Task: Question Generation
Input (English): Background Paragraph: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition. 
Story: Pete and Mike were two brothers. Pete had no health problems, while Mike inherited the sickle cell trait. Mike had adjacent health problems.
Output (English): Which brother did not inherit a genetic disease from one of his parents?
