Which of the following statements about heat engines is true?
- A. Heat engines are the most common type of engine.
- B. Pneumatic and hydraulic motors are both types of electric engines.
- C. The three types of engines are heat engines, electric engines, and pneumatic motors.
- D. Heat engines can be broken down into combustion and non-combustion engines.
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.
Which of the following prefixes would be used to indicate that something is inside or within?
- A. intra-
- B. trans-

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.
Which of the following nouns is written in the correct plural form?
- A. vertebrae
- B. geese
- C. octopuses
- D. potatoes
Correct Answer: D
Rationale: The correct plural form of 'potato' is 'potatoes.' In English, most plural nouns form by adding '-es' or simply '-s' to the singular form. Therefore, 'potatoes' is the correctly formed plural noun in this list. The other choices, 'vertebrae,' 'geese,' and 'octopuses,' are the correct plural forms of 'vertebra,' 'goose,' and 'octopus,' respectively. They demonstrate the common rule of adding '-es' or '-s' to form plural nouns.
Which of the following sentences follows the rules of capitalization?
- A. As juveniles, African white-backed vultures are darkly colored, developing their white feathers only as they grow into adulthood.
- B. Ukrainians celebrate a holiday called Malanka during which men dress in costumes and masks and play tricks on their neighbors.
- C. Because of its distance from the sun, the planet Neptune has seasons that last the equivalent of forty-one Earth years.
- D. Edward Jenner, considered the Father of Immunology, invented the world's first vaccine.
Correct Answer: B
Rationale: In sentence B, "Ukrainians" is capitalized because it is referring to a specific group of people, and "Malanka" is also capitalized as it is a holiday name. This follows the rules of capitalization for proper nouns. Choices A, C, and D contain correct capitalization, but they also include additional capitalizations that are unnecessary. For instance, in choice A, "African white-backed vultures" should not be capitalized unless it is part of a proper noun or a title. In choice C, while "Neptune" and "Earth" should be capitalized as they are names of celestial bodies, the word "sun" is not capitalized unless it is used as part of the proper noun "Sun." Choice D correctly capitalizes proper nouns like "Edward Jenner" and "Immunology," but the general terms like "Father" and "vaccine" do not need capitalization unless they are part of a title or a specific name.
Which of the following sentences has the correct subject-verb agreement?
- A. The Akhal-Teke horse breed, originally from Turkmenistan, has long enjoyed a reputation for bravery and fortitude.
- B. The employer decided that he could not, due to the high cost of health care, afford to offer other benefits to his employees.
- C. Though Puerto Rico is known popularly for its beaches, its landscape also includes mountains, which are home to many of the island's rural villages.
- D. Each of the storm chasers decides whether or not to go out when rain makes visibility low.
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.'
