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.

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 root words would be used in a word related to the body?
- A. corp
- B. auto
- C. man
- D. bio
Correct Answer: A
Rationale: The root word 'corp' is related to the body as it comes from the Latin word 'corpus,' meaning body. Words like 'corporal' and 'corporation' are derived from this root, linking them to the body in some manner. Choices B, C, and D are incorrect. 'Auto' relates to self or automatic, 'man' pertains to human or hand, and 'bio' is associated with life or living organisms, none of which directly signify the body.
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.
Which of the following phrases follows the rules of capitalization?
- A. President Carter and his advisors
- B. Robert Jones, the senior Senator from California
- C. my Aunt and Uncle who live out West
- D. the party on New Year's Eve
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.
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.
