1. A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?

• A. Losing weight can lower blood pressure, increase energy levels, and promote overall health.
• B. Society tends to treat overweight people unfairly.
• C. Members of the opposite sex are more interested in people who maintain a healthy weight.
• D. Losing weight is easy to do.

Correct answer: A

Rationale: Choice A is the correct answer as it provides a scientific argument supported by evidence. Losing weight has been shown to lower blood pressure, increase energy levels, and promote overall health. These are concrete health benefits that can be objectively measured and monitored. Choices B and C do not offer scientific justifications for weight loss but rather focus on societal perceptions and personal relationships. Choice D is incorrect as losing weight is not always easy and may require significant effort and lifestyle changes.

2. Water is capable of dissolving many substances that organisms need to carry out life functions. Which of the properties of water listed below is responsible for its ability to dissolve important nutrients like ionic salt compounds?

• A. adhesion
• B. cohesion
• C. high specific heat
• D. high polarity

Correct answer: D

Rationale: The property of water that is responsible for its ability to dissolve important nutrients like ionic salt compounds is its high polarity. Water is a polar molecule with a positive and negative end, which allows it to attract and surround individual ions from salt compounds, causing them to dissociate and dissolve in water. This property makes water an excellent solvent for various substances necessary for life functions. Adhesion refers to the ability of water molecules to stick to other substances, cohesion is the attraction between water molecules themselves, and high specific heat is the amount of heat energy required to raise the temperature of water. While these properties are important characteristics of water, they are not directly responsible for its ability to dissolve ionic salt compounds.

3. Which of the following defines the word 'unilateral'?

• A. Performed by one person
• B. Performed by many people
• C. Performed with precision
• D. Performed according to rules

Correct answer: A

Rationale: The correct answer is A: 'Performed by one person.' 'Unilateral' means something done by one person or group without the agreement of another. Choice B is incorrect as it suggests the opposite of what 'unilateral' means. Choice C is incorrect as it does not capture the essence of 'unilateral.' Choice D is incorrect as it is not directly related to the definition of 'unilateral.'

4. Which literary device is most prominent in Wilde's play?

• A. Irony
• B. Symbolism
• C. Metaphor
• D. Allusion

Correct answer: A

Rationale: The correct answer is 'Irony.' Irony is the most prominent literary device in Wilde's play, 'The Importance of Being Earnest,' as it pervades his critique of the upper class. Throughout the play, Wilde uses irony to highlight the absurdities and trivialities of the British aristocracy. The characters engage in witty and humorous dialogue filled with situational irony, verbal irony, and dramatic irony, exposing the superficiality and hypocrisy of the upper classes. Symbolism, metaphor, and allusion are present in the play but to a lesser extent compared to irony. While symbolism and metaphor are used to enhance the themes and characterizations, allusion is sparingly employed. However, it is the pervasive use of irony that sets the tone and drives Wilde's satire of the societal norms and values of the time.

5. What does the P-wave in an ECG correspond to?

• A. Atrial repolarization
• B. Depolarization of SA node
• C. Ventricular depolarization
• D. Ventricular repolarization

Correct answer: B

Rationale: The P-wave in an ECG represents the depolarization of the SA node and the atria, not atrial repolarization. Choice C, ventricular depolarization, is incorrect because the P-wave does not correspond to ventricular activity. Choice D, ventricular repolarization, is also incorrect as the P-wave does not depict ventricular repolarization. The correct interpretation is that the P-wave signifies the initiation of the electrical impulse at the SA node and subsequent atrial depolarization, making option B the correct answer.
