1. The adaptive immune system has two main branches: humoral and cell-mediated immunity. Which type of immune cell is primarily responsible for antibody production?

• A. Helper T cells
• B. Cytotoxic T cells
• C. B cells
• D. Natural killer cells

Correct answer: C

Rationale: B cells are primarily responsible for antibody production in the adaptive immune system. When activated, B cells differentiate into plasma cells, which are specialized to produce antibodies. Helper T cells play a crucial role in activating B cells, but they do not directly produce antibodies. Cytotoxic T cells are involved in cell-mediated immunity by killing infected cells, while natural killer cells are part of the innate immune system and target virus-infected and cancerous cells. Therefore, the correct answer is C (B cells) as they are directly involved in the production of antibodies, essential for humoral immunity.

2. Which of the following is NOT a function of the lymphatic system?

• A. Removing substances from the blood.
• B. Releasing hormones.
• C. Combating disease.
• D. Maintaining tissue fluid balance.

Correct answer: B

Rationale: The correct answer is B. Releasing hormones is not a function of the lymphatic system. The lymphatic system plays crucial roles in removing substances from the blood, combating disease through the production of immune cells, and maintaining tissue fluid balance by circulating lymph. Releasing hormones is primarily the function of endocrine glands, not the lymphatic system.

3. While researching Chomsky's Jewish heritage, Teddy wants to research traditional Judaism. Which section of the library would most likely contain the most relevant information?

• A. 100
• B. 200
• C. 300
• D. 900

Correct answer: B

Rationale: The correct answer is B: '200.' According to the Dewey Decimal System, religion falls under section 200. Traditional Judaism research aligns with religious studies, making section 200 the most suitable for finding relevant information. Choices A, C, and D do not directly relate to religious topics and are therefore less likely to contain information on traditional Judaism.

4. Which division of the peripheral nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling voluntary muscle movements?

• A. Somatic nervous system
• B. Autonomic nervous system
• C. Sympathetic nervous system
• D. Parasympathetic nervous system

Correct answer: A

Rationale: The correct answer is the somatic nervous system. The somatic nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, allowing for voluntary muscle movements. The autonomic nervous system, sympathetic nervous system, and parasympathetic nervous system are not involved in voluntary muscle movements. Instead, they regulate involuntary functions of the body such as heart rate, digestion, and breathing. Therefore, choices B, C, and D are incorrect as they are not associated with voluntary muscle movements.

5. Which of the following guides would be the best for Raul?

• A. A Beginner's Guide to Giza (2015)
• B. The Life of Zahi Hawass (2014)
• C. A History of Hieroglyphics (2013)
• D. Who Built the Great Pyramids? (2015)

Correct answer: D

Rationale: The best guide for Raul would be 'Who Built the Great Pyramids?' as it focuses on the construction of the pyramids, providing detailed research on the topic. Choices A, B, and C are less relevant as they do not specifically address the construction of the pyramids. Choice A is about Giza in general, Choice B is a biography, and Choice C is about hieroglyphics, none of which directly relate to the construction of the pyramids.
