IMO - AOne catch in this question is finding the correct conclusion. Here we need to apply the
therefore test to find the correct conclusion.
[2 potential conclusion as per below :
a) Clearly, the pollution of the beaches is doubly harmful.
b) Therefore, it is extremely important that the authorities keep the beaches clean.]
Now apply the therefore test.
Because the pollution of the beaches is doubly harmful therefore it is extremely important that the authorities keep the beaches clean.
( Makes sense)Because it is extremely important that the authorities keep the beaches clean therefore the pollution of the beaches is doubly harmful
(Doesn't make sense)This gives us the conclusion as
it is extremely important that the authorities keep the beaches clean.
Now let's check all the options.
A - 1st BF is the intermediate conclusion and position favored by the argument. 2nd BF is the premise supporting the intermediate conclusion. -
CorrectB- The first is an assumption; the second is a premise which adds information to a previous premise. - Assumptions are not stated directly -
EliminateC- The first is a conclusion; the second is an inference based on a previous premise. - First is a intermediate conclusion not the conclusion -
EliminateD- The first is a premise; the second is a conclusion based on a previous premise. - Second is not a conclusion, it is a premise supporting the 1st BF. -
EliminateE- The first is the general position of the argument; the second is an additional piece of evidence which stands in apparent contradiction to the previous information. - Second is not against the conclusion or any previous information -
Eliminate.
