1. Multiply: 35 × 25 =
- A. 0.00875
- B. 0.0875
- C. 0.875
- D. 8.75
Correct answer: D
Rationale: To multiply 35 × 25, break it down into (30 + 5) × 25. Now distribute: (30 × 25) + (5 × 25) = 750 + 125 = 875. Therefore, 35 × 25 = 875. Choices A, B, and C are incorrect because they do not represent the correct result of multiplying 35 by 25. Choice A is 1000 times smaller than the correct answer, Choice B is 100 times smaller, and Choice C is 10 times smaller, making them all incorrect. The correct answer is Choice D, 8.75.
2. Which type of blood vessel carries blood back to the heart?
- A. Arteries
- B. Capillaries
- C. Veins
- D. Lymphatic vessels
Correct answer: C
Rationale: Veins are the blood vessels that carry deoxygenated blood back to the heart, except for the pulmonary veins which carry oxygenated blood from the lungs. Arteries carry oxygenated blood away from the heart. Capillaries facilitate the exchange of nutrients and gases between the blood and tissues but do not specifically carry blood back to the heart. Lymphatic vessels are part of the lymphatic system responsible for immune function and do not directly carry blood back to the heart. Therefore, the correct answer is veins.
3. Replete is best defined as being ___________.
- A. hardy
- B. quiet
- C. full
- D. sad
Correct answer: C
Rationale: Replete means filled to the utmost capacity or complete in every detail. Therefore, the best definition of replete from the given choices is 'full.' Choice A, 'hardy,' does not accurately reflect the meaning of replete. Choice B, 'quiet,' is unrelated to the definition of replete. Choice D, 'sad,' is also not synonymous with the term replete.
4. The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?
- A. A carpenter uses wood glue to fix a broken cabinet.
- B. A student buys a new notebook for upcoming classes.
- C. A chef sharpens knives before starting to cook.
- D. An athlete stretches before a game to avoid a potential injury.
Correct answer: D
Rationale: The correct analogy for the role of corrective lenses in helping aging eyes can be compared to an athlete stretching before a game. Just as stretching prepares an athlete's body to perform optimally and avoid injury during a game, corrective lenses help aging eyes adjust and focus properly due to the hardening and loss of elasticity in the eye lens. Choices A, B, and C do not align with the concept of preparing or adjusting to address a specific issue, unlike the use of corrective lenses for aging eyes.
5. Which of the following words or phrases fits best in the sentence below? Derek insists on working out daily ___________ his time is limited.
- A. despite
- B. due to
- C. even if
- D. whereas
Correct answer: A
Rationale: In the sentence, the word 'despite' is the best fit to convey the meaning that Derek insists on working out daily regardless of the limitation of his time. 'Despite' is used to show contrast or defiance against a situation or condition, making it the most suitable choice among the options provided. Choice B, 'due to,' would imply that Derek is working out daily because his time is limited, which is not the intended meaning of the sentence. Choice C, 'even if,' suggests a conditional scenario which does not align with the context of Derek's daily routine. Choice D, 'whereas,' introduces a comparison between two contrasting clauses, which does not fit the sentence where the focus is on Derek's persistence in working out despite limited time.
