Critical Reasoning

If weak manufacturing sectors resulted in high rates of unemployment, states with the weakest manufacturing sectors would also have the highest rates of unemployment. In reality, however, when manufacturing statistics are adjusted so that different states are reliably comparable to each other, there is no correlation between weak manufacturing sectors and high rates of unemployment.

If the statements above are all true, which of the following can be properly inferred on the basis of them?

(A) The weaker a state's manufacturing sector, the more likely that state is to offer unemployment insurance.
(B) If a state's manufacturing sector becomes stronger, its unemployment rate will not necessarily fall.
(C) It is not possible to compare the manufacturing statistics of two states reliably.
(D) When states are ranked in terms of total economic output from largest to smallest, the smallest states generally have the strongest manufacturing sectors and the lowest rates of unemployment.
(E) States with the highest rates of unemployment never have especially weak manufacturing sectors.

OA [spoiler]B, what is wrong with C????[/spoiler]

The text give us reason to believe that C is false: by adjusting statistics, states can be reliably compared in terms of manufacturing sector strength

IMO B C seems to be little too extreme

Moreover B is contra positive A -------B then usually answer is not B then Not A (here A---B is causal relationship) hope this helps
