1. What can be inferred about the data collected by smart cities?

• A. It is easily accessible and transparent to the public.
• B. It is solely used for optimizing infrastructure and services.
• C. It may raise privacy concerns for individual citizens.
• D. It is always accurate and free from technical errors.

Correct answer: C

Rationale: The passage specifically mentions concerns about data privacy, implying potential issues for individuals.

2. Which property of a substance remains constant regardless of changes in its shape or size?

• A. Mass
• B. Weight
• C. Volume
• D. Density

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in its shape or size.

3. Electroencephalography (EEG) measures electrical activity in the brain, primarily reflecting the activity of:

• A. Neurons
• B. Astrocytes
• C. Oligodendrocytes
• D. Microglia

Correct answer: A

Rationale: The correct answer is A: Neurons. Electroencephalography (EEG) measures the electrical activity in the brain, which is primarily generated by the neurons. Neurons are the main cells responsible for transmitting electrical signals in the brain, making them the key source of the brain's electrical activity. Astrocytes, oligodendrocytes, and microglia are important supporting cells in the brain but do not generate the electrical impulses that EEG measures. Therefore, the correct choice is A: Neurons.

4. She plans of assigning competent people to fill the roles designed in the hierarchy. Which

• A. Staffing
• B. Scheduling
• C. Recruitment
• D. Induction

Correct answer: B

Rationale: The correct answer is B: Scheduling. Scheduling involves assigning people to specific tasks or roles within an organization based on the hierarchy and operational needs. In this scenario, the focus is on assigning competent individuals to fill the roles outlined in the hierarchy, which aligns with the concept of scheduling. Staffing refers to the overall process of acquiring, deploying, and retaining a workforce; recruitment specifically pertains to attracting and selecting candidates for job roles; and induction involves the orientation and integration of new employees into the organization. Therefore, the most relevant term in this context is scheduling.

5. What is the SI unit of measurement for momentum?

• A. Newton (N)
• B. Kilogram-meter per second (kg·m/s)
• C. Joule (J)
• D. Newton-second (N·s)

Correct answer: b

Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).

6. Define power in physics.

• A. The rate of change of energy
• B. The rate of doing work or transferring energy
• C. The measure of an object's potential energy
• D. The force exerted on an object

Correct answer: b

Rationale: Power is the rate at which work is done or energy is transferred or converted.
