INFERENCE QUESTIONS: TIPS
In infer questions, the common answer traps are:
a. False contrapositive statements
eg. A implies B (If A then B)
The contrapositive of this statement is always true. False contrapositives are not
necessarily true.
Contrapositive of the above example is Not B implies Not A. (If not B Then not A)
Any other statement is not necessarily true
Tip: For contrapositive, reverse the equation and signs both. Contrapositive of a statement is always true
b. If Universal Information is given. We can only infer (some) from it that will be true
c. If some/particular info is given, we cannot infer ALL and NOT SOME
Very imp: We need to avoid not necessarily true/could be true statements. Infer qs are always of the nature that must be true
Correct Answer choice: B
A:Incorrect because it is the false contrapositive of Mark's logic
B:Correct (Here the Answer can be derived directly from Mark's logic and no contrapositive are required. However it helps to understand this concept for solving more complicated twisted language questions )
Ronald logic= If no fall in interest Then no increase in house price
contrapositive that must be true: If increase in house price then fall in interest
Mark logic= If fall in interest Then increase in prices.
It is a false contrapositive. Hence this logic cannot be inferred from Ronald's statement.
This tells us that Mark has interpreted Ronald's statement incorrectly
C:Incorrect because Ronald's logic and Mark's logic gives an indirect relationship whereas Answer C gives a direct relationship.
D:Incorrect because out of scope of stimulus (significant economic factor)
E:Incorrect because out of scope of stimulus ( next 6 months is not talked about by Mark. He is basing his logic on last one year)
