1. The word 'massive' in line 4 is closest in meaning to?
- A. Dense
- B. Impressive
- C. Huge
- D. Unavoidable
Correct answer: C
Rationale: In the context of the passage, 'massive' is used to describe the size of the collision that formed the Moon, indicating something very large or huge. While 'dense' means closely compacted, 'impressive' means evoking admiration, 'huge' is the closest synonym to 'massive' in this context. 'Unavoidable' does not convey the same meaning as 'massive' in this sentence, making it incorrect.
2. What is the main idea of the passage about Toxins and Your Health?
- A. Environmental toxins may have dire health effects over time.
- B. Of three toxins studied, lead has the worst effect on health.
- C. Toxins may accumulate in the bones of older patients.
- D. Johns Hopkins University has discovered a new use for lead.
Correct answer: A
Rationale: The passage emphasizes the long-term effects of environmental toxins such as lead, pesticides, and mercury on brain health, particularly as individuals age. Dr. Brian Schwartz's quote highlights the link between environmental exposure and cognitive decline, framing the entire discussion around the potential health ramifications of such exposure over time. This clearly aligns with choice A, making it the main idea of the passage.
3. Which statement is not listed as a detail within the passage?
- A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
- B. The signal has a characteristic record called the electrocardiogram.
- C. The 'wave of excitation' starts at the SA node.
- D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.
Correct answer: A
Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.
4. What is the main idea of the passage about Sunny-Side Up?
- A. There are many positive effects of receiving direct exposure to sunlight.
- B. The negative impacts of sunlight should not be ignored.
- C. Vitamin D is integral for maintaining healthy bones and preventing diseases.
- D. Vitamin D is synthesized by our bodies in reaction to direct sunlight.
Correct answer: A
Rationale: The passage primarily discusses the various positive effects of sunlight exposure, particularly highlighting the benefits of vitamin D for bone health and the regulation of circadian rhythms. While it acknowledges the negative impacts of excessive sun exposure, the emphasis is on the positive aspects, making A the main idea of the passage.
5. The word 'track' as used in the last paragraph of the passage can best be defined as ___________.
- A. Keep a record of
- B. A new attitude
- C. Follow carefully
- D. A paved, circular path
Correct answer: D
Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.
