1. Based on this passage, what can the reader infer about the advice physicians will give their pregnant patients about coffee consumption?

• A. Almost all of them will advise women to stop drinking any caffeine until after the baby is born.
• B. The majority will ignore the study altogether and continue to advise caffeine in moderation as before.
• C. All of them will demand additional research be done before they change what they tell their patients.
• D. Some will continue to make their normal recommendations about caffeine, while others will be more cautious than before.

Correct answer: D

Rationale: The passage implies that there is variability in physician responses to the study about caffeine consumption. Some doctors may continue their standard recommendations, while others might advise more caution based on the new evidence. Therefore, option D reflects this variability in professional opinions and is the correct inference.

2. Choose the best summary of the passage about High Fructose Corn Syrup.

• A. After extensive studies, scientists recommend removing HFCS from grocery products.
• B. A recent study on rats confirms suspicions that HFCS contributes to unhealthful weight gains.
• C. Until more research is done, using HFCS is preferable to replacing it with refined sugar.
• D. Avoiding HFCS can have immediate, healthful results on overweight patients, as suggested by the AMA.

Correct answer: B

Rationale: The best summary of the passage is choice B. The passage discusses concerns about the impact of high fructose corn syrup (HFCS) on health, particularly its link to obesity. It mentions a recent study on rats that confirms suspicions about HFCS contributing to unhealthful weight gains. Choices A, C, and D are incorrect as they introduce recommendations or implications not explicitly mentioned in the passage. Choice A goes beyond the information by stating that scientists recommend removing HFCS from grocery products, choice C suggests that using HFCS is preferable until more research is done, and choice D implies immediate healthful results on overweight patients by avoiding HFCS, as suggested by the AMA, which is not supported by the passage.

3. What is the best summary of the passage?

• A. Electric currents within the body are due to electrostatic charges set off by the heart. Medical staff are trained to recognize any abnormalities within the heart.
• B. Every individual has unique electric currents on the surface of the body. The ECG measures and records these electric currents.
• C. The ECG systematically and rather quickly measures the stages at which the 'wave of excitation' occurs within the heart and records them. This wave has three distinct steps that spread from the SA node to the AV node.
• D. The ECG measures the electric currents within the body. These currents are detected on the surface of the body when the body is connected to an amplifier.

Correct answer: C

Rationale: The correct summary of the passage is option C. The passage explains how the ECG systematically measures and records the 'wave of excitation' that occurs within the heart in three distinct steps, spreading from the SA node to the AV node. This summary effectively captures the main focus of the passage. Option A is incorrect because it only mentions the detection of electric currents in the body and recognizing abnormalities by medical staff, missing the key information about the 'wave of excitation' and its stages. Option B is incorrect as it focuses solely on the measurement and recording of unique electric currents on the body's surface, neglecting the specific process described in the passage. Option D is also incorrect as it provides a general description of how the ECG measures electric currents without emphasizing the specific stages of the 'wave of excitation' as detailed in the passage.

4. The passage lists all of these benefits of omega-3s EXCEPT ___________.

• A. Reduced blood pressure
• B. Less risk of diabetes
• C. Improved memory
• D. Alleviated depression

Correct answer: B

Rationale: The passage mentions reduced blood pressure, improved memory, and alleviated depression as potential benefits of omega-3s but does not mention a reduced risk of diabetes.

5. What is implied about the rainforest's role in global climate?

• A. The rainforest has little impact on the climate.
• B. The rainforest plays a crucial role in regulating the climate.
• C. The rainforest is mainly important for biodiversity.
• D. The rainforest's destruction has no global consequences.

Correct answer: B

Rationale: The rainforest plays a crucial role in regulating the global climate by absorbing carbon dioxide. The extract highlights the fact that trees take in carbon dioxide and give off oxygen. When trees are cut down, the amount of carbon dioxide increases, contributing to global warming. This emphasizes the significant impact of rainforests on the climate. Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.
