Question 1

The Clean Air Act in the United States regulates six 'criteria air pollutants.' Which of the following is NOT one of them?

Accepted Answer

Carbon dioxide (CO₂)

Answer

CO₂ is not a criteria air pollutant under the Clean Air Act; the six criteria pollutants are O₃, PM, CO, NO₂, SO₂, and Pb.

Question 2

In environmental impact assessment, a 'negative feedback loop' in a system:

Accepted Answer

Counteracts disturbances and stabilizes the system

Answer

Negative feedback opposes change, returning a system toward its equilibrium state, providing self-regulation and stability.

Question 3

The primary purpose of a secondary wastewater treatment process is to:

Accepted Answer

Biologically remove dissolved organic matter using microorganisms

Answer

Secondary treatment (activated sludge, trickling filters) uses biological processes to degrade dissolved and suspended organic matter after primary settling.

Question 4

Systems thinking in engineering design emphasizes:

Accepted Answer

Understanding interactions and emergent behavior of components within the whole system

Answer

Systems thinking recognizes that system behavior emerges from interactions between components and cannot be understood by analyzing parts in isolation.

Question 5

A P-diagram (Parameter Diagram) in robust engineering design identifies:

Accepted Answer

Signal, noise, control, and response parameters of a system

Answer

A P-diagram maps the system transformation from signal (input) to response (output), identifying control factors, noise factors, and ideal function.
