1. What is the purpose of this passage?

Correct answer: A

Rationale: The correct answer is A. The passage describes the reproductive habits of the sun-fish, focusing on how the mother sun-fish provides and guards her spawn until they are ready to take care of themselves. Choice B is incorrect as the passage does not delve into the broader ecosystem of the sun-fish. Choice C is incorrect as there is no persuasive element in the passage about protecting aquatic ecosystems. Choice D is incorrect as the passage does not discuss the mating habits of sun-fish but rather the care provided by the mother sun-fish.

2. Simplify (x^2 - y^2) / (x - y)

Correct answer: A

Rationale: The expression 𝑥^2 - 𝑦^2 is a difference of squares, which follows the identity: 𝑥^2 - 𝑦^2 = (𝑥 + 𝑦)(𝑥 - 𝑦). Therefore, the given expression becomes: (𝑥^2 - 𝑦^2) / (𝑥 - 𝑦) = (𝑥 + 𝑦)(𝑥 - 𝑦) / (𝑥 - 𝑦). Since (𝑥 - 𝑦) appears in both the numerator and the denominator, they cancel each other out, leaving 𝑥 + 𝑦. Thus, the simplified form of (𝑥^2 - 𝑦^2) / (𝑥 - 𝑦) is 𝑥 + 𝑦. Therefore, the correct answer is A (x + y). Option B (x - y) is incorrect as it does not result from simplifying the given expression. Option C (1) is incorrect as it does not account for the variables x and y present in the expression. Option D ((x + y)/(x - y)) is incorrect as it presents the simplified form in a different format than the correct answer.

3. Which deadly disease was eliminated through an intensive vaccination program?

Correct answer: B

Rationale: Smallpox was eradicated globally through an intensive vaccination program. The World Health Organization (WHO) led a successful global campaign to vaccinate people against smallpox, ultimately leading to its eradication in 1980. AIDS, diabetes type 1, and rheumatoid arthritis are serious conditions, but they were not eliminated through vaccination programs like smallpox. Therefore, the correct answer is B, Smallpox. AIDS is caused by the human immunodeficiency virus (HIV) and remains a significant global health issue. Diabetes type 1 is an autoimmune condition where the body attacks insulin-producing cells, leading to high blood sugar levels. Rheumatoid arthritis is an autoimmune condition that primarily affects the joints, causing inflammation and pain.

4. Which gland produces the hormone responsible for regulating blood sugar levels?

Correct answer: C

Rationale: The correct answer is the pancreas. The hormone responsible for regulating blood sugar levels is insulin, which is produced by the pancreas. The pituitary gland produces various hormones that regulate other endocrine glands, the thyroid gland produces hormones that regulate metabolism, and the adrenal glands produce hormones involved in the stress response. Therefore, choices A, B, and D are incorrect in the context of regulating blood sugar levels.

5. What is the definition of 'acceleration' in terms of motion?

Correct answer: A

Rationale: Acceleration is defined as the rate of change of velocity of an object over time. It represents how an object's velocity is changing, either by speeding up, slowing down, or changing direction. Option B, 'Speed in a straight line,' actually refers to velocity, not acceleration. Option C, 'Distance covered in a given time,' is more related to speed, as it measures how much ground is covered in a specific time period. Option D, 'Force applied to an object,' is not the definition of acceleration; it is a force exerted on an object that can cause acceleration.
