Question 1 of 5

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.

Question 2 of 5

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.'

Question 3 of 5

Parrots, among the most intelligent birds in the world, have been prized pets for many centuries; in fact, the first recorded instance of parrot training was written in the thirteenth century. Which of the following is a synonym for prized as used in the sentence?

A. unlikely B. misunderstood C. rewarded D. valued

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.

Question 4 of 5

Today, astrophysicists study the same stars that were observed by the astronomers of the ancient world, though today's techniques and technology are much more advanced. Which of the following is misspelled in the sentence?

A. astrophysicists B. astronomers C. techniques D. technology

Correct Answer: B

Rationale: The misspelled word in the sentence is 'astronemers,' which should be spelled as 'astronomers.' 'Astrophysicists,' 'techniques,' and 'technology' are all correctly spelled words in the sentence. Ensuring proper spelling is essential for effective communication and clarity. The term 'astronomers' refers to individuals who study celestial bodies, including stars, making it the correct answer in this context.

Question 5 of 5

Which of the following would most likely be found in an academic research paper on the world's food supply?

A. It is ridiculous that so many people in the world are hungry while others just throw away tons of uneaten food. B. I have always believed that it is our moral duty as a people to provide food and clean water to those who do not have access to it, which is why I have made research of the food supply my life's work. C. Advances in agricultural technology over the past five decades have led to a steady increase in the global food supply, and the populations of many countries around the world are benefiting. D. Poor people should appeal to their governments for help feeding their families.

Correct Answer: C

Rationale: Option C is the most likely to be found in an academic research paper on the world's food supply because it presents a factual statement about advances in agricultural technology leading to an increase in the global food supply. This type of information is commonly featured in academic research papers as it highlights trends, developments, and impacts on global food systems. Options A, B, and D are more opinion-based or advocacy-oriented statements, which are typically not the focus of academic research papers. Academic research papers aim to present objective information, data-driven analysis, and scholarly insights rather than personal opinions or advocacy perspectives.
