1. What is the central idea conveyed in the passage?

• A. David Foster Wallace's Infinite Jest is the holy grail of modern literature.
• B. Infinite Jest is a page-turner.
• C. David Foster Wallace wrote Infinite Jest.
• D. Infinite Jest is a modern classic for good reason and everybody should read it.

Correct answer: D

Rationale: The passage describes Infinite Jest as a modern classic that holds significant value, indicating that it is highly recommended for everyone to read it. Choice A focuses solely on the praise of the book without emphasizing the recommendation to read it. Choice B, mentioning it as a page-turner, does not capture the essence of it being a modern classic that everyone should read. Choice C is a factual statement about the authorship but does not encompass the main point that the book is a modern classic that deserves to be read by all.

2. Half of a circular garden with a radius of 11.5 feet needs weeding. Find the area in square feet that needs weeding. Round to the nearest hundredth. Use 3.14 for π.

• A. 207.64
• B. 415.27
• C. 519.08
• D. 726.73

Correct answer: B

Rationale: The area of a circle is given by the formula A = π × r², where r is the radius. Since only half of the garden needs weeding, we calculate half the area. Using the given value of π (3.14) and a radius of 11.5 feet: A = 0.5 × 3.14 × (11.5)² A = 0.5 × 3.14 × 132.25 A = 0.5 × 415.27 A = 207.64 square feet. Thus, the area that needs weeding is approximately 207.64 square feet, making option B the correct answer. Choice A (207.64) is incorrect as it represents the total area of the circular garden, not just half of it. Choice C (519.08) and Choice D (726.73) are also incorrect as they do not reflect the correct calculation for finding the area of half the circular garden.

3. Which of the following produces the first heart sound ('lub')?

• A. The closing of the aortic and pulmonary valves
• B. The closing of the tricuspid and mitral valves
• C. The opening of the aortic and pulmonary valves
• D. The opening of the tricuspid and mitral valves

Correct answer: B

Rationale: The correct answer is B. The first heart sound, known as the 'lub' sound, is produced by the closure of the tricuspid and mitral valves, which are the atrioventricular valves. This sound marks the beginning of systole in the cardiac cycle. Choice A, the closing of the aortic and pulmonary valves, is incorrect as these valves produce the second heart sound ('dub'). Choice C, the opening of the aortic and pulmonary valves, is incorrect because the first heart sound occurs during ventricular contraction (systole). Choice D, the opening of the tricuspid and mitral valves, is incorrect as the 'lub' sound is associated with the closure, not the opening, of these valves.

4. Which of the following best describes the term monochromatic?

• A. having one color
• B. having many parts
• C. having a lot of time
• D. having too much heat

Correct answer: A

Rationale: The term 'monochromatic' refers to something that has only one color. Choice A, 'having one color,' is the correct description for monochromatic. Choices B, C, and D are incorrect as 'monochromatic' does not mean 'having many parts,' 'having a lot of time,' or 'having too much heat.' Monochromatic specifically conveys the idea of consisting of or using only one color, making Choice A the correct answer.

5. Which of the following organs is responsible for filtering waste from the blood?

• A. Liver
• B. Kidneys
• C. Pancreas
• D. Heart

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.
