Two different cages of rabbits were given injections of mild toxins. In addition, the first cage was also exposed to cold temperature; three-fourths of the rabbits in this cage became sick. Only one-fifth of the rabbits in the normal temperature cage became sick. The lab technicians concluded that cold temperature increases the likelihood of illness in rabbits.

The technicians' conclusion logically depends on which of the following assumptions?


(A) The exposure to cold temperature acted as a catalyst for the toxins which made more rabbits in the first cage sick.

(B) The toxins given to the rabbits in the two cages were of varying strength.

(C) Injecting the rabbits with toxins made them sick.

(D) Even without the exposure to cold temperature, the rabbits in the first cage would have probably gotten sick.

(E) Even exposing rabbits to slight variances in temperature is likely to induce illness.

I would go for A.

b) The toxins given to the rabbits in the two cages were of varying strength.
Doesn't help the conclusion.

c) Injecting the rabbits with toxins made them sick.
If so, then all the rabbits in both cages should have fallen sick.

d) Even without the exposure to cold temperature, the rabbits in the first cage would have probably gotten sick.
Irrelevant.

e) Even exposing rabbits to slight variances in temperature is likely to induce illness.
If so, all the rabbits in the first cage should have fallen sick.

a) The exposure to cold temperature acted as a catalyst for the toxins which made more rabbits in the first cage sick.
This seems to be the best answer.

I was down to A and C. C seems too broad to me.

So will go with A.

I would go with A.The cold weather stimulated the illness among the rabbits.

between A and C.

conclusion: cold temperature increases the likelihood of illness in rabbits. (note:toxins are not mentioned here)

c) Injecting the rabbits with toxins made them sick.
seems unrelated to the conclusion

a) The exposure to cold temperature acted as a catalyst for the toxins which made more rabbits in the first cage sick.
links cold and toxins. hence looks a better option.

OA please...

OA is A indeed.It can be assumed that the combination of cold temperature and the toxin makes more rabbits sick.All other choices can be true on a stand-alone basis.However,they do not support the technicians conclusion.

A is correct!

a) Correct - more rabbits became sick in the first cage than the second (assuming the cold weather was the only variation)
b) outside the scope
c) No, because some of the rabbits who were injected did not get sick from the toxins (as indicated by those who were not subjected to cold temperature)
d) No, not all of the rabbits who became sick in the first cage would have become sick had they not been exposed to cold temp
e) No because one became sick in the cage that was not subjected to cold temperatures

A seems probable choice here.
Rabbits in both the cages were injected with Toxins. The 1st cage was exposed to cold temperatures and hence the occurrence of sickness was 75%. The conclusion concludes that its the cold temperature which triggers sickness in Rabbits.

The assumption is that there is nothing else that could have resulted in the effect (rabbits contracting sickness) other than "cold temperature". This is affirmed by Option A.

Hope this helps.

The OA is A.

OFFICIAL EXPLANATION:



If more rabbits became sick in the cage where they were exposed to colder temperature, as opposed to the warmer cage where fewer rabbits became sick, after being injected with the same toxins, it can be assumed that the combination of cold temperature and the toxin makes more rabbits sick. Choice A is the best answer. All other choices can be true on a stand-alone basis. However, they do not support the technicians' conclusion.
