1. Which gland produces the hormone responsible for the 'fight-or-flight' response in stressful situations?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pancreas

Correct answer: C

Rationale: The correct answer is C: Adrenal gland. The hormone responsible for the 'fight-or-flight' response in stressful situations is produced by the adrenal gland. This hormone is called adrenaline (epinephrine) and is released in response to stress, preparing the body to either fight the stressor or flee from it. The other choices are incorrect because the thyroid gland primarily produces hormones that regulate metabolism, the pituitary gland produces various hormones that control other endocrine glands, and the pancreas produces insulin and glucagon to regulate blood sugar levels.

2. 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.

3. How does sunscreen protect the skin from harmful ultraviolet (UV) rays?

• A. By reflecting UV rays away from the skin
• B. By absorbing UV rays and converting them to heat
• C. By blocking UV rays completely
• D. By stimulating melanin production

Correct answer: B

Rationale: Sunscreen works by absorbing UV rays and converting them to heat. This mechanism helps to prevent the UV rays from penetrating the skin and causing damage such as sunburn, premature aging, and skin cancer. Reflecting UV rays away from the skin (option A) is not the primary function of sunscreen. While sunscreen does block UV rays, it does not do so completely (option C) as some UV rays may still penetrate the skin. Sunscreen does not stimulate melanin production (option D) as a means of protecting the skin from UV rays.

4. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

5. Which of the following lists the structures found beneath the rib in descending order?

• A. Nerve → Artery → Vein
• B. Vein → Nerve → Artery
• C. Vein → Artery → Nerve
• D. Artery → Nerve → Vein

Correct answer: C

Rationale: The correct order of structures found beneath the rib in descending order is Vein → Artery → Nerve. This sequence is important to remember for medical procedures like inserting a chest tube to ensure precision and avoid complications. Choice A is incorrect because the nerve is not typically the structure closest to the rib. Choice B is incorrect as the vein is usually closer to the rib than the nerve. Choice D is incorrect as the artery is usually closer to the rib than the nerve.
