Task: Question Generation
Input (English): Background Paragraph: Any unused energy in food—whether it comes from carbohydrates, proteins, or lipids—is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person’s weight (in kilograms) by the square of the person’s height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. 
Story: Two groups of adults were a part of a diet experiment. Group Brown ate 3500 extra calories a day for 3 months, while group Yellow, had a normal diet. Group Brown gained a lot of weight.
Output (English): Which group has a greater chance of getting a BMI above 30.0?
