1. What is matter that has a definite shape and volume?

• A. Liquid
• B. Solid
• C. Gas
• D. Plasma

Correct answer: B

Rationale: Matter that has a definite shape and volume is referred to as a solid. Solids maintain their shape and volume under normal conditions, unlike liquids that have a definite volume but take the shape of their container, gases that have neither a definite shape nor volume, and plasma which is a state of matter with no definite shape or volume and consists of charged particles.

2. Convert the following military time to regular time: 15:17:52.

• A. 2:17 PM
• B. 3:17 PM
• C. 5:17 AM
• D. 9:17 AM

Correct answer: B

Rationale: To convert military time to regular time, subtract 12 from the hours if it is 13 or greater. In this case, 15:17:52 becomes 3:17:52 PM. Choice A (2:17 PM) is incorrect as it doesn't adjust for the 12-hour conversion. Choice C (5:17 AM) and Choice D (9:17 AM) are incorrect as they don't reflect the correct conversion from military time to regular time.

3. What is the function of the pancreas in digestion?

• A. Secreting digestive enzymes
• B. Producing bile
• C. Storing glucose
• D. Regulating blood sugar levels

Correct answer: A

Rationale: The correct answer is A: Secreting digestive enzymes. The pancreas aids in digestion by secreting digestive enzymes that are essential for breaking down carbohydrates, fats, and proteins in the small intestine. These enzymes help in the absorption of nutrients from food, facilitating the digestive process. Choices B, C, and D are incorrect. The pancreas does not produce bile (choice B), store glucose (choice C), or primarily regulate blood sugar levels (choice D) in the context of digestion.

4. What is the meaning of the word composed in the first paragraph?

• A. To consist of
• B. To break apart
• C. To mix with other elements
• D. To heat up

Correct answer: A

Rationale: The word 'composed' means to be made up of or to consist of something. In the provided extract, it describes how a single drop of water is composed of an oxygen atom and two hydrogen atoms. Therefore, the correct answer is 'To consist of.' Choice B, 'To break apart,' is incorrect as it is the opposite of 'composed.' Choice C, 'To mix with other elements,' is incorrect as 'composed' refers to being made up of specific components, not mixed with others. Choice D, 'To heat up,' is unrelated to the meaning of 'composed' in this context.

5. Two objects attract each other with a gravitational force of 12 units. If you double the mass of both objects, what is the new force of attraction between them?

• A. 3 units
• B. 6 units
• C. 24 units
• D. 48 units

Correct answer: C

Rationale: The gravitational force between two objects is directly proportional to the product of their masses. When you double the masses of both objects, the force of attraction between them increases by a factor of 2 x 2 = 4. Therefore, the new force of attraction between the two objects will be 12 units x 4 = 24 units. Choices A, B, and D are incorrect because doubling the mass results in a quadruple increase in force, not a linear one.
