1. What is the meaning of the word supplementation as used in the second paragraph?

A. Extra
B. Organization
C. Attachment
D. Revision

Correct answer: A

Rationale: The term "supplementation" refers to the addition of nutrients to the diet. In the context of the passage, it highlights the need for seniors to receive extra nutrients such as calcium and vitamin D beyond what they typically consume in their diets. This reflects the understanding that seniors may not get sufficient nutrition solely from their regular meals, supporting option A.

2. 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.

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. What conclusion can a reader draw from this passage?

A. It is advisable to choose unsaturated fats over saturated fats.
B. Saturated fats are more calorically dense than unsaturated fats.
C. Trans fats are more calorically dense than saturated fats.
D. Unsaturated fats are mostly found in animal products.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.

5. What is the author’s primary purpose in writing the essay about Sunny-Side Up?

A. To persuade.
B. To reflect.
C. To entertain.
D. To inform.

Correct answer: D

Rationale: The author's primary purpose is to inform readers about the benefits of sunlight, including its role in vitamin D synthesis and other health benefits. While the passage does advocate for sunlight exposure, the primary aim is to provide information rather than persuade or entertain, making D the most accurate choice.
