Task: Question Answering
Input (English): Background Paragraph: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. 
Story: Two brothers took a blood test. The doctor found out that Tim had hemophilia, while his brother Rick had normal blood cells and was healthy. 
Question: Which brother had a higher risk of internal bleeding?
Output (English): Tim.
