Critical Reasoning

Human exposure to even low levels of Nuclear radiation drastically increases the likelihood of contracting some form of cancer. according to a research study involving a town near a former nuclear testing site, no person who resided in the town during the testing-which occurred more than 60 years ago-and who was under the age of 10 during the testing lived beyond 50 years of age. However, some of the town's former residents who are now over 50 years old are cancer survivors but resided in the town during the nuclear testing.

Infer

a. some people who resided in the town during the nuclear testing do not remember the testing

b. the cancers contracted by the town's cancer survivors were not caused by exposure to nuclear radiation

c. some of the town's former residents living today were over 10 years of age during the nuclear testing

d the nuclear testing resulted in the emission of lower levels of radiation than initially believed

e some of the town's residents died before turning 50 years of age due to causes other than cancer.

OA: Spoiler Code b

imo B) and C) are the contenders here.

B wins over C) since its a must be true question(inference). There may have been other cancel patients in the town that were under 10 years (got cancer due to a different reason) but since the srgument says that anyone exposed to nuclear radiation and were under 10 years died. So those who are surviving after 50 must have had cancer which was not caused by the radiation.


C) could be true but not must be true

Thoughts welcome!

C shud be correct as it can be correctly infereable.

No one < 10 survived

i.e. some who survived shud be > 10

B is not correct since there is no mention that cancer from nuclear radiation shud always lead to death. So we cannot infer B.

wat is th OA

I still can't get the OA...@ cramya ... cud u plz throw some light on ...how u infered the ans?

MUST BE TRUE QUESTION :

any body below the age of 10 at time of testing died because of cancer..
so the people survived might be above the age of 10 at the time of testing..

choose C

I don't agree with answer B either.

I read the questions for so many times, and I feel that the first sentence only suggests that exposure to radiation increases chances of getting cancer, while the second sentence only suggests that no person (for whatsoever reasons) lives beyond 50 years. Finally, the third sentence only tells me that the person who lives beyond 50 years are cancer survivors.

I don't even know whether the cancer from radiation causes the death of people. I can't decide on B.

I can only deduce C.

It seems to me that it is C
