1. 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.

2. During gas exchange in the alveoli, what happens to oxygen?

• A. Oxygen is released from the alveoli into the bloodstream.
• B. Oxygen is absorbed from the alveoli into the bloodstream.
• C. Oxygen is converted into carbon dioxide.
• D. Oxygen is stored in the alveoli for later use.

Correct answer: B

Rationale: During gas exchange in the alveoli, oxygen is absorbed from the alveoli into the bloodstream. This process occurs due to the difference in partial pressures of oxygen between the alveoli and the bloodstream, causing oxygen to move from an area of higher concentration (alveoli) to an area of lower concentration (bloodstream). Oxygen is then transported by red blood cells to tissues throughout the body for cellular respiration. Choice A is incorrect as oxygen moves from the alveoli into the bloodstream, not the other way around. Choice C is incorrect as oxygen is not converted into carbon dioxide during gas exchange. Choice D is incorrect as oxygen is not stored in the alveoli but rather continuously exchanged with carbon dioxide during respiration.

3. Select the correct words to complete the following sentence: I have ____________ due tomorrow.

• A. many homework
• B. many homeworks
• C. a lot of homework
• D. a lot of homeworks

Correct answer: C

Rationale: The correct answer is 'C: a lot of homework'. In this case, 'homework' is an uncountable noun, so it does not take a plural form like 'homeworks'. The phrase 'a lot of' is used to quantify uncountable nouns, making it the appropriate choice in this context. Choices A, B, and D are incorrect because 'homework' should not be pluralized, and the phrase 'many' is not suitable for uncountable nouns.

4. Approximately what percentage more staff members at Hospital Y are female than at Hospital X?

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: B

Rationale: To find the percentage more staff members at Hospital Y are female than at Hospital X, we first calculate the percentage of female staff members at each hospital. For Hospital Y: (90 / 183) x 100 ≈ 49.2%. For Hospital X: (97 / 250) x 100 ≈ 38.8%. The difference between these percentages is approximately 10%, making choice B the correct answer. Choice A, 5%, is too low as the difference is greater. Choice C, 15%, and choice D, 20%, are both too high as the actual difference is closer to 10%.

5. With which of the following statements would the author most likely agree?

• A. There is no real mystery about the Bermuda Triangle because most events have reasonable explanations.
• B. Researchers are wrong to expand the focus of the Triangle to the Azores, as this increases the likelihood of accidents.
• C. The official statement of 'causes or reasons unknown' in the loss of the Navy planes was a deliberate concealment from the Navy.
• D. Reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region.

Correct answer: D

Rationale: The author would most likely agree with the statement that reducing the legends about the mysteries of the Bermuda Triangle will help to reduce the number of reported accidents or shipping losses in the region. This aligns with the perspective that many events in the Bermuda Triangle can be explained logically and that dispelling myths and legends can lead to a more accurate understanding of the phenomena occurring in the area. Choice A is incorrect because the author acknowledges that the Bermuda Triangle has sparked interest due to unexplained events. Choice B is incorrect as expanding the focus of the Triangle to the Azores is not associated with an increase in accidents, according to the author. Choice C is incorrect as the author does not suggest a deliberate concealment but rather points towards logical explanations for the events in the Bermuda Triangle.
