrectly. The correct past tense of 'lay' in this context should be 'lay.' Therefore, the sentence should read, 'Dr. Leo laid the paperwork out upon the table for us to view.' 'Laid' is the past participle of 'lay' when it requires an object. In this sentence, 'lay' is the correct choice as it is used without an object. The other choices ('upon,' 'us,' 'view') are used appropriately in the sentence and do not contain any errors.

Correct Answer: B

Rationale: The word 'quickly' is used incorrectly in the sentence. The correct word that should be used here is 'speedily.' 'Quickly' is an adverb that describes the speed at which an action is performed. However, in this context, the sentence needs an adverb that conveys doing something in a hurried or rushed manner, which is 'speedily.' Therefore, the sentence should read as: 'If you calculate too speedily, you may possibly fail to get the right answer.' The other choices ('calculate,' 'possibly,' 'right') are used appropriately in the sentence and do not need to be changed.
