1. What does Coulomb’s law relate to?

• A. electrostatic interaction
• B. rigid body motion
• C. heat conduction
• D. universal gravitation

Correct answer: A

Rationale: Coulomb's law is a fundamental principle in physics that deals with the electrostatic interaction between charged particles. It states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. This law is crucial in understanding and predicting the behavior of electrically charged objects. Choices B, C, and D are incorrect because Coulomb's law specifically focuses on electrostatic interactions between charges, not rigid body motion, heat conduction, or universal gravitation.

2. What statement from the article draws a conclusion?

• A. Chopsticks can be hard to use.
• B. Eating with cutlery was invented in Europe.
• C. It is interesting to discover new ways to do things.
• D. Space travel has created new challenges for eating.

Correct answer: C

Rationale: The correct answer is C: 'It is interesting to discover new ways to do things.' This statement draws a conclusion by summarizing the learning experience mentioned throughout the article. It reflects on the diversity of eating habits across cultures and the fascination in discovering and adapting to new methods of accomplishing tasks. Choice A is incorrect as it describes a fact rather than drawing a conclusion. Choice B is incorrect as it also presents a historical fact without concluding or summarizing any information. Choice D is incorrect because it states a fact about the challenges of space travel without offering a concluding remark or summarizing the topic.

3. What does oral mean?

• A. Through the skin
• B. Given through or affecting the mouth
• C. Injected
• D. Absorbed through digestion

Correct answer: B

Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth. Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth. Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion. Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.

4. A common example of a shear-thinning (non-Newtonian) fluid is:

• A. Water
• B. Ketchup
• C. Air
• D. Alcohol

Correct answer: B

Rationale: The correct answer is B: Ketchup. Shear-thinning fluids become less viscous under stress. Ketchup is an example of a shear-thinning fluid because its viscosity decreases when it is shaken or squeezed, allowing it to flow more easily. Choice A, Water, is a Newtonian fluid with a constant viscosity regardless of stress. Choice C, Air, is also a Newtonian fluid. Choice D, Alcohol, does not exhibit shear-thinning behavior; it typically has a constant viscosity as well.

5. Which part of the brain is responsible for regulating emotions and memory?

• A. Cerebrum
• B. Cerebellum
• C. Amygdala
• D. Brainstem

Correct answer: C

Rationale: The amygdala, located in the temporal lobe of the brain, is responsible for regulating emotions and memory, particularly those related to fear and pleasure. It plays a crucial role in processing emotional responses, forming emotional memories, and modulating emotional reactions. The cerebrum (Choice A) is responsible for higher brain functions such as thought and action. The cerebellum (Choice B) is mainly involved in coordination and balance. The brainstem (Choice D) controls basic life functions such as breathing and heart rate.
