Task: Question Answering
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 men go into the doctor's office for a checkup. Stepping on the scale, the doctor weighs each of them. Tom has an average and healthy weight. However, Joe has a weight that indicates he is obese. 
Question: Will Joe's risk of hypertension increase or decrease if he gains weight?
Output (English): increase.
