1. How will mildly elevated levels of thyroxine affect the heart rate?

• A. Stop the heart rate
• B. No effect
• C. Decrease the heart rate
• D. Increase the heart rate

Correct answer: D

Rationale: Mildly elevated levels of thyroxine will increase the heart rate. Thyroxine, a hormone produced by the thyroid gland, regulates metabolism. Elevated thyroxine levels can lead to increased metabolism, resulting in an elevated heart rate. Choice A is incorrect as mildly elevated thyroxine levels do not stop the heart rate. Choice B is incorrect because elevated thyroxine levels do have an effect on heart rate. Choice C is incorrect as elevated thyroxine levels typically lead to an increase rather than a decrease in heart rate.

2. How much will Raoul expect to pay for his computer use at the library?

• A. $9
• B. $6
• C. $12
• D. $15

Correct answer: A

Rationale: Raoul estimates that he will need to use the library computer for approximately an hour and a half. Since each 15-minute period beyond the initial 30 minutes incurs a $3 charge, for a total of three additional 15-minute periods, Raoul will need to pay $9 ($3 x 3 = $9). Therefore, Raoul can expect to pay $9 for his computer use at the library. Choices B, C, and D are incorrect as they do not align with the information provided in the extract.

3. Which of the following sentences is grammatically correct?

• A. Krista was not sure who to hold responsible for the broken window.
• B. Krista was not sure whom was responsible for the broken window.
• C. Krista was not sure whom to hold responsible for the broken window.
• D. Krista was not sure on who she should place responsibility for the broken window.

Correct answer: C

Rationale: The correct structure is 'whom to hold responsible' as 'whom' is the object of the verb 'to hold.' In choice A, 'who' should be 'whom' to indicate the object of the verb. Choice B is incorrect as 'whom' is incorrectly placed before 'was responsible.' Choice D is also incorrect due to the awkward phrasing and the use of 'on' which is unnecessary.

4. Which of the following is an example of a chemical change?

• A. Dissolving sugar in water
• B. Boiling water
• C. Rusting iron
• D. Crushing ice

Correct answer: C

Rationale: Rusting iron is an example of a chemical change because it involves a chemical reaction where iron reacts with oxygen in the presence of water to form iron oxide (rust). This reaction results in a change in the chemical composition of the iron, unlike dissolving sugar in water, boiling water, or crushing ice, which are physical changes. Dissolving sugar in water is a physical change as sugar molecules remain unchanged but disperse in water. Boiling water is also a physical change as water changes its state from liquid to gas due to heat. Crushing ice is a physical change as the solid ice changes its physical form without altering its chemical composition.

5. What is the main point of the passage?

• A. The narrator is gaining favor with the emperor and his court and experiencing cultural entertainment.
• B. The emperor is hosting a dance competition to determine high-ranking officials.
• C. The candidates for high offices are trained in rope-dancing to display their skills.
• D. The emperor's court engages in various entertainments to showcase their talents.

Correct answer: A

Rationale: The main point of the passage is that the narrator, through his gentleness and good behavior, is gaining favor with the emperor and his court. He describes how he interacts with the natives and experiences the country's shows, such as the rope-dancers. The passage focuses on the narrator's progress in understanding the language and his experiences with the cultural entertainment of the emperor's court. Choices B, C, and D are incorrect as they focus on specific details mentioned in the passage rather than the overall main point.
