1. The 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: Corticosteroids, produced by the adrenal cortex, primarily function to control blood pressure and electrolyte balance. One of the key corticosteroids, aldosterone, plays a crucial role in regulating sodium and potassium levels in the body. This regulation is essential for maintaining blood pressure and electrolyte balance. Choices A, C, and D are incorrect because corticosteroids do not primarily regulate insulin sensitivity and blood sugar levels, stimulate the immune system and inflammatory response, or promote growth and development during puberty. While corticosteroids can have effects on insulin sensitivity, immune response, and growth, their major role is in maintaining blood pressure and electrolyte balance.

2. Which hormone deficiency can lead to stunted growth and developmental delays in children?

• A. Estrogen
• B. Testosterone
• C. Growth hormone
• D. Insulin

Correct answer: C

Rationale: The correct answer is C, Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in children. A deficiency in growth hormone can lead to stunted growth and developmental delays. Estrogen and testosterone are sex hormones that do not directly influence growth in the same way as growth hormone. Insulin primarily regulates blood sugar levels and is not the primary hormone responsible for growth and development in children.

3. What is the definition of the word 'haunt' in the following passage? 'From that time forward, Mr. Utterson began to haunt the door in the by street of shops.'

• A. To levitate
• B. To constantly visit
• C. To terrorize
• D. To daunt

Correct answer: B

Rationale: 'Haunt' in this context means to visit a place frequently or persistently, which aligns with Mr. Utterson's actions of regularly going to the door in the by street of shops. The other choices are incorrect because 'levitate' means to rise or float in the air, 'terrorize' means to cause extreme fear, and 'daunt' means to make someone feel intimidated or apprehensive, none of which accurately reflect the meaning of 'haunt' in this context.

4. How is the density of a substance calculated?

• A. Mass / Volume
• B. Volume / Mass
• C. Mass x Volume
• D. None of the above

Correct answer: A

Rationale: The density of a substance is calculated by dividing the mass of the substance by its volume. The formula for density is Density = Mass / Volume. This calculation allows us to determine how much mass is present in a given volume of a substance, making option A the correct choice. Choice B (Volume / Mass) is incorrect because density is defined as mass per unit volume, so mass should be the numerator. Choice C (Mass x Volume) is incorrect as this would result in a different unit of measurement and not represent density. Choice D (None of the above) is incorrect as there is a specific formula for calculating density, which is mass divided by volume.

5. Which of the following sentences uses the word 'smart' with a negative connotation, rather than a positive connotation or simply the word's denotation?

• A. Eliot's teacher said he was not quite gifted, but too smart for a general class.
• B. Eliot was smart to have studied the day before the test; he got a good grade.
• C. Eliot was identified by his teacher as one of the smart students in her classes.
• D. Eliot got into trouble when he gave a smart answer to his teacher's question.

Correct answer: D

Rationale: In sentence D, the word 'smart' is used with a negative connotation as it describes Eliot getting into trouble for giving a smart answer to his teacher's question. This implies that being smart in this context led to a negative consequence. Choices A, B, and C use 'smart' in a positive or neutral light, highlighting intelligence or wise decisions without any negative implications.
