Question: Two groups of people followed different diets. Group A was comprised of vegans, while group B had a regular diet, with the mention they ate a lots of fatty foods and fast-food. Given the paragraph above, please answer correctly the following question: Which group was more at risk for cardiovascular disease? Hint: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis.

Question: Two sisters both had allergies. Ann had mild allergies, while Jo had to be very careful because she experienced severe allergic reactions before. Given the paragraph above, please answer correctly the following question: Which sister didn't require an injection of the hormone epinephrine? Hint: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response.

Question: Two groups of students studied Biology. Group One studied mammals, while Group Two studied birds. They focused on the respiratory system. Given the paragraph above, please answer correctly the following question: Which group of students learned less about alveoli? Hint: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court!
