Q13 - Pollution is a problem wherever there

[mshinners]

Question Type:
Match the Reasoning

Stimulus Breakdown:
Definitely a conditional Matching question (""wherever"" is a sufficient condition indicator).

Indifferent people → Pollution
Pollution → Nature's balance harmed
______________________________
Indifferent people → Nature's balance harmed

The conditional logic all checks out, so this is a valid argument with the structure:
A→B + B→C = A→C

Answer Anticipation:
Not much to anticipate - let's find an answer that has two conditionals that chain together.

Correct Answer:
A

Answer Choice Analysis:
(A) Bingo:
Chocolate → High in calories
High in calories → Fattening
__________________________
Chocolate → Fattening

(B) The first two statements share a necessary condition, which means we can't chain them together.

(C) The first two statements share a sufficient condition, which means we can't chain them together.

(D) The first two statements match, but the conclusion is an illegal reversal. This argument is invalid, and it therefore doesn't match the argument:
Chocolate → High in calories
High in calories → Fattening
____________________________
Fattening → Chocolate

(E) That "many" kills this answer - it's a relevant logical feature that doesn't match up. You shouldn't have read past it!

Takeaway/Pattern: Get that practice in for conditional logic! Use our Arcade and download our flashcards. If you get good at it, you can quickly analyze answers like B and C without actually diagramming them out (same with D, though it helps to diagram it to prove it's wrong).
