1. Sally eats 3/5 of her lunch. John eats 75%. Who ate more?

• A. John
• B. Sally
• C. Both the same
• D. Neither

Correct answer: A

Rationale: To compare, convert both to decimals or percentages: Sally ate 3/5, which is 0.6 or 60%. John ate 75%. Since 75% is greater than 60%, John ate more than Sally. Thus, the correct answer is A. John. Choice B is incorrect because Sally ate a smaller percentage of her lunch compared to John. Choice C is incorrect as the percentages consumed are different. Choice D is incorrect as one of them ate more.

2. Which of the following endocrine system glands releases the thyrotrophic-releasing hormone, growth hormone-releasing hormone, and gonadotropin-releasing hormone?

• A. Thymus
• B. Pituitary gland
• C. Pineal gland
• D. Hypothalamus

Correct answer: D

Rationale: The correct answer is D, the Hypothalamus. The hypothalamus is responsible for releasing key hormones like thyrotrophic-releasing hormone, growth hormone-releasing hormone, and gonadotropin-releasing hormone. These hormones play essential roles in regulating various body functions by influencing the activities of other endocrine glands. Choices A, B, and C are incorrect because the thymus is involved in immune function, the pituitary gland releases different hormones, and the pineal gland primarily produces melatonin, not the hormones mentioned in the question.

3. The ETIOLOGY of the flu epidemic of 1918 remains unknown to this day.

• A. Pathology
• B. Transmission
• C. Etiology
• D. Mortality rate

Correct answer: C

Rationale: The term 'etiology' refers to the cause or origins of a disease. In this context, the question is asking for the underlying reason or cause of the flu epidemic of 1918. Therefore, the correct answer is C. 'Etiology.' Choice A, 'Pathology,' is incorrect as it refers to the study of diseases rather than the cause itself. Choice B, 'Transmission,' is incorrect as it relates to how a disease spreads rather than its cause. Choice D, 'Mortality rate,' is incorrect as it refers to the number of deaths caused by a disease rather than the cause of the disease itself.

4. According to the Law of Universal Gravitation, the gravitational force between two objects is directly proportional to what factor?

• A. the gravitational constant
• B. the distance between them
• C. the product of their masses
• D. the square of the distance between them

Correct answer: C

Rationale: According to the Law of Universal Gravitation, the gravitational force between two objects is directly proportional to the product of their masses. The equation is: F = G × (m₁ × m₂) / r², where F is the gravitational force, G is the gravitational constant, m₁ and m₂ are the masses of the two objects, and r is the distance between them. Choice A is incorrect because the gravitational constant is a constant value. Choice B is incorrect because the distance between the objects affects the strength of the gravitational force inversely proportional to the square of the distance, not directly proportional. Choice D is incorrect as it represents the inverse square law, where the gravitational force decreases with the square of the distance between the objects.

5. Ocean waves may tear sponges into pieces, each of which may grow into a new sponge. What is this form of reproduction called?

• A. Budding
• B. Vegetative propagation
• C. Binary fission
• D. Fragmentation

Correct answer: D

Rationale: Fragmentation is the form of asexual reproduction where an organism breaks into fragments, and each fragment can grow into a new individual. In the case of sponges being torn into pieces by ocean waves, each piece has the potential to develop into a new sponge, making fragmentation the correct answer in this scenario. Budding is a form of asexual reproduction where a new organism develops as an outgrowth from the parent organism. Vegetative propagation involves the growth of new individuals from plant parts like stems or roots. Binary fission is a method of reproduction seen in some single-celled organisms where one cell divides into two identical cells.
