1. If all of the following sentences appeared in the same paragraph, which sentence would be irrelevant?
- A. I had been doing yoga at least three times a week for the past year.
- B. At first, I walked and ran, though really it was more walking than running.
- C. I had never run a 5k race before, but I decided to try and gave myself six weeks to train for it.
- D. Each day I was able to run a bit further and a bit faster.
Correct answer: A
Rationale: The sentence about doing yoga is irrelevant to the topic of training for a 5k race. The focus of the paragraph is on the process of preparing for the race through running and training, making sentence A unrelated as it discusses a different physical activity.
2. Alan currently weighs 200 pounds, but he wants to lose weight to get down to 175 pounds. What is the difference in kilograms? (1 pound is approximately equal to 0.45 kilograms.)
- A. 9 kg
- B. 11.25 kg
- C. 78.75 kg
- D. 90 kg
Correct answer: B
Rationale: The difference between Alan's current weight of 200 pounds and his goal weight of 175 pounds is 25 pounds (200 pounds - 175 pounds). To convert pounds to kilograms, you multiply the number of pounds by 0.45 (not divide by 2.2). Thus, 25 pounds is approximately 11.25 kilograms (25 pounds x 0.45). Therefore, the difference in kilograms is 11.25 kg. Choice A is incorrect because it miscalculates the conversion. Choices C and D are significantly higher values and do not reflect the correct conversion from pounds to kilograms.
3. How many pounds are in 1 ton?
- A. 1000 pounds
- B. 2000 pounds
- C. 1500 pounds
- D. 2500 pounds
Correct answer: B
Rationale: The correct answer is B: 2000 pounds. A ton is equivalent to 2000 pounds. This is a standard conversion in the imperial system of measurement. Choice A, 1000 pounds, is incorrect as it represents half a ton. Choice C, 1500 pounds, and Choice D, 2500 pounds, are also incorrect as they do not match the correct conversion of 1 ton to 2000 pounds.
4. Which of the following enzymes unwinds the double-stranded DNA during replication?
- A. Helicase
- B. Ligase
- C. Nuclease
- D. Polymerase
Correct answer: A
Rationale: Helicase is the enzyme responsible for unwinding the double-stranded DNA during replication by breaking the hydrogen bonds between the base pairs. This process creates the replication fork where DNA polymerase can then synthesize new DNA strands. Ligase functions to join Okazaki fragments on the lagging strand, not unwind DNA. Nuclease is involved in DNA repair by removing damaged DNA segments. Polymerase is responsible for synthesizing new DNA strands based on the existing template strands, not for unwinding the DNA.
5. Which element is found in water and is crucial for biological functions like nerve impulses and muscle contraction?
- A. Sodium
- B. Potassium
- C. Calcium
- D. Magnesium
Correct answer: A
Rationale: The correct answer is Sodium. Sodium is found in water and is crucial for biological functions like nerve impulses and muscle contraction. It plays a key role in maintaining electrolyte balance and transmitting nerve impulses, affecting both muscles and nerves. Potassium (Choice B), although essential for nerve function and muscle control, is not typically found in water. Calcium (Choice C) is important for bone health and muscle function, but it is not the element found in water. Magnesium (Choice D) is also essential for various biological functions but is not the element commonly found in water.
