Conclusion : Change in Name of town --> Increase Tourism --> Income of residents will increase immidiately
Assumption : following are the key points to remember for this type of CR question:
The answer choice taht would state what would help the conclusion to hold will be our assumption.
In other words The correct assumption is the choice that would defend the conclusion from any attack. thats why it is defender assumption question.
In order to verify that our answer choice is correct we can do the negation test i.e. Negating the answer choice should make the conclusion fall apart.
Now let us look at each choice:
A. the people in the town are agreeable to the name change -
wrongDoes the agreement among people has anything to do with governing council's decision? No!
B. residents in the town are knowledgeable about comic books -
wrongit is more important that the tourists are knowledgeable about the comic books than the residents are.
C. the town will need to spend only a minimal amount to provide the facilities needed by tourists -
wrongThis option does not tell us anything about income. Even if the residents spend less to fecilitate the tourists it is not certain that their income would increase significantly.
when we Negate the assumption i.e. "the town will need to spend only a HEAVY amount to provide the facilities needed by tourists"
the "what resident spend > what residents earn (income)", which is opposite to the conclusion.
D. other towns have successfully changed their names and developed an increase in tourism -
wrongWhat is true for other towns may or may not be true for Kansas. The reasons can be the facilities, nature and other requirements of tourism may already be in place in those towns but in "kansas" it may not be the case.
E. the per capita cost to the residents of changing the town’s name will be less than the per capita revenue that will result from the increase in tourism -
correctIn order to conclude that income of the residents will increase, It is necessary to assume that the COST to that resident to bring this change would be LESS than the INCOME.
If the cost is high then income will be less, hence negating the choice here breaks the conclusion.
