Correct Answer: B

Rationale: The subject 'employer' in sentence B agrees with the singular verb 'decided.' In subject-verb agreement, singular subjects need singular verbs, while plural subjects need plural verbs. The use of 'decided' correctly pairs with the singular subject 'employer' in this sentence. Choice A is incorrect as the subject 'Akhal-Teke horse breed' is singular and should be paired with the singular verb 'has,' not 'have.' Choice C is incorrect because the verb 'play' does not agree with the plural subject 'mountains'; it should be 'play host' or 'are home to.' Choice D is incorrect as 'Each of the storm chasers' is a singular subject and should be paired with the singular verb 'decides,' not 'decide.'

Correct Answer: D

Rationale: In the context of the sentence, 'prized' is used to describe how much people value parrots as pets. Synonyms for 'prized' in this context would include esteemed, cherished, or valued, making option D the most suitable choice. Options A, B, and C do not accurately capture the meaning of 'prized' in this sentence.

Correct Answer: B

Rationale: The correct answer is B. In this phrase, the words 'Senator' and 'California' are capitalized correctly since they refer to a specific position and a proper noun, respectively. 'Senator' is capitalized as it is part of the title and 'California' is capitalized as a proper noun. Choice A is incorrect because 'President' should be capitalized when it precedes a specific name, like 'President Carter.' Choice C is incorrect because 'Aunt' and 'Uncle' are not proper nouns and should not be capitalized. Choice D is incorrect because only 'New Year's Eve' should be capitalized as it is a proper noun for the event.

Correct Answer: A

Rationale: The correct answer is A: "intra-". The prefix "intra-" is used to indicate that something is inside or within. For example, "intracellular" means within a cell, and "intrapersonal" means within oneself. Choice B, "trans-", typically indicates across, beyond, or through, not inside or within. Choice C, "anti-", is used to indicate against or opposed to. Choice D, "hyper-", usually denotes excessive or above normal levels, not inside or within.

Correct Answer: D

Rationale: The statement that 'Heat engines can be broken down into combustion and non-combustion engines' is correct. Heat engines can indeed be categorized into combustion engines, where fuel combustion occurs, and non-combustion engines, such as steam engines, where heat is applied without combustion. This categorization helps in understanding the different mechanisms and types of heat engines available. Choices A, B, and C are incorrect. Choice A is incorrect as heat engines are not the most common type of engine; internal combustion engines are more prevalent. Choice B is incorrect as pneumatic and hydraulic motors are not types of electric engines, but rather different systems that use gas (pneumatic) or liquid (hydraulic) to transmit power. Choice C is incorrect as it lists electric engines, which are not a primary classification of engines like heat engines, but rather a type of engine that uses electricity to operate.
