1. What structure links the nasopharynx to the middle ear?

• A. Larynx
• B. Pharyngeal muscles
• C. Eustachian tube
• D. Bronchus

Correct answer: C

Rationale: The Eustachian tube is the structure that connects the nasopharynx to the middle ear. It functions to equalize pressure between the middle ear and the atmosphere, protecting the eardrum from damage and aiding in the drainage of fluid from the middle ear. This connection is essential for maintaining proper ear function and health. The larynx (Choice A) is not the correct structure that links the nasopharynx to the middle ear. Pharyngeal muscles (Choice B) are involved in swallowing and do not directly link the nasopharynx to the middle ear. The bronchus (Choice D) is part of the respiratory system and is not connected to the middle ear.

2. A school has 500 students, and 60% of them are girls. How many girls are there in the school?

• A. 250 girls
• B. 300 girls
• C. 200 girls
• D. 350 girls

Correct answer: B

Rationale: Correct! To find out how many girls are in the school, you need to calculate 60% of 500. 60% of 500 is 0.6 * 500 = 300. Therefore, there are 300 girls in the school. Choice A (250 girls) is incorrect because 60% of 500 is not 250. Choice C (200 girls) is incorrect as it is less than 300. Choice D (350 girls) is incorrect as it is more than 300.

3. Which of the following words or phrases fits best in the following sentence? If you ever ___________ at County Medical, you would know how grueling a shift there can be.

• A. work
• B. are working
• C. had worked
• D. working

Correct answer: A

Rationale: The word 'work' (option A) is the most suitable choice for the sentence. The sentence is in the simple present tense and is discussing a general scenario or experience. The present simple tense is used to describe habits, routines, or general truths. Therefore, the word 'work' best fits in this context to indicate a general experience at County Medical without specifying a particular timeframe. Choices B, C, and D create incorrect tenses or imply specific past actions, which do not align with the intended meaning of the sentence.

4. A nurse works in the military hospital from 1300 to 2000. How many hours does this nurse work?

• A. 8 hours
• B. 11 hours
• C. 7 hours
• D. 12 hours

Correct answer: C

Rationale: The nurse works from 1300 to 2000, which is a 7-hour period. To calculate the hours worked, subtract the start time from the end time: 2000 - 1300 = 700, which is equal to 7 hours. Choice A, 8 hours, is incorrect as it does not reflect the actual duration. Choice B, 11 hours, is incorrect as it overestimates the hours worked. Choice D, 12 hours, is incorrect as it is also an overestimation of the hours worked.

5. Which statement from the passage on Voice is a fact rather than an opinion?

• A. One of the worst voice qualities is harshness.
• B. Harsh voice qualities come from tension in the throat.
• C. Your voice will sound unpleasant if it is shrill or grating.
• D. Because tension occurs in higher-pitched voices, women tend to have shriller voices than men.

Correct answer: B

Rationale: The correct answer is B. The fact that harsh voice qualities come from tension in the throat is a verifiable statement based on a scientific explanation provided in the passage. This statement is not subject to personal interpretation or judgment. Choice A is an opinion as it categorizes harshness as one of the worst voice qualities, which is subjective. Choice C is also an opinion as it describes how a voice will sound based on subjective terms like 'unpleasant.' Choice D is an opinion as it makes a generalized statement linking higher-pitched voices with shriller voices in women, which can vary widely among individuals.
