• A. To entertain readers with facts about the rainforest.
• B. To inform readers about the deforestation of the Amazon.
• C. To persuade readers to visit the Amazon Rainforest.
• D. To criticize the farming practices in the Amazon.

Correct answer: B

Rationale: The author's primary purpose for writing the passage on the Amazon Rainforest is to inform readers about the deforestation and environmental challenges facing the Amazon. The passage provides detailed information about the Amazon Rainforest, its biodiversity, the impact of deforestation on the environment, and the dangers associated with the destruction of the rainforest. Choice A is incorrect because the author's goal is not to entertain but to educate readers.

• A. Through a contractile ring
• B. Via a cell plate
• C. Both methods
• D. None of the above

Correct answer: A

Rationale: Animal cells divide through a contractile ring made of actin and myosin filaments. The ring contracts, pinching the cell membrane in the middle to form two daughter cells. Plant cells use a cell plate due to their rigid cell walls, making choices B and C incorrect. Choice D is incorrect as animal cells do use the contractile ring method for division.

3. What is the primary function of the liver?

• A. Detoxifying harmful substances
• B. Producing bile
• C. Producing insulin
• D. Storing glycogen

Correct answer: A

Rationale: The primary function of the liver is to detoxify harmful substances in the blood. While the liver also produces bile, which aids in digestion, stores glycogen for energy storage, and participates in metabolism, its main and essential function is detoxification. Producing insulin is mainly attributed to the pancreas, not the liver.

• A. 14.12
• B. 0.234
• C. 7.64

Correct answer: D

Rationale: To find the result of multiplying 7.2 by 0.34, multiply these two numbers: 7.2 x 0.34 = 2.448. The correct answer is 2.448. Choice A, 14.12, is incorrect as it seems to be the sum of the two numbers. Choice B, 0.234, is incorrect as it is much smaller than the expected result. Choice C, 7.64, is incorrect as it is the result of adding the two numbers rather than multiplying them.

• D. Divulged.

Correct answer: B

The other options do not accurately capture the implications of "exposed" in relation to toxic substances, making B the correct choice.
