Researchers compared the brains of recently deceased people who had schizophrenia with those of recently deceased people who did not have .schizophrenia. They found that 35 percent of the former and none of the latter showed evidence of damage to a structure of nerve cells called the subplate. They knew that this damage must have occurred prior to the second fetal trimester, when the subplate controls the development of the connections between the different parts of the brain.

Which one of the following conclusions is most strongly supported by the information above?

(A)  Roughly 35 per cent of people with abnormal brain sub-plates will eventually have schizophrenia. 


(B)  A promising treatment in some cases of schizophrenia is repair of the damaged connections between the different parts of the brain. 


(C)  Some people developed schizophrenia because of damage to the brain subplate after the second fetal trimester. 


(D)  Schizophrenia is determined by genetic factors. 


(E)  There may be a cause of schizophrenia that 
predates birth.

Argument says that damage must have occurred before second fetal trimester or,in other words, before the brain fully develops . So there must be some cause that predates birth.

(E)  There may be a cause of schizophrenia that predates birth.

(A)  Roughly 35 per cent of people with abnormal brain sub-plates will eventually have schizophrenia. 

--The argument states that 35% of people with schizophrenia showed evidence of damage to subplate , but this does not mean that other way round is true.
--Out
(B)  A promising treatment in some cases of schizophrenia is repair of the damaged connections between the different parts of the brain. 

--Out of scope , we cannot introduce any additional information in a conclusion type question.
--Out
(C)  Some people developed schizophrenia because of damage to the brain subplate after the second fetal trimester. 

-- The argument clearly mentions --damage must have occurred prior to the second fetal trimester
--Out
(D)  Schizophrenia is determined by genetic factors. 

--Out of scope.
--Out
(E)  There may be a cause of schizophrenia that 
predates birth.
---This should be the answer .
as 35% would translate to "may"

E for me !!

Hmm, good question. I chose C because I had no idea on what a fetal trimester is! The chances for questions like these to come are pretty less, right?

So E is basically saying: there are other causes of schizo and that these causes are ALSO during pregnancy

i dont get how can it be assumed that the cause MUST be during pregnancy
