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.

Inference answer is always true.
A: schizophrenic grandparent may or may not lead to schizophrenic parent ( as chances are 12 and 45 %) so cannot conclude developing schizophrenia is greater if one has a schizophrenic grandparent.
B. Out of scope
C: Sibling with disease
D: Out of scope
E: This can be inferred as it’s a mild answer and it says partially determined by genetic factors.
E is the answer.

[quote="SajjadAhmad"]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. Out of scope. Grandparents are not mentioned in the prompt anywhere. We are interested in the relationship between parents and kids. This is comparing incidence of schizophrenia with "mental disease" too so it's wrong.

B) Early diagnosis of schizophrenia may reduce the severity of the impact of the disease on the patient's life.Out of scope. Not interested in diagnosis

C) One's risk of developing schizophrenia is higher if one has a full sibling with the disease. Again, prompt mentions parental relationship, not siblings'

D) Over the past forty years, psychiatrists have advanced significantly in their understanding of the causes and treatments of schizophrenia. We cannot assume this at all from the prompt given. Any answer choice that asks us to assume something other than what is stated is wrong.

E) A person's risk of developing schizophrenia is at least partially determined by genetic factors. This is correct. Notice the non-extreme language, "at least partially", inference answers that are correct are void of extreme language. Genetic factors are mentioned through the parental relationship. Hence E is correct.
