1. Select the meaning of the underlined word in the following sentence. He made a posthumous donation to the clinic.

• A. Generous
• B. Immense
• C. Postmortem
• D. Time-honored

Correct answer: C

Rationale: The word 'posthumous' in this sentence means occurring or coming into effect after the person's death. It is related to the word 'postmortem,' which also refers to events or actions happening after death. Given the context of the sentence, the most suitable meaning is 'postmortem.' Choice A, 'generous,' does not accurately reflect the meaning of 'posthumous' in the sentence. Choice B, 'immense,' is unrelated to the concept of something happening after a person's death. Choice D, 'time-honored,' is also not synonymous with 'posthumous' and does not fit the context of the sentence.

2. How many milliliters are in 4 liters?

• A. 40 milliliters
• B. 40 milliliters
• C. 4000 milliliters
• D. 4 milliliters

Correct answer: C

Rationale: To convert liters to milliliters, you must remember that 1 liter is equal to 1,000 milliliters. Therefore, to find out how many milliliters are in 4 liters, you multiply 4 by 1,000. This gives you a total of 4,000 milliliters in 4 liters. Choices A, B, and D are incorrect because they do not correctly convert liters to milliliters. A and B incorrectly represent 40 milliliters, which would be the result if you mistakenly multiplied by 10 instead of 1,000. Choice D is even further from the correct answer, as it suggests only 4 milliliters, which is significantly less than the actual conversion of 4 liters to milliliters.

3. What is the function of the liver in digestion?

• A. To produce bile
• B. To store glucose
• C. To secrete digestive enzymes
• D. To detoxify harmful substances

Correct answer: A

Rationale: The liver's main role in digestion is to produce bile, a substance that aids in the breakdown and absorption of fats in the small intestine. Bile emulsifies fats, helping enzymes break them down into smaller molecules for easier absorption in the digestive tract. Therefore, the correct answer is A: 'To produce bile.' Storing glucose, secreting digestive enzymes, and detoxifying harmful substances are functions of the liver, but they are not primarily related to digestion.

4. A radioactive isotope has a half-life of 20 years. How many grams of a 6-gram sample will remain after 40 years?

• A. 8
• B. 6
• C. 3
• D. 1.5

Correct answer: C

Rationale: The half-life of a radioactive isotope is the time it takes for half of the original sample to decay. After each half-life period, half of the initial sample remains. In this case, after the first 20 years, half of the 6-gram sample (3 grams) will remain. After another 20 years (total of 40 years), half of the remaining 3 grams will remain, which is 1.5 grams. Therefore, 3 grams will be left after 40 years. Choice A is incorrect as it doesn't consider the concept of half-life and incorrectly suggests an increase in the sample. Choice B is incorrect as it assumes no decay over time. Choice D is incorrect as it miscalculates the remaining amount after two half-life periods.

5. What does Cast mean?

• A. A tool used for breaking bones
• B. Hard protective device applied to protect a broken bone
• C. A soft bandage
• D. An instrument used in surgery

Correct answer: B

Rationale: The correct answer is B. A cast is a hard protective device applied to protect a broken bone. Choice A is incorrect as a cast is not a tool used for breaking bones, but rather for supporting and protecting them. Choice C is incorrect as a cast is not a soft bandage but a rigid structure. Choice D is incorrect as a cast is not an instrument used in surgery, but a medical device used for bone support.
