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: B

Rationale: The word 'prescription' in the sentence is misspelled as 'proscription.' A prescription is a written order for medication or treatment provided by a healthcare professional, while a proscription means a forbidding or prohibition. The other choices (A, C, D) are all correctly spelled in the context of the sentence.

Correct Answer: A

Rationale: The correct sentence is 'Because she was uncertain of her abilities, Renee asked for help.' This sentence uses a comma after the introductory phrase 'Because she was uncertain of her abilities' to set it off from the main clause 'Renee asked for help.' The comma helps to separate the two parts of the sentence clearly and indicates the pause that should be there when reading it aloud. Options B, C, and D are incorrect because they either use a semicolon incorrectly or have commas placed incorrectly within 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: A

Rationale: The word 'because' indicates the reason or cause for something. In this context, it logically connects the meteorologist's forecast of rain with Sheila bringing her umbrella to work. The conjunction 'because' explains the relationship between the rain forecast and Sheila's action of bringing an umbrella, making it the most suitable word for the sentence. Choices B, C, and D do not fit the context as they do not provide a logical reason for Sheila's action.
