1. 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.
2. Which of the following statements is an opinion related to Hypertension?
- A. Obese people are at risk for hypertension.
- B. Losing weight can decrease blood pressure.
- C. Older people must pay attention to their blood pressure.
- D. Blurred vision or dizziness may be a sign of hypertension.
Correct answer: C
Rationale: A statement of fact can be proved or checked. A statement of opinion is what someone thinks or believes. In this case, statements A, B, and D could be proved scientifically, but statement C is simply a suggestion. While it is advisable for older people to monitor their blood pressure due to the increased risk associated with aging, the statement itself is an opinion because it suggests what older people 'must' do, which is a subjective viewpoint rather than a verifiable fact. Statements A, B, and D provide factual information supported by scientific evidence, making them statements of fact rather than opinion.

4. Identify the overall tone of the essay about Aromatherapy.
- A. Congratulatory.
- B. Uncertain.
- C. Annoyed.
- D. Distressed.
Correct answer: B
Rationale: The tone of the essay is uncertain, as the author questions the validity of aromatherapy based on the study's results. The phrasing "does not necessarily prove that aromatherapy is worthless" indicates a hesitance to fully endorse or dismiss its value. This ambiguity throughout the passage reinforces the uncertain tone, aligning it with choice B.

- A. People of South American or African descent may be prone to sickle-cell anemia.
- B. Symptoms of sickle-cell anemia may include sudden occurrences of extreme abdominal and back pain.
- C. The red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes.
- D. Vitamin and mineral deficiencies may result in some anemia.
Correct answer: D
Rationale: The correct answer is D because the passage does not mention anything about vitamin and mineral deficiencies in relation to sickle-cell anemia. Choice A is incorrect as the passage specifies that sickle-cell anemia is more common among people of South American or African descent. Choice B is correct as the passage states that symptoms of sickle-cell anemia can include sudden occurrences of extreme abdominal and back pain. Choice C is correct as the passage describes that the red blood cells of sickle-cell patients are unusually shaped, forming crescent or sickle shapes. The passage does not discuss any relationship between vitamin and mineral deficiencies and sickle-cell anemia, making choice D the correct option.
