Question
In the question below, a situation is given, followed by
two statements that may or may not be concluded from the situation. Select the option that contains the conclusion(s) that follows. While some genes are active in both schizophrenia and autism, they are much more active in the latter. There are signs that brain cell communication was affected in three diseases: autism, depression and bipolar disorder. 1. People who suffer from schizophrenia are often also patients of autism. 2. Both schizophrenia and autism are diseases that have a genetic basis.Solution
1 cannot be concluded from the given situation as we have insufficient data to assume that simply because there is overlaps of gene activity in both diseases, patients of one disease also suffer from the other. 2 can be concluded since the occurrences of the diseases are correlated with changes in gene activity. Thus, (b) is the right answer.
