Q: John and Mary were studying insects. John liked to study insects that never eat, while Mary decided to study insects that are very healthy eaters. Given the paragraph above, please answer correctly the following question: Which person studied more about mayflies? Hint: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried.
A: John

Q: Two brothers have a piece of land each, situated 2 miles from each other. Jim's land is not very fertile because it has clay soil with a high pH, while Bob's land has very fertile soil and has a good productivity on it. Given the paragraph above, please answer correctly the following question: Which of the two pieces of land is less alkaline? Hint: Alkali, or Alkaline, soils are clay soils with high pH (> 8.5), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell[1] and difficult to clarify/settle. They derive their name from the alkali metal group of elements, to which sodium belongs, and which can induce basicity. Sometimes these soils are also referred to as alkaline sodic soils. Alkaline soils are basic, but not all basic soils are alkaline.
A: Bob's

Q: Two sisters attended a wedding. Ann got very sick early on, after eating the appetizer. She was infected with norovirus and with hepatitis A. Bianca danced for a while then ate the main course and fell ill. She found out she was infected with Giardia and trichinella. Given the paragraph above, please answer correctly the following question: Which sister didn't have a type of roundworm? Hint: Common foodborne viruses include norovirus and hepatitis A virus. Norovirus, which causes inflammation of the stomach and intestines, has been a recent issue on cruise ships, infecting hundreds of passengers and crew on certain voyages. Hepatitis A causes inflammation of the liver, which is treated with rest and diet changes. Parasites are tiny organisms that live inside another organism. Giardia is a parasite spread through water contaminated with the stools of people or animals who are infected. Food preparers who are infected with parasites can also contaminate food if they do not thoroughly wash their hands after using the bathroom and before handling food. Trichinella is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game.
A: Ann

Q: David was studying the processes involved in a machine. He collected a simple machine. He tagged it as case A. To compare it with compound machines, he collected two compound machines, case B and case C. Case B is a compound machine with few simple machines. And, case C is a compound machine with many simple machines. Given the paragraph above, please answer correctly the following question: Would case B have greater or smaller mechanical advantage than case C? Hint: The mechanical advantage of a machine is the factor by which it changes the force applied to the machine. Many machines increase the force applied to them, and this is how they make work easier. Compound machines tend to have a greater mechanical advantage than simple machines. That's because the mechanical advantage of a compound machine equals the product of the mechanical advantages of all its component simple machines. The greater the number of simple machines it contains, the greater its mechanical advantage tends to be.
A:
smaller
