1. What are polymers?

• A. Large molecules formed by repeating units called monomers
• B. Simple organic molecules with low boiling points
• C. Highly reactive compounds used in industrial processes
• D. Insoluble solids with no definite structure

Correct answer: A

Rationale: Polymers are large molecules formed by repeating units called monomers. These monomers link together to form long chains or networks, giving polymers their unique properties such as flexibility, strength, and durability. Choice B is incorrect because polymers are not simple organic molecules with low boiling points, but rather complex structures formed by polymerization. Choice C is incorrect as polymers are not necessarily highly reactive compounds, and they are not exclusively used in industrial processes. Choice D is incorrect because polymers can have varying solubilities and structures depending on their composition and properties.

2. Margery is planning a vacation, and her round-trip airfare will cost $572. Her hotel costs $89 per night, and she will be staying at the hotel for five nights. She has allotted a total of $150 for sightseeing and expects to spend about $250 on meals. She will receive a 10% discount on the hotel price after the first night. What is the total amount Margery expects to spend on her vacation?

• A. $1,328.35
• B. $1,373.50
• C. $1,381.40
• D. $1,417.60

Correct answer: C

Rationale: To calculate Margery's total expenses: Airfare ($572) + Hotel ($89 * 5 nights) = $572 + $445 = $1017. After the first night's stay, Margery receives a 10% discount on the remaining four nights, making the total hotel cost $445 - (10% of $89) = $445 - $8.90 = $436.10. Adding sightseeing ($150) and meals ($250) to the total gives $1017 + $150 + $250 = $1417. Margery's expected expenses are $1417, not $1381.40 as stated in the original rationale. Therefore, the correct answer is $1,417.60 (Option D).

3. Which word choices will correctly complete the sentence? Increasing the price of bus fares has had a greater effect on ridership than expected.

• A. affect; then
• B. affect; than
• C. effect; then
• D. effect; than

Correct answer: D

Rationale: The correct answer is D: 'effect; than.' In this sentence, 'effect' is the appropriate word to use as it signifies the result of increasing bus fares on ridership. Additionally, 'than' is the correct word for making a comparison. Choice A and B are incorrect as 'affect' is a verb, while 'effect' is the noun needed in this sentence. Choice C is incorrect as 'then' is used to indicate time or sequence, which is not suitable in this context.

4. Which term describes a position closer to the midline of the body? Example: The chest is medial to the arm.

• A. Lateral
• B. Medial
• C. Proximal
• D. Distal

Correct answer: B

Rationale: The correct answer is 'B: Medial.' 'Medial' refers to a position closer to the midline of the body, while 'lateral' refers to a position further from the midline. 'Proximal' describes a position closer to the point of attachment or trunk of the body, while 'distal' refers to a position further away from the point of attachment or trunk.

5. Which word in the following sentence is an adverb?

• A. Likely
• B. Annoyed
• C. Assigned
• D. Unnecessary

Correct answer: A

Rationale: The correct answer is 'A: Likely.' An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'likely' is an adverb that modifies the verb 'annoyed,' expressing the probability or likelihood of the action. The other choices, 'B: Annoyed,' 'C: Assigned,' and 'D: Unnecessary,' are not adverbs. 'Annoyed' is a past tense verb, 'Assigned' is a past tense verb, and 'Unnecessary' is an adjective describing the type of busy work assigned. Therefore, 'A: Likely' is the only adverb in the sentence.
