question 16:
Conclusion: We should stop doing something
Premises: Because people don't like it.
Well... regardless of whether some people like it or not, why would it does have something to do for abandoning something ? What if the reason why people dont like it is because by doing that thing it would benefit the whole but not some of the particular cases ?
No doubt, A.
Question 17
We are asked to treat the argument as the weaken answer to one of the options as follows. In the other word, what is really happening here is " If the argument is true, then which of the following must be false. "
So, If " one of the following must be true, then it also must be true that the original argument must be false ", and if the original argument must be false is the necessary condition based on the sufficient condition of the must be true answer, then one of our necessary assumptions must never be " If one of the following options must be true, then our original argument must be true and the contrapositive of it.
original argument:
P3: If we do not leave our definitions open to new, unimagined possibilities ---> we would not find or not recognize intelligent life elsewhere in the universe
P2: we can't just decide to define " intelligent life " in some more precise way
P1: we are not sure how differnet from us something might be and still count as intelligent life
C: the question whether intelligent life exists elsewhere in the universe is certainly imprecise
The conclusion of the argument stated clearly that it is certainly impossible to answer the question precisely
Clearly weaken the argument of C.
A. correctly vs imprecise are 2 different concepts.
B. It could be or could not be correctly answer, its about the question itself is imprecise.
D. The core of is based upon meaningless or not, but not precise or not.
E. whether should we spend time or not is totally not relevant to whether the question itself is imprecise or not
