Task: Question Answering
Input (English): Background Paragraph: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. 
Story: Two teams of researchers studied different diseases. team Alpha studied people with cholesterol, while team Beta studied people with Parkinson's disease. 
Question: Which team studied fewer people with cholesterol and other materials deposited on the interior of the arterial wall?
Output (English): Beta.
