Water-system consultant: Rain barrels lowered water bills for detached homes with two occupants and small gardens. Therefore, the same barrels will lower water costs for apartment towers with hundreds of residents. The argument is flawed because it:
A
It takes evidence confined to detached homes with two occupants and small gardens as sufficient for a conclusion about apartment towers with hundreds of residents, which was not part of the observation.
B
It assumes that the best explanation of a result must be the explanation most recently proposed.
C
It treats a comparison with one alternative as though it were a comparison with all possible alternatives.
D
It concludes that a result was intentional merely because the result was beneficial.
E
It mistakes evidence that a tool can be used for evidence that it should be required.
