Burning fossil fuels - oil, coal, and natural gas - causes pollution. The environment manager of a chemical plant proposes replacement of all diesel-oil driven vehicles that run inside the plant with either rechargeable electric battery powered vehicles or solar powered vehicles. The management decided to buy battery powered vehicles because of their lower investment cost despite the requirement of installation of electric battery charging points at various locations in the plant.
Which of the following statements most seriously undermines the decision of the management?


A. Solar powered vehicles do not cause more pollution than battery powered vehicles.
B. The chemical processes in the plant causes much higher pollution than that the diesel-oil driven vehicles produce.
C. The vehicles that go inside the chemical plant need to be fitted with costly spark-proof safety devices.
D. A coal-fired power plant supplies electricity to the chemical plant.
E. Other plants in the vicinity of the chemical plant will continue to use diesel-oil driven vehicles.

Official Solution:

Burning fossil fuels - oil, coal, and natural gas - causes pollution. The environment manager of a chemical plant proposes replacement of all diesel-oil driven vehicles that run inside the plant with either rechargeable electric battery powered vehicles or solar powered vehicles. The management decided to buy battery powered vehicles because of their lower investment cost despite the requirement of installation of electric battery charging points at various locations in the plant.
Which of the following statements most seriously undermines the decision of the management?


A. Solar powered vehicles do not cause more pollution than battery powered vehicles.
B. The chemical processes in the plant causes much higher pollution than that the diesel-oil driven vehicles produce.
C. The vehicles that go inside the chemical plant need to be fitted with costly spark-proof safety devices.
D. A coal-fired power plant supplies electricity to the chemical plant.
E. Other plants in the vicinity of the chemical plant will continue to use diesel-oil driven vehicles.


A. This statement does not necessarily imply that solar powered vehicles cause less pollution than battery powered vehicles. Hence this statement does not seriously undermine the decision of buying the battery powered vehicles.

B. Even though the chemical processes generate high pollution, replacing diesel-oil powered vehicle with environmentally friendly vehicles would still be beneficial for the environment.

C. The statement does not state that the safety devices are applicable only for battery powered vehicles, but not for solar powered ones. Hence this option does not illustrate a cost disadvantage for the battery powered vehicles compared to solar ones.

D. Correct. The battery powered vehicles may not pollute the environment while being operated, but while charging, the vehicles use electricity that has been produced by burning coal. Hence there is effectively no environmental benefit because the location of burning fossil fuel is transferred from the chemical-plant premises to the power-plant premises. Thus buying battery operated vehicles do not pose any environmental benefit and hence seriously undermines the management’s decision.

E. Even though other plants in the vicinity pollutes the environment, replacing diesel-oil powered vehicle with environmentally friendly vehicles would still be beneficial for the environment.


Answer: D

Doubt: Here we need to undermine the decision of management, which is "decision to buy battery powered vehicles BECAUSE of their lower investment cost

Shouldn't C be the answer?

The managemen't decision is based on lower investment cost. This implies anything that shows the cost might not be low will be the answer.
Selecting the non green reason (coal plants) is more like undermining the decision of the environmentalist.

Shouldn't C be correct option ?
