1. What is an actuary?

• A. A doctor who works in a hospital.
• B. The same as a hospitalist.
• C. An insurance agent who works in a hospital.
• D. A person who assesses insurance risks and premiums.

Correct answer: D

Rationale: An actuary is a person who assesses insurance risks and premiums. This is the primary role of an actuary, involving the analysis of financial consequences of risk. Choice A is incorrect as actuaries are not medical professionals. Choice B is incorrect as a hospitalist is a physician who works in a hospital, not related to actuarial work. Choice C is incorrect as actuaries are not insurance agents; they focus on risk assessment and not sales.

2. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?

• A. It increases as the box moves further.
• B. It decreases as the box slows down.
• C. It remains constant throughout the motion.
• D. It becomes zero once the box stops.

Correct answer: D

Rationale: Work done is defined as the product of the force applied and the distance moved in the direction of the force. In this scenario, when the box comes to a stop, the displacement becomes zero, leading to zero work done by the person. Choice A is incorrect as the work done is not increasing, but rather decreasing as the box slows down. Choice B is incorrect because the work done does not decrease as the box slows down; it becomes zero when the box stops. Choice C is incorrect as the work done is not constant but decreases to zero when the box stops.

3. If a scientist finds that the results of her experiment seem to contradict her hypothesis, what is the best course of action?

• A. Publish the results anyway, acknowledging that her hypothesis seems to have been incorrect.
• B. Keep trying the experiment until the results match her hypothesis.
• C. Publish the results, retroactively changing the hypothesis.
• D. None of the above; this cannot occur. The experimental results cannot contradict the hypothesis, by definition.

Correct answer: A

Rationale: The best course of action is to publish the results anyway, acknowledging that her hypothesis seems to have been incorrect. Science relies on accurate reporting and transparency, even if the results do not align with the original hypothesis. This allows for further discussion, analysis, and potentially new hypotheses to be developed based on the findings. It is essential in scientific research to report both positive and negative results to contribute to the body of knowledge and advance understanding in the field. Choice B is incorrect because persisting with the same experiment to force results to align with the hypothesis goes against scientific integrity and may lead to biased conclusions. Choice C is incorrect as changing the hypothesis after obtaining results is not scientifically sound and undermines the credibility of the research. Choice D is incorrect because science embraces the possibility of experimental results contradicting hypotheses, as this provides valuable insights for refining theories and expanding scientific knowledge.

4. Which of the following uses commas in a series correctly?

• A. Jericka went to the store for milk, bread, and eggs.
• B. For breakfast, Jason wanted to make French toast, bacon, and eggs.
• C. Aj had a lot to do the next day, including homework, hockey practice, and chores.
• D. Paz's mom, dad, and sister would come to watch his game.

Correct answer: A

Rationale: Option A is the correct answer as it uses commas to separate items in a series ('milk, bread, and eggs'). In option B, the comma after 'bacon' is unnecessary. Option C correctly uses commas to separate the items in the series ('homework, hockey practice, and chores'). Option D incorrectly omits commas between 'mom' and 'dad,' and 'dad' and 'sister,' making it incorrect for a series of three or more items.

5. Which of the following sentences is spelled correctly?

• A. He always adds insightful, relevant remarks to the conversation.
• B. Her comments were relevant to the class discussion.
• C. His remarks were not relevant to the current situation.
• D. Her suggestion has no relevance to issues discussed at the conference.

Correct answer: A

Rationale: Choice A is the correct answer. The word 'relevant' is spelled correctly in this sentence, and the sentence is well-constructed. In Choices B, C, and D, the word 'relevant' is misspelled as 'revelant,' 'relevent,' and 'relavance' respectively. These incorrect spellings make Choices B, C, and D grammatically incorrect, thereby making Choice A the only correct option.
