Which of the following is a primary source of air pollution in urban areas?

  1. Public transportation

  2. Private vehicles

  3. Industrial activities

  4. Residential heating


Correct Option: B
Explanation:

Private vehicles, particularly those powered by fossil fuels, are a major source of air pollution in urban areas, emitting harmful pollutants such as carbon monoxide, nitrogen oxides, and particulate matter.

How does public transportation contribute to improved air quality?

  1. It reduces the number of vehicles on the road.

  2. It promotes walking and cycling.

  3. It encourages the use of cleaner energy sources.

  4. All of the above


Correct Option: D
Explanation:

Public transportation contributes to improved air quality by reducing the number of vehicles on the road, promoting walking and cycling, and encouraging the use of cleaner energy sources such as electric and hybrid vehicles.

Which of the following is a benefit of using public transportation for air quality?

  1. Reduced traffic congestion

  2. Lower greenhouse gas emissions

  3. Improved public health

  4. All of the above


Correct Option: D
Explanation:

Using public transportation offers multiple benefits for air quality, including reduced traffic congestion, lower greenhouse gas emissions, and improved public health due to reduced exposure to air pollution.

What is the primary air pollutant emitted by diesel-powered buses?

  1. Carbon monoxide

  2. Nitrogen oxides

  3. Particulate matter

  4. Sulfur dioxide


Correct Option: C
Explanation:

Diesel-powered buses emit significant amounts of particulate matter, which consists of fine particles that can penetrate deep into the lungs and cause respiratory problems.

Which of the following is a strategy to reduce air pollution from public transportation?

  1. Using cleaner energy sources

  2. Improving vehicle maintenance

  3. Promoting the use of public transportation

  4. All of the above


Correct Option: D
Explanation:

Reducing air pollution from public transportation involves a combination of strategies, including using cleaner energy sources such as electric and hybrid vehicles, improving vehicle maintenance to minimize emissions, and promoting the use of public transportation to reduce the number of vehicles on the road.

How does public transportation contribute to reducing greenhouse gas emissions?

  1. It reduces the number of vehicles on the road.

  2. It promotes walking and cycling.

  3. It encourages the use of cleaner energy sources.

  4. All of the above


Correct Option: D
Explanation:

Public transportation contributes to reducing greenhouse gas emissions by reducing the number of vehicles on the road, promoting walking and cycling, and encouraging the use of cleaner energy sources such as electric and hybrid vehicles.

Which of the following is a benefit of using public transportation for greenhouse gas emissions?

  1. Reduced traffic congestion

  2. Lower air pollution levels

  3. Improved public health

  4. All of the above


Correct Option: D
Explanation:

Using public transportation offers multiple benefits for greenhouse gas emissions, including reduced traffic congestion, lower air pollution levels, and improved public health due to reduced exposure to air pollution.

What is the primary greenhouse gas emitted by public transportation vehicles?

  1. Carbon dioxide

  2. Methane

  3. Nitrous oxide

  4. Hydrofluorocarbons


Correct Option: A
Explanation:

Public transportation vehicles, particularly those powered by fossil fuels, emit carbon dioxide as a primary greenhouse gas, contributing to climate change.

Which of the following is a strategy to reduce greenhouse gas emissions from public transportation?

  1. Using cleaner energy sources

  2. Improving vehicle maintenance

  3. Promoting the use of public transportation

  4. All of the above


Correct Option: D
Explanation:

Reducing greenhouse gas emissions from public transportation involves a combination of strategies, including using cleaner energy sources such as electric and hybrid vehicles, improving vehicle maintenance to minimize emissions, and promoting the use of public transportation to reduce the number of vehicles on the road.

How does public transportation contribute to improved public health?

  1. It reduces air pollution exposure.

  2. It promotes physical activity.

  3. It reduces stress and anxiety.

  4. All of the above


Correct Option: D
Explanation:

Public transportation contributes to improved public health by reducing air pollution exposure, promoting physical activity through walking and cycling, and reducing stress and anxiety associated with driving.

Which of the following is a benefit of using public transportation for public health?

  1. Reduced risk of respiratory problems

  2. Lower risk of cardiovascular disease

  3. Improved mental well-being

  4. All of the above


Correct Option: D
Explanation:

Using public transportation offers multiple benefits for public health, including reduced risk of respiratory problems due to lower air pollution exposure, lower risk of cardiovascular disease due to increased physical activity, and improved mental well-being due to reduced stress and anxiety.

What is the primary health concern associated with air pollution from public transportation?

  1. Respiratory problems

  2. Cardiovascular disease

  3. Cancer

  4. Neurological disorders


Correct Option: A
Explanation:

Air pollution from public transportation, particularly diesel-powered buses, is associated with an increased risk of respiratory problems such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD).

Which of the following is a strategy to reduce health risks associated with air pollution from public transportation?

  1. Using cleaner energy sources

  2. Improving vehicle maintenance

  3. Promoting the use of public transportation

  4. All of the above


Correct Option: D
Explanation:

Reducing health risks associated with air pollution from public transportation involves a combination of strategies, including using cleaner energy sources such as electric and hybrid vehicles, improving vehicle maintenance to minimize emissions, and promoting the use of public transportation to reduce the number of vehicles on the road.

How does public transportation contribute to reducing traffic congestion?

  1. It reduces the number of vehicles on the road.

  2. It promotes walking and cycling.

  3. It improves the flow of traffic.

  4. All of the above


Correct Option: D
Explanation:

Public transportation contributes to reducing traffic congestion by reducing the number of vehicles on the road, promoting walking and cycling, and improving the flow of traffic by reducing the number of single-occupancy vehicles.

Which of the following is a benefit of using public transportation for traffic congestion?

  1. Reduced travel time

  2. Lower fuel costs

  3. Less stress and frustration

  4. All of the above


Correct Option: D
Explanation:

Using public transportation offers multiple benefits for traffic congestion, including reduced travel time due to dedicated bus lanes and priority signaling, lower fuel costs due to shared transportation, and less stress and frustration due to avoiding traffic jams.
