1. Which of the following is a correct thesis statement?

Correct answer: C

Rationale: Choice C is the correct thesis statement because it presents a clear argument or claim, making it a strong thesis statement. The thesis statement asserts President Perez as the greatest leader based on her proposal of a universal income to eradicate inequity among citizens. This statement sets a specific focus and direction for the essay or discussion that follows. Choices A, B, and D do not function as thesis statements. Choice A provides a descriptive event but lacks a clear argument. Choice B highlights an achievement but does not establish a central claim. Choice D mentions an interview but does not present a focused argument as required in a thesis statement.

2. How many micrograms are in 0.15 mg?

Correct answer: A

Rationale: To convert milligrams to micrograms, you need to multiply by 1000 because there are 1000 micrograms in 1 milligram. Therefore, 0.15 mg is equal to 150 mcg. Choice B (15 mcg) is incorrect as it represents the conversion of 0.015 mg to mcg. Choice C (1.5 mcg) is incorrect as it represents the conversion of 0.0015 mg to mcg. Choice D (1500 mcg) is incorrect as it represents the conversion of 1.5 mg to mcg. So, the correct answer is 150 mcg, a conversion often used in medical dosing.

3. A homeowner has hired two people to mow his lawn. If person A is able to mow the lawn in 2 hours by herself and person B is able to mow the lawn in 3 hours by himself, what is the amount of time it would take for both person A and B to mow the lawn together?

Correct answer: C

Rationale: To find the combined work rate, you add the individual work rates: 1/2 + 1/3 = 5/6. This means that together, they can mow 5/6 of the lawn per hour. To determine how long it would take for both A and B to mow the entire lawn, you take the reciprocal of 5/6, which gives you 6/5 or 1.2 hours. Therefore, it would take 1.2 hours for person A and person B to mow the lawn together. Choice A (5 hours) is incorrect because it does not consider the combined efficiency of both workers. Choice B (2.5 hours) is incorrect as it does not reflect the correct calculation based on the combined work rates of the two individuals. Choice D (1 hour) is incorrect as it doesn't consider the fact that the combined rate is less than the individual rate of person A alone, thus taking longer than 1 hour.

4. What function do hydrophobic proteins often provide in the body?

Correct answer: B

Rationale: Hydrophobic proteins are known for their ability to repel water and are often involved in providing structural support in cells and tissues. They help maintain the structural integrity and shape of cell membranes, organelles, and other cellular components. Choice A, digestive enzymes, typically consist of hydrophilic proteins that interact with water and substrates to facilitate digestion. Choice C, carrying oxygen molecules, is a function commonly associated with specific proteins like hemoglobin. Choice D, storing energy, is usually performed by proteins like enzymes involved in energy storage and release, such as glycogen phosphorylase.

5. Which of the following is NOT a characteristic of a chemical reaction?

Correct answer: C

Rationale: A change in color is not always a characteristic of a chemical reaction. While some chemical reactions may result in a change in color, it is not a universal characteristic of all chemical reactions. The formation of new substances, release or absorption of energy, and change in temperature are commonly associated with chemical reactions. Therefore, the correct answer is C, as it does not always occur in every chemical reaction.
