1. Which type of reasoning has the FBI agent used?

• A. Deductive Reasoning
• B. Conductive Reasoning
• C. Quantitative Reasoning
• D. Inductive Reasoning

Correct answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing general conclusions from specific observations or instances. In this case, the FBI agent is creating a theory based on observations of specific cases rather than applying a general rule to a specific situation (which would be deductive reasoning). Conductive reasoning is not a recognized type of reasoning, and quantitative reasoning involves interpreting and analyzing quantitative information.

2. When making a dilution, what do you do?

• A. Add more solvent to a concentrated solution
• B. Change the temperature of the solution
• C. Decrease the concentration of a solution
• D. All of the above

Correct answer: C

Rationale: When making a dilution, you decrease the concentration of a solution by adding more solvent to a concentrated solution. This process does not involve changing the temperature of the solution, so option B is incorrect. Option A is also incorrect because you are not adding more solute to the solution during dilution. Therefore, the correct answer is C) Decrease the concentration of a solution. Options A and B are incorrect as dilution involves adding more solvent, not solute, and does not require changing the temperature of the solution.

3. A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?

• A. Gravitational force
• B. Normal force from the floor
• C. Air resistance
• D. None of the above

Correct answer: C

Rationale: The force that caused the ball to stop rolling across the floor is air resistance. As the ball moves through the air, air resistance acts in the opposite direction of its motion, gradually slowing it down until it comes to a stop. In this scenario, the ball is not in contact with the floor, so the normal force from the floor does not play a role in stopping the ball. Gravitational force acts to pull objects towards the center of the Earth and would not directly stop the ball in this situation. Therefore, air resistance is the force that opposes the motion of the rolling ball and causes it to come to a stop.

4. Which of the following sentences contains a colloquialism?

• A. The Centers for Disease Control and Prevention is pretty sure that the Zika virus is spread through mosquito bites.
• B. Travelers who are pregnant or considering pregnancy should consult a doctor.
• C. Some theories on the Zika virus are difficult to understand.
• D. In response, the U.S. has taken steps to prevent the spread of the Zika virus.

Correct answer: A

Rationale: The correct answer is A because the phrase 'pretty sure' is a colloquialism, making the sentence less formal. Choice B is incorrect as it is a formal recommendation. Choice C is incorrect as it contains no colloquial expressions. Choice D is incorrect as it is a straightforward statement without colloquial language.

5. 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.
