b. raising cattle
c. burning fossil fuels
d. freezing of permafrost
e. all of the above are primary causes of climate change

1. which of the following could improve air quality in newly industrialized areas?

a. enforceable policies on pollution control
b. safer technologies
c. more efficient technologies
d. a and b
e. all of the above

Explanation:

24)

• Option A: Clearing forests (deforestation) and farming can release CO₂ and reduce carbon sequestration, causing climate change.
• Option B: Raising cattle produces methane, a greenhouse gas, contributing to climate change.
• Option C: Burning fossil fuels releases large amounts of CO₂, a major climate change driver.
• Option D: Freezing of permafrost is a consequence (not a cause) of climate change; warming thaws permafrost, not freezing it.
• Option E: Incorrect as D is not a cause.

• Option A: Enforceable pollution control policies regulate emissions, improving air quality.
• Option B: Safer technologies reduce harmful emissions during industrial processes.
• Option C: More efficient technologies minimize waste and emissions, enhancing air quality.
• Option D: Combines A and B, but E includes all.
• Option E: All (enforceable policies, safer tech, more efficient tech) help improve air quality in industrial areas.

Answer:

D. freezing of permafrost
