Question

All of these will directly or indirectly reduce the contribution to greenhouse gases except

• A. Encouraging the use of public transportation
• B. Walking
• C. Biking or Using motorcycles
• D. Increasing the cost of car ownership and fuel costs
• E. Creating car-free zones

Answer 1

The correct option is C Biking or Using motorcycles

A. Encouraging the use of public transport will reduce air pollution as this will lead to less use of cars and other personal transport vehicles. If many people instead of travelling by their personal transport vehicle, will use the public transport, then there will be less emission of green house gases.

B. Walking instead of using a vehicle for travelling can also reduce green house gases emission as no transport vehicle will be used and no harmful gases will be released.

C. Biking will contribute to air pollution as green house gases like carbon dioxide are released as the fuel is burnt in the engine of the bike.

D. Increasing the cost of car ownership and fuel costs will tend to decrease in use of less cars as people won't spend much money for this. So, this will also decrease the air pollution and the emission of green house gases.

E. Creating car free zones will make the people to avoid the use of cars and thus, this will also prevent the emission of green house gases.

Hence, all the options except biking, will directly or indirectly reduce the contribution to green house gases.

So, the correct answer is 'Biking'.
