I used elimination to reach the answer in this case.
A is a general statement and is neutral so eliminated
B mentions city officials, which is out of scope..argument has nothing to do with view point of city offcials. Eliminated
D same as B, no mention of federal law, moreover, this is a general statement so is not affecting the argument, must be true for all years.
E strengthens the argument instead of weakening it
Hence C must be the answer
I think C strengthens the Conclusion rather than weakening it.
The conclusion is in the First line of the argument -
"The governor claims that the state faces a drought and has implemented new water-use restrictions"Counter premise in the argument says that rainfall this year had been little more than the average of what it had been in 3 previous years.
Hence The reasoning of the argument is the Claim made by Governor is false as there has been more rain this year.
In Order to weaken this reasoning that governor's claim is false, we have to prove that either this year has been more Rains Or anything related to previous years drought.
(C) in this essence strengthens the argument, by claiming that Snow melting has been less so Water is less hence governor's claim is justified.
I think (A) should be the correct response while Weakening the Governor's Claim because If the Governor did not declare drought in previous 3 years when the average rainfall had been less than what has occurred this year, then there is no point in the claim of Drought by the governor that this year be declared a Drought.
