Question:

$\text{Pollution can be controlled by-}$ $1. \text{Sewage treatment.}$ $2. \text{Checking atomic blasts.}$ $3. \text{Manufacturing electrically operated vehicles.}$ $4. \text{All of the above.}$

Options:

1. $\text{Sewage treatment.}$
2. $\text{Checking atomic blasts.}$
3. $\text{Manufacturing electrically operated vehicles.}$
4. $\text{All of the above.}$

Solution:

$\text{Recycle the waste can control the pollution.}$ $\text{Pollution prevention protects the environment by conserving and protecting natural resources while strengthening economic growth through more efficient production in industry and less need for households, businesses and communities to handle waste.}$ $\text{Specific means of pollution control might include refuse disposal systems such as sanitary landfills, emission control system for automobiles, sedimentation tanks in sewerage systems,}$ $\text{the electrostatic precipitation of impurities from industrial gas, or the practice of recycling.}$
