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: Jerry and George are two roommates who have lived together since college. They have always gotten along well, have similar hobbies and even are the same height. They both enjoy watching sports and playing videogames, but Jerry also rides his bike several miles each week. George can't stand exercising. Instead, he prefers to lay around relaxing and driving his car if he needs to go somewhere. 
Question: Who has a lower risk of hypertension?
answer:
Jerry.

Background Paragraph: Human populations are on the rise. The human population passed the 7 billion mark in October of 2011, and will pass 8 and 9 billion probably before the middle of the century. All these people will need resources such as places to live, food to eat, and water to drink, and they will use energy and create waste. Essentially, human population growth can effect all other causes of extinction. For example, more people on the Earth means more people contributing to global warming and pollution. More people also means more clearing of land for agriculture and development. Recall that development by humans often causes habitats to be destroyed. This destruction can force species to go extinct, or move somewhere else. 
Story: There are two identical neighboring planets, Krypton and Gotham, inhabited by the same species of creature. Both civilizations utilize the same technology and have the same city structures. However, the creatures on Krypton use substantially more energy than the people on Gotham. Furthermore, the inhabitants of Krypton have started clearing more land than Gotham. 
Question: Which planet has a larger population?
answer:
Krypton.


question:
Background Paragraph: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. 
Story: All marine creatures are not fish. There are some mammals, for example, whales, also live in the water. Rob wants to know more about differences between fish and other non fish creatures in the water. He divided them into two groups, group A and group B. Group A consists of fish, and group B consists of non fish creatures in the water. He started to see the differences between these two groups. 
Question: In which group the females would most likely release high numbers of eggs, group A or group B?
answer:

group A.
