1. Which of the following sentences uses figurative language?

• A. The scientist conducted an experiment.
• B. The child ran like a cheetah.
• C. The book contained many pages.
• D. The teacher explained the concept clearly.

Correct answer: B

Rationale: Choice B is the correct answer as it uses a simile, comparing the child's speed to that of a cheetah. Figurative language uses words or expressions with a meaning that is different from the literal interpretation, making the sentence more vivid and imaginative. In this case, the simile enhances the description of the child's speed by likening it to the swift and agile movement of a cheetah. Choices A, C, and D do not use figurative language. Option A is a straightforward statement about a scientist conducting an experiment without any figurative elements. Option C is a factual statement about a book having many pages without any figurative language. Option D is a clear explanation by a teacher without any figurative language present.

2. What is the name of the white blood cells that attack foreign invaders?

• A. Phagocytes
• B. Lymphocytes
• C. Platelets
• D. Red blood cells

Correct answer: A

Rationale: Phagocytes are a type of white blood cell that plays a crucial role in the immune system by engulfing and digesting foreign invaders such as bacteria, viruses, and other harmful substances. They are part of the body's innate immune response and are essential for protecting the body against infections. Lymphocytes, on the other hand, are another type of white blood cell involved in the adaptive immune response, producing antibodies, and coordinating immune responses. Platelets are cell fragments involved in blood clotting, while red blood cells are responsible for carrying oxygen to tissues. Therefore, the correct answer is Phagocytes (Choice A) because they are specifically tasked with attacking and destroying foreign invaders in the body, distinguishing them from the other choices which have different functions within the immune system.

3. What is a secondary argument the author makes?

• A. Devices such as the iPad or Kindle are better than books because they have multiple uses.
• B. Books are still important to have while waiting for an appointment or taking a flight.
• C. Printed encyclopedias are still used and more convenient than using the Internet.
• D. With technology, there will soon be no need for stories.

Correct answer: A

Rationale: The secondary argument made by the author is that devices such as the iPad and Kindle are superior to printed books because they offer multiple functions beyond just reading. The author mentions that these devices have qualities similar to a computer and can be used for much more than just reading, making them a more versatile option compared to traditional books. Choice B is incorrect because the author does not emphasize the importance of books for specific situations like waiting for appointments or flights. Choice C is incorrect as the author does not compare printed encyclopedias to the Internet. Choice D is incorrect as the author does not suggest that technology will eliminate the need for stories; instead, they focus on the transition from printed books to electronic devices for reading.

4. What is the control, if any, in this experiment?

• A. There is no control in this experiment
• B. The control is the water
• C. The control is the diet soda
• D. The control is the amount of sunlight provided to the plants

Correct answer: B

Rationale: The correct answer is B: 'The control is the water.' In a scientific experiment, the control group is used as a baseline comparison to evaluate the effects of the variables being tested. Here, the water serves as the control group against which the effects of other substances like diet soda or different amounts of sunlight can be compared. Choice A is incorrect as every experiment should have a control group for comparison. Choice C and D are incorrect as they are not the standard control in this scenario.

5. During antibiotic use, bacteria can evolve resistance. This is an example of:

• A. Coevolution (two species influencing each other's evolution)
• B. Convergent evolution (unrelated organisms evolving similar traits)
• C. Macroevolution (large-scale evolutionary change)
• D. Artificial selection acting on a natural process

Correct answer: D

Rationale: The process of bacteria evolving resistance to antibiotics due to the selective pressure exerted by the antibiotics is an example of artificial selection (human intervention selecting for certain traits) acting on a natural process (bacterial evolution). Antibiotic use creates a selective pressure that favors the survival and reproduction of bacteria with resistance traits, leading to the evolution of antibiotic-resistant strains. - Coevolution (option A) refers to the influence of two species on each other's evolution, which is not the case in the scenario described in the question. - Convergent evolution (option B) involves unrelated organisms evolving similar traits due to similar environmental pressures, which is not directly applicable to the situation of bacteria evolving resistance to antibiotics. - Macroevolution (option C) refers to large-scale evolutionary changes over long periods, which is not specifically demonstrated in the context of bacteria evolving resistance during antibiotic use.
