Rationale: This sentence uses a simile, comparing the child's speed to a cheetah's.

3. Which phrase best describes the tone of the passage?

• A. Humorous and lighthearted
• B. Suspenseful and mysterious
• C. Objective and informative
• D. Critical and judgmental

4. Which of the following is an example of an unsaturated fatty acid?

• A. Stearic acid
• B. Palmitic acid
• C. Oleic acid
• D. Butyric acid

Correct answer: C

Rationale: Oleic acid is an unsaturated fatty acid, containing at least one double bond in its hydrocarbon chain. The other choices are saturated fatty acids.

5. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

6. What is the primary difference between ionic and metallic bonding?

• A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer.
• B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
• C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
• D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.

Correct answer: B

Rationale: Ionic bonds form discrete molecules, while metallic bonds form extended structures. Ionic bonds involve complete electron transfer between specific atoms, resulting in discrete molecules. Metallic bonds involve a "sea" of delocalized electrons shared across all metal atoms, leading to strong, non-directional bonding throughout the entire material.
