If you have been consulted by rapidly growing city authorities to improve air quality, which is deteriorated in the past ten years, your first suggestion is to

Options

A. Removal of hydroelectric power station near the city
B. Move or close the cattle feed lots near the river
C. Strict usage of leaded petrol
D. Promotion of mass transport systems

Answer

To improve air quality in a rapidly growing city that has deteriorated over the past ten years, the first suggestion would be to promote a mass transport system. Here’s a step-by-step breakdown of the reasoning:

### Step 1: Assess the Current Air Quality Situation
- Understand the factors contributing to the decline in air quality over the past decade. This may include increased vehicular emissions, industrial pollution, and other urban activities.

### Step 2: Identify Major Pollutants
- Determine the primary sources of air pollution in the city. Common sources include automobiles, industrial emissions, and construction activities.

### Step 3: Evaluate Transportation Options
- Consider the role of transportation in air quality. Personal vehicles are a significant source of air pollution. Promoting public transportation can help reduce the number of individual cars on the road.

### Step 4: Suggest a Mass Transport System
- Propose the implementation or enhancement of a mass transport system (e.g., buses, subways, trams). This can significantly reduce the number of vehicles on the road, leading to lower emissions.

### Step 5: Additional Measures
- While promoting mass transport is the first suggestion, additional measures could include:
- Implementing stricter emission standards for vehicles.
- Encouraging the use of electric vehicles.
- Increasing green spaces in the city to improve air quality.

### Conclusion
- By promoting a mass transport system, the city can effectively reduce air pollution levels and improve overall air quality.
