1. What force was applied to the object that was moved if 100 N⋅m of work is done over 20 m?

Correct answer: A

Rationale: Work is calculated using the formula Work = Force x Distance. Given that 100 N⋅m of work is done over 20 m, we can rearrange the formula to solve for Force. Force = Work / Distance. Plugging in the values, we get Force = 100 N⋅m / 20 m = 5 N. Therefore, the force applied to the object that was moved is 5 N. Choice B (80 N) is incorrect because it doesn't match the calculated force of 5 N. Choice C (120 N) is incorrect as it is higher than the calculated force. Choice D (2,000 N) is incorrect as it is significantly higher than the correct force of 5 N.

2. A truculent patient is ______

Correct answer: B

Rationale: A truculent patient is characterized by being argumentative or hostile. This type of patient tends to be confrontational and uncooperative, often displaying aggressive behavior. Choice A, 'Friendly,' is incorrect as truculent patients are not known for their friendliness. Choice C, 'Cooperative,' is also incorrect as truculent patients are the opposite of cooperative. Choice D, 'Passive,' is incorrect because truculent patients are not passive but rather assertive and combative.

3. Gus is making a chili recipe that calls for three parts beans to five parts ground beef. If he is using 8 cups of ground beef for a big family dinner, how many cups of beans will Gus need?

Correct answer: B

Rationale: For every 3 parts of beans, Gus needs 5 parts of ground beef. This means the ratio of beans to beef is 3:5. If Gus is using 8 cups of ground beef, the total parts would be 3 parts beans to 5 parts beef, which is a total of 8 parts. To find out how many cups of beans Gus needs, we can set up a proportion: 3/5 = x/8. Cross multiplying gives us 5x = 24. Solving for x, we get x = 4. Therefore, Gus will need 4 cups of beans. Choice A, C, and D are incorrect as they do not align with the correct proportion calculation.

4. Another word for CONTEMPLATING is?

Correct answer: C

Rationale: "Pondering" is another word for contemplating because it means to think about something carefully or thoroughly. Both terms imply deep reflection or consideration of a subject or idea. Therefore, "pondering" best captures the meaning of contemplating among the given choices.

5. When a person finds ________________ in a stressful situation, it helps to breathe deeply.

Correct answer: A

Rationale: In this sentence, 'Oneself' is the correct reflexive pronoun to use when referring back to the singular subject 'a person.' It is important to match the reflexive pronoun with the singular noun. 'Yourself' and 'Themselves' are plural forms and do not agree with the singular subject 'a person.' 'Itself' is used for inanimate objects, not for people. Therefore, 'Oneself' is the most suitable choice in this context.
