The occurrence of schizophrenia in the general population is 1 percent

Question

The occurrence of schizophrenia in the general population is 1 percent. If one parent is schizophrenic, however, the incidence rises to 12 percent, and a child with two schizophrenic parents has a 45 percent chance of also suffering from the disease.

Which of the following can be most reasonably inferred from the passage above?

(A) One's risk of developing schizophrenia is greater if one has a schizophrenic grandparent than if one has a grandparent with no diagnosed mental disease.

(B) Early diagnosis of schizophrenia may reduce the severity of the impact of the disease on the patient's life.

(C) One's risk of developing schizophrenia is higher if one has a full sibling with the disease.

(D) Over the past forty years, psychiatrists have advanced significantly in their understanding of the causes and treatments of schizophrenia.

(E) A person's risk of developing schizophrenia is at least partially determined by genetic factors.

(A) One's risk of developing schizophrenia is greater if one has a schizophrenic grandparent than if one has a grandparent with no diagnosed mental disease.
 No such comparison has been done or made, so we cannot infer that.

(B) Early diagnosis of schizophrenia may reduce the severity of the impact of the disease on the patient's life.
 Again no such thing has been discussed.

(C) One's risk of developing schizophrenia is higher if one has a full sibling with the disease.
 Higher than who.? His sibling or higher than the one who doesn't have a sibling suffering from the disease. Comparison is not clear + the relationship of the disease has been maintained between parent and child. Anything beyond that will lead to an assumption.

(D) Over the past forty years, psychiatrists have advanced significantly in their understanding of the causes and treatments of schizophrenia.
 No such thing has been mentioned or discussed.

(E) A person's risk of developing schizophrenia is at least partially determined by genetic factors.
 The data provided suggest that way.

(A) One's risk of developing schizophrenia is greater if one has a schizophrenic grandparent than if one has a grandparent with no diagnosed mental disease.
This may be tempting and according to genetic rules it might even sound true but within the frame of passage we are only given info regarding how parents' situation may affect your chances

(B) Early diagnosis of schizophrenia may reduce the severity of the impact of the disease on the patient's life.
We don't care about diagnosis at all...Irrelevant

(C) One's risk of developing schizophrenia is higher if one has a full sibling with the disease.
As in option A, we are given info regarding how parents' situation may affect your chances

(D) Over the past forty years, psychiatrists have advanced significantly in their understanding of the causes and treatments of schizophrenia.
We don't care about causes or treatments at all...Irrelevant

(E) A person's risk of developing schizophrenia is at least partially determined by genetic factors.
 Correct  normally you have 1% chance of getting schizophrenia but if one of your parents is schizophrenic than your chance is 12% and if both of your parents are schizophrenic than your chance to get this illness is %45. All in all this pattern strongly suggests that there is a genetic role.

The two answer choices are mostly close:

(A) One's risk of developing schizophrenia is greater if one has a schizophrenic grandparent than if one has a grandparent with no diagnosed mental disease.
- Since, the 'One' talked about is already born, and has parents. So it is the parent who will decide the chances of child's schizophrenia not the grandparents.
- Grandparents would have decided the parents's schizophrenia but it has happened now. Now, whatever be the case of parents at present, will decide the chances of child.
- Hence, We can't say based on grandparent's schizophrenia, child's schizophrenia can be decided.

(E) A person's risk of developing schizophrenia is at least partially determined by genetic factors.
- 'At least' and 'Partially' can be inferred by 12% and 45% given in the passage.
