1. Xan was worried about the epidemic she heard about on the news. In the word 'epidemic,' the prefix 'epi-' most closely means:

• A. Badly
• B. On
• C. A lot
• D. A little

Correct answer: B

Rationale: The correct answer is 'B: On.' The prefix 'epi-' means 'on' or 'upon,' as seen in the word 'epidemic.' An epidemic refers to a situation where a disease spreads rapidly and affects many people. Choice 'A: Badly' is incorrect as it does not accurately represent the meaning of the prefix 'epi-.' Choices 'C: A lot' and 'D: A little' are also incorrect as they are not related to the prefix 'epi-' in the context of the word 'epidemic.'

2. Which of the following is responsible for carrying electrical impulses in the nervous system?

• A. Platelets
• B. Neurons
• C. Red blood cells
• D. White blood cells

Correct answer: B

Rationale: Neurons are the correct answer as they are specialized cells in the nervous system that transmit electrical impulses throughout the body. Neurons have structures like axons and dendrites that enable the transmission of electrical signals. Platelets are responsible for blood clotting, red blood cells carry oxygen, and white blood cells are part of the immune system; however, none of these cell types play a role in carrying electrical impulses in the nervous system.

3. Which structure in the body is responsible for producing testosterone?

• A. Adrenal glands
• B. Pituitary gland
• C. Testes
• D. Pancreas

Correct answer: C

Rationale: The correct answer is C: Testes. The testes are responsible for producing testosterone, the hormone that plays a crucial role in male secondary sexual characteristics such as facial hair, deepening of the voice, and muscle development. The adrenal glands primarily produce cortisol and aldosterone, not testosterone. The pituitary gland regulates hormone production in various glands, including the testes, but it does not directly produce testosterone. The pancreas is responsible for producing insulin and glucagon to regulate blood sugar levels, not testosterone.

4. What is the name of the microscopic filtering unit within the kidney responsible for waste removal and blood volume regulation?

• A. Nephron
• B. Ureteric bud
• C. Renal pyramid
• D. Glomerulus

Correct answer: A

Rationale: The correct answer is A: Nephron. The nephron is the functional unit of the kidney responsible for waste removal and blood volume regulation. It is composed of several structures, including the glomerulus, Bowman's capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct. The other options mentioned in the question (ureteric bud, renal pyramid, and glomerulus) are not the correct names for the microscopic filtering unit within the kidney. The glomerulus is a part of the nephron, specifically responsible for ultrafiltration in the initial stage of urine formation.

5. Based upon the contextual evidence provided in the passage above, what is the meaning of the term enterprise in the third paragraph?

• A. Company
• B. Courage
• C. Game
• D. Cause

Correct answer: A

Rationale: In the third paragraph, the term 'enterprise' is used in the context of a group of travelers embarking on a journey together. In this context, 'enterprise' refers to a company or a group of people rather than courage, game, or cause. The word 'enterprise' is commonly used to denote a business organization or company, aligning with the idea of a group traveling together for a common purpose. 'Courage' and 'cause' do not fit the context of the travelers' journey, and 'game' is unrelated to the activities described in the passage.
