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.

On Parents' Day, a public holiday in the Democratic Republic of Congo, families celebrate parents' both living and deceased. Which of the following punctuation marks is used incorrectly?
- A. the apostrophe in Parents' Day
- B. the comma following Day
- C. the comma following Congo
- D. the apostrophe in parents'
Correct Answer: B
Rationale: The comma following 'Day' is used incorrectly. Commas are typically not used after single-word identifiers like 'Day' in a sentence unless they are part of a list. In this case, the holiday is referred to as 'Parents' Day,' where the apostrophe is used correctly to indicate possession. The comma following 'Day' is unnecessary and should be removed for proper punctuation. Choices A and D both use apostrophes correctly to indicate possession, so they are not incorrect. The comma following 'Congo' in choice C is necessary to set off the introductory phrase 'a public holiday in the Democratic Republic of Congo.' Therefore, the correct answer is B.
What is the complete subject in the sentence: Sandra's principal reason for choosing the job was that it would be full-time and would offer benefits?
- A. Sandra's principal reason for choosing the job
- B. Sandra's principal reason
- C. Sandra's principal
- D. Sandra
Correct Answer: A
Rationale: The complete subject in a sentence includes all the words that describe the main focus of the sentence. In this case, the complete subject is "Sandra's principal reason for choosing the job" as it encompasses all the relevant details about Sandra and her reason for selecting the job. Choice A is the correct answer because it provides the most comprehensive and specific information, making it the complete subject. Choices B, C, and D are incorrect as they do not include all the necessary elements to form the complete subject and do not convey the full context of the sentence.
Which of the following is a complex sentence?
- A. When skywriting, a pilot flies a small aircraft in specific, particular formations, creating large letters visible from the ground.
- B. The public defense attorney was able to maintain her optimism despite her dearth of courtroom wins, her lack of free time, and her growing list of clients.
- C. Because the distance between stars in the galaxy is far greater than the distance between planets, interstellar travel is expected to be an even bigger challenge than interplanetary exploration.
- D. Invented in France in the early nineteenth century, the stethoscope underwent a number of reiterations before the emergence of the modern form of the instrument in the 1850s.
Correct Answer: C
Rationale: A complex sentence has one independent clause and at least one dependent clause connected by a subordinating conjunction or a relative pronoun. In choice C, the sentence 'Because the distance between stars in the galaxy is far greater than the distance between planets' is a dependent clause introduced by the subordinating conjunction 'Because,' while the rest of the sentence 'interstellar travel is expected to be an even bigger challenge than interplanetary exploration' forms the independent clause. This combination of an independent clause and a dependent clause makes choice C a complex sentence. Choices A, B, and D do not contain both an independent and dependent clause connected in the way that choice C does, thus they do not qualify as complex sentences.
Which of the following sentences has correct pronoun-antecedent agreement?
- A. The storm, which included three days of rain, was very strong, and it left half the city flooded.
- B. Each of the cars needs to be examined for damage by a mechanic; they may need repairs.
- C. The number of people who had to evacuate hasn't been confirmed, but it is small.
- D. Many people were able to take advantage of shelters, where they were kept safe from the storm.
Correct Answer: C
Rationale: Sentence C correctly maintains the pronoun-antecedent agreement. In this sentence, the antecedent is 'number of people,' and the pronoun 'it' is used to refer back to this antecedent. The singular pronoun 'it' matches the singular antecedent 'number,' making the sentence grammatically correct.
Choice A is incorrect because it uses the plural pronoun 'they' to refer back to the singular antecedent 'storm.'
Choice B is incorrect as it uses the plural pronoun 'they' to refer back to the singular antecedent 'each of the cars.'
Choice D is incorrect because it uses the singular pronoun 'he or she' to refer back to the plural antecedent 'many people.' This creates a lack of agreement between the pronoun and its antecedent.
Which of the following prefixes would be used to indicate that something is inside or within?
- A. intra-
- B. trans-
- C. anti-
- D. hyper-
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.
