The residents of the city of Tibica are supplied water by two local corporations: TMC (Tibica Municipal Corporation) and TWMC (TibicaWater Management Corporation). Under pressure from the government, TMC recently increased its supply of water to the city. Even though TWMC maintained its supply level, the residents complained that their overall supply of water has reduced. Therefore, it seems likely that

Which of the following statements best completes the above passage?

A. In the recent past, the number of regions where the demand for water has increased has been greater than the number of regions where the demand for water has decreased.

B. In some areas of Tibica, the amount of water lost during distribution as a proportion of the amount of water supplied has increased.

C. The complaints made by the residents of Tibica against the corporations that supply water are always driven more by perception than by ground realities.

D. TMWC, which used to supply water uniformly across the city, has rearranged its distribution such that TMWCs water supply in an area is proportional only to the demand in that area.

E. Even though TMC increased its supply of water to the city, it didnt ensure that the supply was proportional to the demand.

This is a classic resolve and explain type. The two facts presented are seemingly paradoxical and we have to pick the answer choice which resolves this paradox. Here is my take on the question.

Nothing to infer this is stated in the passage.

B. In some areas of Tibica, the amount of water lost during distribution as a proportion of the amount of water supplied has increased.
If this is true, the residents complaints can be explained, even though the net supply of water increased, the people of the city received less water.

C. The complaints made by the residents of Tibica against the corporations that supply water are always driven more by perception than by ground realities.
The question stem does not provide any evidence for that, we can't use this statement to complete the argument.

D. TMWC, which used to supply water uniformly across the city, has rearranged its distribution such that TMWCs water supply in an area is proportional only to the demand in that area.
The complaints are not explained in such a case. Moreover, the argument doesn not state the complaints are from which part of the city. This doesn't correct the paradox of the question.

E. Even though TMC increased its supply of water to the city, it didnt ensure that the supply was proportional to the demand.This leaves room for ambiguity. The supply was not proportional to the demand may either imply the supply was more than the demand, or alternatively, it may imply the supply was less than the demand. Only one of which can help resolve the paradox - which means this answer choice is not sufficiently "inferred" by the passage.
Cheers!

A. In the recent past, the number of regions where the demand for water has increased has been greater than the number of regions where the demand for water has decreased.

This essentially means that the overall demand has increased. IRRELEVANT

Quote:
B. In some areas of Tibica, the amount of water lost during distribution as a proportion of the amount of water supplied has increased.

This one says that the relative proportion of the amount of water lost in the distribution channel has increased. CORRECT - Supply increased from TMC's side BUT people are not getting water.

Quote:
C. The complaints made by the residents of Tibica against the corporations that supply water are always driven more by perception than by ground realities.

This means that the basis on which these claims are made is false. NOPE, no way.

Quote:
D. TMWC, which used to supply water uniformly across the city, has rearranged its distribution such that TMWCs water supply in an area is proportional only to the demand in that area.

Firstly, we are not concerned with TMWC. Secondly, the stem clearly states that the supply of TMWC is unchanged. INCORRECT

Quote:
E. Even though TMC increased its supply of water to the city, it didn't ensure that the supply was proportional to the demand.

The stem says the overall supply has decreased. This option says that supply has increased but is not proportional to the demand. REJECT
