Which of the following words or phrases fits best in the following sentence? The radiology department sends Troy to pick up lunch ______ it isn't too busy at the office.

Correct Answer: A

Rationale: The phrase 'as long as' is used to indicate a condition that needs to be met for the main clause to happen. In this sentence, the radiology department sends Troy to pick up lunch only if it isn't too busy at the office, so 'as long as' is the most suitable phrase to convey this conditional relationship. Choice B, 'as if,' implies a hypothetical comparison rather than a condition. Choice C, 'after,' suggests a sequence of events rather than a condition. Choice D, 'unless,' introduces a negative condition which does not fit the context of the sentence.

Correct Answer: A

Rationale: The correct preposition to use in this sentence is 'with.' The sentence should read: 'Do not be afraid to consult with your peers.' In this context, 'with' is the appropriate preposition to indicate collaborating or seeking advice from your peers. The other prepositions ('from,' 'by,' 'in') do not convey the intended meaning of seeking advice or collaborating with your peers in this context.

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: D

Rationale: The phrase 'standing with the refrigerator door open' is misplaced in the sentence as it disrupts the flow. It seems to modify 'shelf,' but it actually relates to the subject's action. Placing it after 'orange juice' would enhance clarity and conciseness. Choice A, 'I did not see,' is the introductory part of the sentence and is correctly placed. Choices B and C, 'of orange juice' and 'on the shelf,' provide necessary information and are correctly positioned in relation to the main subject and verb.

Correct Answer: C

Rationale: In this sentence, 'Three days from now' indicates a future timeframe, so the correct verb tense to use is the future tense. The phrase 'will perform in a show' is the best choice to make the sentence grammatically correct because it aligns with the future action of the horses. Choice A ('performing in a show') uses the present participle and is incorrect in this context. Choice B ('performed in a show') uses the past tense, which is not suitable for a future event. Choice D ('have performed in a show') uses the present perfect tense, which is also not appropriate for a future action. Therefore, the correct answer is C.

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 phrase 'as long as' is used to indicate a condition that needs to be met for the main clause to happen. In this sentence, the radiology department sends Troy to pick up lunch only if it isn't too busy at the office, so 'as long as' is the most suitable phrase to convey this conditional relationship. Choice B, 'as if,' implies a hypothetical comparison rather than a condition. Choice C, 'after,' suggests a sequence of events rather than a condition. Choice D, 'unless,' introduces a negative condition which does not fit the context of the sentence.

Correct Answer: D

Rationale: The verb 'meet' is the correct option in this context as it completes the sentence structure 'waiting to meet with the doctor' in a grammatically correct way. The sentence requires an infinitive verb form to convey the intended meaning of Miguel and I waiting to have a meeting or appointment with the doctor. Choices A, B, and C are incorrect because 'be met' changes the meaning, 'meeting' is a gerund form which doesn't fit the sentence structure, and 'met' is a past tense form that doesn't match the present tense context of the sentence.

Correct Answer: C

Rationale: The correct spelling is 'embarrassing.' It is spelled with two consecutive r's and two consecutive s's. Option C is the only choice with the correct spelling. Options A, B, and D all have incorrect spellings. 'Embarrasing' (Option B) is missing an 'r,' and 'Emberassing' (Option D) has an extra 'e' and a missing 'r' and 's.' Therefore, the correct answer is Option C.
