1. Which of the following words functions as an adverb in the sentence?

• A. call
• B. earlier
• C. could
• D. phone

Correct answer: B

Rationale: In the sentence, 'earlier' describes when the Hapsburg rule of the Austro-Hungarian Empire effectively ended. Adverbs modify verbs, adjectives, or other adverbs in a sentence. In this case, 'earlier' modifies the verb 'ended,' indicating the time of the action. Choice A 'call' is a verb. Choice C 'could' is a modal verb expressing possibility or ability. Choice D 'phone' is a noun, not an adverb. Therefore, 'earlier' is the only word among the options functioning as an adverb in the sentence.

2. Which of the following sentences contains an indirect object?

• A. Melissa walked to the grocery store for milk.
• B. Dante skimmed the magazine while waiting in the lobby.
• C. Jorge assigned the class some math problems.
• D. Sara went to the movie with Amal.

Correct answer: C

Rationale: In sentence C, 'Jorge assigned the class some math problems,' 'the class' is the indirect object receiving the direct object 'some math problems.' In this sentence, 'the class' is the recipient of the action, making it the indirect object. The other choices do not contain an indirect object. In sentences A, B, and D, there are no instances of an indirect object. Therefore, the correct answer is C.

3. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Constructive interference

Correct answer: D

Rationale: Constructive interference occurs when two identical waves are perfectly aligned and reinforce each other. This results in an increase in the overall amplitude of the wave. Refraction refers to the bending of waves as they pass from one medium to another, reflection is the bouncing back of waves when they encounter a boundary, and diffraction is the bending of waves around obstacles and openings. In this scenario, the waves are not changing direction or bending but rather combining to produce a wave with a larger amplitude, which is characteristic of constructive interference.

4. Which of the following is a characteristic of unsaturated fatty acids?

• A. They are solid at room temperature.
• B. They contain only single bonds.
• C. They have a higher melting point.
• D. They contain double or triple bonds.

Correct answer: D

Rationale: The correct answer is D. Unsaturated fatty acids are characterized by the presence of double or triple bonds in their carbon chain. These bonds introduce kinks in the chain, preventing tight packing, and resulting in a lower melting point compared to saturated fatty acids. Choice A is incorrect because unsaturated fatty acids are typically liquid at room temperature due to their kinked structure. Choice B is incorrect because unsaturated fatty acids contain double or triple bonds, not only single bonds. Choice C is incorrect as unsaturated fatty acids have a lower melting point compared to saturated fatty acids.

5. What is the result of (4.71 × 10^3) - (2.98 × 10^2)? Which of the following is the correct simplified expression?

• A. 1.73 × 10
• B. 4.412 × 10^2
• C. 1.73 × 10^3
• D. 4.412 × 10^3

Correct answer: D

Rationale: The correct answer is D: 4.412 × 10^3. To simplify the expression, rewrite 4.71 × 10^3 as 47.1 × 10^2. Subtract the values in front of 10^2: 47.1 - 2.98 = 44.12. Rewriting this gives 44.12 × 10^2 = 4.412 × 10^3. Choice A is incorrect as it does not account for the correct subtraction result. Choice B is incorrect as it does not correctly simplify the expression. Choice C is incorrect as it provides an incorrect power of 10 in the simplified expression.
