Intending to become self-sufficient in energy production

Question

Intending to become self-sufficient in energy production, the government of Taggar has issued minimum energy efficiency requirements for all household appliances, electric vehicles, lighting fixtures, and all other electric devices. About eighty percent of the total electricity produced in Taggar is generated from fuel. The more energy-efficient an electric device is, the less fuel is needed to power it over time. As Taggarans replace their old electric devices with ones compliant with the new requirements, annual consumption of fuel for energy generation is likely to decrease in Taggar.

Which of the following, if true, most seriously weakens the argument?

A. In Taggar, domestically produced energy is more expensive than imported energy.
B. The Taggaran government did not institute the new energy-efficiency requirements for the purpose of fuel conservation.
C. Taggarans who get more energy-efficient electric devices tend to use them more than they did the older devices.
D. The new regulations need no specific change in the composition of materials used to construct electric devices in Taggar.
E. Some energy-efficiency measurement devices mandated in Taggar indicate electric devices to be less energy-efficient than the devices actually are.

No brainer, option C directly weakens the argument.

Adit_ · Answer

Pre thinking:
1)Other non-domestic industries compensate with higher fuel consumption for any lowering of usage by domestic households.
2) The domestic households beginto use it more making the possiblity of the fuel consumption to be more or at par with the usage before.

Option C perfectly states the 2nd pre thinking.

Answer:  Option C

Answer: C

The argument assumes greater efficiency will lead to less fuel consumption.
But if people use efficient devices more, total electricity usage may stay the same or increase.
Thus fuel consumption may not decrease, weakening the argument.

country wants to be self sufficient in energy production. so they issues minimum energy efficiency requirement for different tools. 
 80% electricity is produced from fuel at moment. 
 the more energy efficient the tool, less fuel is needed. 
 they are replacing old electric devices with new ones. 
 conclusion= annual consumption of fuel is likely to decrease.

A. In Taggar, domestically produced energy is more expensive than imported energy. 
 then it make sense to apply this rule and become more self sufficient. so this strengthen it.

B. The Taggaran government did not institute the new energy-efficiency requirements for the purpose of fuel conservation. 
 no matter what the intentions were but their goal can still be met. so reject.

C. Taggarans who get more energy-efficient electric devices tend to use them more than they did the older devices. 
 if they are going to use more then the intended effect will not happen. may be the fuel consumption still stays the same if not increase. clear weakener.

D. The new regulations need no specific change in the composition of materials used to construct electric devices in Taggar. 
 but if they are more energy efficient then who care about the same materials.

E. Some energy-efficiency measurement devices mandated in Taggar indicate electric devices to be less energy-efficient than the devices actually are. 
 that means existing ones are better than they thought. so they will save more and now with the new law, more fuel will be saves. so this actually helps the plan. so reject.
