1. The author would be most likely to agree with which of the following statements?

• A. Smokers should only quit cold turkey.
• B. Other substances are more addictive than tobacco.
• C. Smokers should quit for any reason that makes them stop.
• D. People who want to smoke should advocate for reduced taxes.

Correct answer: C

Rationale: The author would likely agree that any reason to quit smoking is valid, based on their anti-smoking stance. The provided extract extensively discusses the harmful effects of smoking, the addictive nature of nicotine, and the negative consequences associated with tobacco products. The author emphasizes the health risks, financial burden, and social implications of smoking, promoting the idea that smokers should quit for any reason that helps them stop. Choice A, suggesting that smokers should only quit cold turkey, is too restrictive and doesn't consider individual differences in quitting methods. Choice B, stating that other substances are more addictive than tobacco, is not directly supported by the extract, which highlights the extreme addictiveness of nicotine. Choice D, proposing that people who want to smoke should advocate for reduced taxes, goes against the anti-smoking stance presented in the extract, which highlights the negative impact of smoking and high tobacco prices.

2. How do you convert Fahrenheit to Celsius and Celsius to Fahrenheit?

• A. Fahrenheit to Celsius: Subtract 32, then divide by 1.8; Celsius to Fahrenheit: Multiply by 1.8, then add 32
• B. Fahrenheit to Celsius: Subtract 32, then divide by 2; Celsius to Fahrenheit: Multiply by 1.8, then add 20
• C. Fahrenheit to Celsius: Multiply by 2, then add 32; Celsius to Fahrenheit: Subtract 32, then divide by 1.8
• D. Fahrenheit to Celsius: Subtract 30, then divide by 1.8; Celsius to Fahrenheit: Multiply by 2, then add 32

Correct answer: A

Rationale: To convert Fahrenheit to Celsius, you start by subtracting 32 from the Fahrenheit temperature and then divide the result by 1.8. This formula accounts for the freezing point of water at 32°F and the conversion factor to Celsius. To convert Celsius to Fahrenheit, you multiply the Celsius temperature by 1.8 and then add 32. This process takes into consideration the conversion factor from Celsius to Fahrenheit and the freezing point of water. Choice B is incorrect as dividing by 2 instead of 1.8 would yield an inaccurate conversion. Choice C is incorrect as it involves incorrect operations for both conversions. Choice D is incorrect as subtracting 30 instead of 32 for Fahrenheit to Celsius and multiplying by 2 instead of 1.8 for Celsius to Fahrenheit would provide incorrect results.

3. Which number is larger, 0.5 or 1/3?

• A. 0.5
• B. 1/3
• C. They are equal
• D. Cannot be determined

Correct answer: A

Rationale: To compare 0.5 and 1/3, we can convert 0.5 to a fraction, which is 1/2. When comparing 1/2 and 1/3, we find that 1/2 is greater than 1/3. Therefore, 0.5 is larger than 1/3. Choice B is incorrect as 1/3 is smaller. Choice C is incorrect as the numbers are not equal. Choice D is incorrect as a clear comparison can be made.

4. What role do the spiracles play in the respiration of the insects described in the passage?

• A. They allow insects to breathe atmospheric air even when submerged.
• B. They protect the insect's internal organs from water pressure.
• C. They filter oxygen from the water for underwater breathing.
• D. They are used to expel carbon dioxide from the body.

Correct answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

5. Which bone is the longest in the human body?

• A. Femur (Thigh bone)
• B. Humerus (Upper arm bone)
• C. Tibia (Shin bone)
• D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The correct answer is the femur (thigh bone) as it is the longest bone in the human body, extending from the hip to the knee. It plays a vital role in supporting the body's weight and enabling movement. The humerus is located in the upper arm and is not as long as the femur. The tibia is the shin bone and is shorter than the femur. The scapula is the shoulder blade and is not the longest bone in the body, making it an incorrect choice.
