Example Questions and Solutions

Let's walk through a few example questions to illustrate how to apply these strategies:

Question 1:

Which of the following is a primary pollutant produced by burning coal?

(A) Ozone (O3) (B) Sulfur Dioxide (SO2) (C) Nitric Acid (HNO3) (D) Peroxyacyl Nitrates (PANs) (E) Carbon Dioxide (CO2)

Solution:

• Understanding the Question: The question asks about a primary pollutant, meaning a pollutant emitted directly from a source.
• Elimination: Ozone, Nitric Acid, and PANs are secondary pollutants formed in the atmosphere. Carbon Dioxide is a product of combustion but often listed alongside sulfur dioxide.
• Correct Answer: (B) Sulfur Dioxide (SO2) is a primary pollutant released when coal containing sulfur is burned.

Question 2:

Eutrophication in lakes and ponds is often caused by:

(A) Acid deposition from industrial emissions. (B) Runoff containing fertilizers and sewage. (C) Thermal pollution from power plants. (D) The introduction of invasive species. (E) Increased levels of heavy metals in the water.

Solution:

• Understanding the Question: Eutrophication refers to excessive nutrient enrichment in water bodies.
• Elimination: Acid deposition, thermal pollution, invasive species, and heavy metals can all harm aquatic ecosystems, but they are not the primary cause of eutrophication.
• Correct Answer: (B) Runoff containing fertilizers and sewage introduces excess nutrients (nitrogen and phosphorus) into the water, leading to eutrophication.

Question 3:

A city implements a "cap-and-trade" program to reduce sulfur dioxide emissions. Which of the following best describes how this program works?

(A) The city sets a limit on the total amount of sulfur dioxide that can be emitted and issues permits to companies, which can be bought and sold. (B) The city requires all companies to install scrubbers on their smokestacks to remove sulfur dioxide. (C) The city imposes a tax on companies based on the amount of sulfur dioxide they emit. (D) The city provides subsidies to companies that reduce their sulfur dioxide emissions. (E) The city bans the use of coal with high sulfur content.

Solution:

• Understanding the Question: The question asks about the mechanism of a cap-and-trade program.
• Elimination: The other options describe different pollution control strategies (e.g., technology mandates, taxes, subsidies, bans).
• Correct Answer: (A) In a cap-and-trade program, a limit (cap) is set on total emissions, and companies are issued permits that they can trade (buy and sell) with each other.
