1. What happens to the kinetic energy of an object when its velocity is doubled?

• A. Kinetic energy remains the same
• B. Kinetic energy is halved
• C. Kinetic energy doubles
• D. Kinetic energy quadruples

Correct answer: C

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object according to the kinetic energy formula (KE = 0.5 * m * v^2). When the velocity is doubled, the kinetic energy increases by a factor of four (2^2), which means it doubles. Therefore, when the velocity of an object is doubled, its kinetic energy also doubles. Choice A is incorrect because kinetic energy is not constant but dependent on velocity. Choice B is incorrect because halving the velocity would result in 1/4 of the original kinetic energy. Choice D is incorrect as quadrupling the kinetic energy would occur if the velocity is squared, not the kinetic energy.

2. What is the function of the pituitary gland?

• A. Produces hormones that regulate growth and metabolism
• B. Filters blood and removes waste products
• C. Stores and releases bile
• D. Produces red blood cells

Correct answer: A

Rationale: The correct answer is A: Produces hormones that regulate growth and metabolism. The pituitary gland is often referred to as the 'master gland' because it produces and releases hormones that regulate various bodily functions, including growth, metabolism, reproduction, and stress response. It does not filter blood or remove waste products (option B), store and release bile (option C), or produce red blood cells (option D). The pituitary gland's primary role is in hormone production and regulation, influencing many essential functions in the body.

3. Given this new information, which cinema is the best option for Thomas and his sister?

• A. Twin Theatres
• B. Reveler Cinema
• C. Big Screen 14
• D. Best Seat in The House

Correct answer: D

Rationale: The best cinema option for Thomas and his sister after the unexpected rearrangement of their schedules is Best Seat in The House. This is because the only showing available after 10:30 p.m. is at 11:25 p.m. at Best Seat in The House. None of the other cinemas have showings available after 10:30 p.m., making Best Seat in The House the optimal choice for them to catch the film. Twin Theatres, Reveler Cinema, and Big Screen 14 do not have showings after 10:30 p.m., so they are not suitable options for Thomas and his sister given their schedule constraints.

4. Which element is used in insulin and promotes glucose uptake into cells for energy production?

• A. Zinc
• B. Chromium
• C. Manganese
• D. Iron

Correct answer: B

Rationale: Chromium is the correct answer. Chromium is the element used in insulin that aids in its function by enhancing glucose uptake into cells and regulating blood sugar levels. It plays a crucial role in the body's energy production processes by facilitating the action of insulin. Zinc (Choice A), although important for various physiological functions, is not the element used in insulin. Manganese (Choice C) is necessary for enzyme activation but is not directly involved in insulin's function. Iron (Choice D) is essential for oxygen transport but is not the element used in insulin for promoting glucose uptake into cells.

5. What can the reader infer from this passage?

• A. The children tortured Gulliver.
• B. Gulliver traveled because he wanted to meet new people.
• C. Gulliver is considerably larger than the children who are playing around him.
• D. Gulliver has a genuine love and enthusiasm for people of all sizes.

Correct answer: C

Rationale: The correct answer is C. In the passage, it is mentioned that the children play in Gulliver's hair, implying that he is considerably larger than them. This suggests that Gulliver is of a significant size compared to the children. Choice A is incorrect as there is no indication of the children torturing Gulliver in the passage. Choice B is incorrect because the passage does not mention Gulliver's reason for traveling. Choice D is incorrect as the passage does not provide evidence of Gulliver's love and enthusiasm for people of all sizes.
