1. What punctuation is needed in the following sentence to make it correct? The days seem long, but the nights seem even longer.

• A. Period
• B. Comma
• C. Colon
• D. Apostrophe

Correct answer: B

Rationale: The sentence needs a comma before the conjunction 'but' to correctly join the two independent clauses 'The days seem long' and 'the nights seem even longer.' This comma helps to create a clear separation between the contrasting ideas in the sentence. Choice A (Period) is incorrect because a period would create two separate sentences rather than connecting them. Choice C (Colon) is incorrect as colons are used to introduce lists, explanations, or quotations. Choice D (Apostrophe) is incorrect as it is not needed in this sentence.

2. What is the definition of Bilateral?

• A. Occurring on one side
• B. Present on two sides
• C. Occurring in random areas
• D. Not occurring

Correct answer: B

Rationale: The correct definition of bilateral is something that is present on two sides. This term is commonly used in medical contexts to describe conditions or procedures that affect or involve both sides of a particular part of the body. Choice A, 'Occurring on one side,' is incorrect because bilateral refers to both sides, not just one. Choice C, 'Occurring in random areas,' is incorrect as bilateral specifically means on two sides, not random areas. Choice D, 'Not occurring,' is also incorrect as bilateral refers to something present on two sides, not the absence of occurrence.

3. Round to the nearest whole number: 4748 ÷ 12 =

• A. 372
• B. 384
• C. 396
• D. 412

Correct answer: C

Rationale: To find the answer, divide 4748 by 12: 4748 ÷ 12 = 395.666... Since we are rounding to the nearest whole number, we round up to 396 because the decimal part (.666) is greater than .5. Choice A (372) is too low as it does not account for the decimal value. Choice B (384) is also too low. Choice D (412) is too high as it goes beyond the correct rounded value.

4. During an isothermal (constant temperature) expansion, what is the work done by the gas on the surroundings?

• A. Positive and equal to the change in internal energy.
• B. Zero.
• C. Negative and equal to the change in internal energy.
• D. Positive and greater than the change in internal energy.

Correct answer: D

Rationale: In an isothermal expansion, the temperature remains constant, meaning there is no change in internal energy. However, the gas still does work on the surroundings as it expands, and this work is positive. Since internal energy does not change, the correct answer is D, 'Positive and greater than the change in internal energy.' Choice A is incorrect because the work done is not equal to the change in internal energy. Choice B is incorrect as work is done during the expansion. Choice C is incorrect since the work done is not negative during an isothermal expansion.

5. In which state of matter are particles packed tightly together in a fixed position?

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

Correct answer: B

Rationale: In a 'solid' state, particles are tightly packed in fixed positions, maintaining a definite shape and volume. This arrangement allows solids to maintain a rigid structure. Liquids have particles that are close together but can move past each other, giving them the ability to flow and take the shape of their container. Gases have particles that are far apart and move freely, leading to their ability to expand to fill any container. Plasma is an ionized gas where particles have high energy levels and are not packed tightly together, making it an uncommon state of matter on Earth.
