1. What is the best definition of the underlined word in the selection below, taken from the third paragraph of the passage? 'You should try to be aware of your consumption of water and energy.'

• A. Using the greatest amount
• B. Illness of the lungs
• C. Using the least amount
• D. Depletion of goods

Correct answer: D

Rationale: In this context, 'consumption' refers to the use or depletion of resources like water and energy. It is not about using the greatest amount (choice A) or the least amount (choice C) but about being mindful of how much you use to avoid depletion. 'Illness of the lungs' (choice B) is completely unrelated to the context of resource conservation discussed in the passage.

2. What is the waste product of protein digestion?

• A. Glucose
• B. Amino acids
• C. Fatty acids
• D. Ammonia

Correct answer: D

Rationale: The waste product of protein digestion is ammonia. Protein digestion breaks down proteins into amino acids, and during this process, ammonia is produced. Ammonia is toxic and needs to be converted into urea in the liver for excretion via urine. Glucose is a product of carbohydrate digestion, amino acids are building blocks of proteins, and fatty acids are the end products of fat digestion. Therefore, the correct answer is ammonia.

3. Which of the following is not identified as a difference between the two authors?

• A. Malory wrote prose, while Tennyson wrote poetry.
• B. Malory wrote during the medieval era, while Tennyson wrote during the Victorian era.
• C. Malory was more focused on heroism and morality, while Tennyson was more focused on nature and elegy.
• D. Malory wrote stories about Gareth, Tristan, and Isolde, while Tennyson focused only on Arthur, Lancelot, and Guinevere.

Correct answer: D

Rationale: The passage explicitly mentions that Malory included chapters on knights such as Lancelot and Gareth, and he discussed the relationships between Tristan and Isolde, and Lancelot and Guinevere. This shows that Malory did focus on a wider range of characters beyond just Arthur, Lancelot, and Guinevere. Therefore, the difference mentioned in option D is not accurate as it is identified in the passage that Malory did write stories about Gareth, Tristan, and Isolde. Choices A, B, and C are all correctly identified as differences between the two authors based on the passage provided.

4. In an oxidation reaction,

• A. an oxidizing agent gains electrons.
• B. an oxidizing agent loses electrons.
• C. a reducing agent gains electrons.
• D. a reducing agent loses electrons.

Correct answer: B

Rationale: In an oxidation reaction, the substance being oxidized loses electrons, not gains them. An oxidizing agent is responsible for causing oxidation in another substance by accepting electrons, hence it undergoes reduction and loses electrons. Therefore, the correct statement is 'an oxidizing agent loses electrons,' making choice B the correct answer. Choices A, C, and D are incorrect because in an oxidation reaction, the oxidizing agent does not gain electrons, a reducing agent does not gain electrons, and a reducing agent does not lose electrons.

5. Which of the following structures in the respiratory system is responsible for gas exchange?

• A. Trachea
• B. Alveoli
• C. Bronchi
• D. Diaphragm

Correct answer: B

Rationale: The correct answer is B: Alveoli. The alveoli in the lungs are responsible for gas exchange. They have a thin membrane that allows for the exchange of oxygen and carbon dioxide between the air in the lungs and the blood in the capillaries surrounding them. This process is essential for respiration, providing oxygen to the body's tissues and removing carbon dioxide, a waste product of cellular metabolism. Choices A, C, and D are incorrect. The trachea is a passageway that carries air to and from the lungs but is not directly involved in gas exchange. Bronchi are airway passages that further divide into smaller bronchioles leading to the alveoli but do not perform gas exchange themselves. The diaphragm is a muscle involved in the breathing process by aiding in inhalation and exhalation, but it is not the structure responsible for gas exchange in the respiratory system.
