1. Tom needs to buy ink cartridges and printer paper. Each ink cartridge costs $30. Each ream of paper costs $5. He has $100 to spend. Which of the following inequalities may be used to find the combinations of ink cartridges and printer paper he may purchase?

• A. 30c + 5p ≤ 100
• B. 30c + 5p = 100
• C. 30c + 5p > 100
• D. 30c + 5p < 100

Correct answer: A

Rationale: The correct inequality is 30c + 5p ≤ 100. This represents the combinations of ink cartridges (c) and printer paper (p) that Tom may purchase, ensuring the total cost is less than or equal to $100. Choice B is incorrect because the total cost should be less than or equal to $100, not equal to. Choices C and D are also incorrect as they indicate the total cost being greater than $100, which is not the case given Tom's budget limit.

2. Which of the following is a logical conclusion that can be derived from the announcement above?

• A. The library is planning to purchase more computers to accommodate longer usage.
• B. The library is facing budget cuts and implementing the fee to compensate for them.
• C. The library has added the fee to discourage patrons from spending too long on the computers.
• D. The library is covering its Internet service costs by passing on the fee to patrons.

Correct answer: C

Rationale: The logical conclusion that can be derived from the announcement is that the library has added the fee to discourage patrons from spending too long on the computers. This conclusion is supported by the fact that the library is limiting computer usage to 30 minutes and implementing a fee for extended use. Choice A is incorrect because there is no indication in the announcement that the library plans to purchase more computers. Choice B is incorrect as there is no mention of budget cuts or using the fee to compensate for them in the announcement. Choice D is incorrect as there is no information in the announcement about the library covering its Internet service costs by passing on the fee to patrons.

3. Which unit of measurement is larger, inches or centimeters?

• A. Inches are larger
• B. Centimeters are larger
• C. They are the same size
• D. It depends on the measurement

Correct answer: A

Rationale: Inches are larger than centimeters. This is because one inch is equivalent to 2.54 centimeters. Therefore, when comparing the two units, inches are greater in length than centimeters. Choice B is incorrect as centimeters are smaller than inches. Choice C is incorrect as inches and centimeters are not the same size. Choice D is incorrect as the relationship between inches and centimeters is fixed, with inches being larger in general.

4. The American Academy of Arts and Sciences includes members whose topics of study span many disciplines such as math, science, arts, humanities, public affairs, and business. Which of the following is an appropriate synonym for disciplines as it is used in the sentence?

• A. locations
• B. regions
• C. punishments
• D. fields

Correct answer: D

Rationale: In this context, 'disciplines' refers to specific areas of study or fields of expertise. Therefore, the most appropriate synonym for 'disciplines' would be 'fields.' Options A, B, and C do not accurately convey the meaning of 'disciplines' in the given sentence. 'Locations' and 'regions' refer to physical places, while 'punishments' is entirely unrelated to the context of academic or professional fields of study.

5. A scientist is trying to determine how much poison will kill a rat the fastest. Which of the following statements is an example of an appropriate hypothesis?

• A. Rats that are given lots of poison seem to die quickly.
• B. Does the amount of poison affect how quickly the rat dies?
• C. The more poison a rat is given, the quicker it will die.
• D. Poison is fatal to rats.

Correct answer: C

Rationale: A valid hypothesis must be a testable statement that predicts a relationship between variables. Option C is the only statement that presents a clear cause-and-effect relationship between the amount of poison given and the time it takes for the rat to die. Option A is descriptive without predicting an outcome, option B is a question rather than a statement, and option D is a general fact about poison and rats, lacking a specific hypothesis for testing.
