THE CORRECT ANSWER IS D INDEED
See this analogy:-
The easiest way to get into HARVARD MBA is
1) prepare for GMAT
2) Score 770+ in GMAT
3) Send application to HARVARD
These 3 are necessary
conditions to get in HARVARD MBA, but they are not sufficient
enough to guarantee an admission.
What if you score 780 in GMAT but you are only 11 years old and are currently in standard 6 in a school. Can you join HARVARD MBA without a high school or college degree or work experience. NO
So Necessary conditions doesn't means Sufficient condition. They go in both directions and can be often confusing . For example.
Being a fertile, healthy woman is a necessary condition in order to become pregnant.
But can a woman be pregnant without some sort of sperm donor or a male.
So having a willing, fertile, male to donate sperms is required. Adding that to the list will make our condition sufficient
In layman's term always remember
NECCESARY CONDITION = ALL CRITERIAS / RULES/ REQUIREMENTS BUT NO STILL NO GUARANTEE
SUFFICIENT CONDITIONS = GUARANTEE
In the case of Flat earth president claims. He forgets that after being (1) laughed and (2) attacked, only those other theories that were (3) found to be true
were (4) accepted. FOUND TO BE TRUE (3)
IS SUFFICIENT CONDITION
In his case, he is (1) laughed and (2) opposed , now his theories will be found to be FLASE (3) and therefore not accepted (4) SINCE HE DOES NOT FULFILL (3), he will not will be accepted.
THEREFORE D is the CORRECT ANSWER
Flat Earth Society President: It is an accepted philosophical aphorism that all truth passes through three stages: first, it is mocked; second, it is opposed and condemned; third, it is accepted as self-evident. The central claims of my flat earth society were first mocked and now face ferocious opposition, so it is plain enough that they will shortly be accepted as self-evident.
Which of the following best describes the error in the president’s reasoning?
The evidence presented for the president’s conclusion is irrelevant to that conclusion.
The president generalizes from an atypical case.
The phenomenon introduced by the president in support of his principal contention is not a phenomenon covered by the aphorism supplied.
The president mistakes a condition necessary to obtain a result for a condition sufficient to obtain that result.
The president exploits two meaning of the word “truth.”
