Question: Two neighbors Paul and Dean studied toghether often. this week they got together and Paul started studying about the Gaia hypothesis, while Dean studied Einstein's Theory of Relativity.  Which person studied less about the biosphere?  Hint: The Gaia hypothesis states that the biosphere is its own living organism. The hypothesis suggests that the Earth is self-regulating and tends to achieve a stable state, known as homeostasis . For example the composition of our atmosphere stays fairly consistent, providing the ideal conditions for life. When carbon dioxide levels increase in the atmosphere, plants grow more quickly. As their growth continues, they remove more carbon dioxide from the atmosphere. In this way, the amount of carbon dioxide stays fairly constant without human intervention.
Answer: Dean

Question: The tourist village had two beaches: Coral beach with nice sand and deeper water was preferred by families, and Surfer beach which  had shallow water was a surfer's heaven.  Which beach had waves with a broad and shallow trough?  Hint: When wind waves approach to coast area from deep water, the waves change their heights and lengths. The wave height becomes higher and the wavelength becomes shorter as the wave velocity is slowed when ocean waves approach to the shore. If the water depth is sufficiently shallow, the wave crest become steeper and the trough gets broader and shallower; finally, the ocean waves break at the shore. The motions of wave breaking are different with along to the steepness of shores and waves, and can be categorized by below three types.[11][12]
Answer: Surfer beach

Question: Two neighboring villages were living mostly off the land. Boar village was full of fat people, because they would overeat lots of animal products. Leap village was inhabited by vegetarians and vegans.Their food consumption was moderate.  Which village had fewer people with increased risk of type 2 diabetes?  Hint: 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.
