Q: Given the background: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. and the situation: Harry and Kim studied ancient humans. Kim studied a 15000 year-old settlement, before humans invented agriculture, while Harry studied a 5000 year-old village. Answer the following question: Which student studied about a village that had a higher death rate?
A: Harry

Question: Given the background: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change. and the situation: Two different countries produced their electricity using different methods. Burma used fossil fuels such as coal and oil, while Bhutan used renewable energy sources. Answer the following question: Which country released less carbon dioxide into the atmosphere ?
Answer: Bhutan

[Q]: Given the background: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed. and the situation: Two frogs are being examined in a laboratory. Frog X was found in a pond in the forest and has a parasite in it. Frog Y was found just outside the laboratory and is missing one eye. The employees at the lab weren't planning on analyzing any frogs, but when they found the one outside their front door they changed their mind. Answer the following question: Which frog is less likely to contract an illness?
****
[A]: Frog Y

input: Please answer the following: Given the background: 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. and the situation: 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. Answer the following question: Which person studied less about mayflies?
++++++++++
output: Mary

Please answer this: Given the background: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. and the situation: Two engineering students learned about petroleum products, While Dan learned more about plastics, Jim learned about fuels. Answer the following question: Which student learned less about fuels for trains?
++++++++
Answer: Dan

Question: Given the background: Arbuscular mycorrhizal fungi vary across many environmental gradients. Their tolerance to freezing and drying is known to shift between AM fungal taxa. AM fungi become less prevalent and diverse at higher soil nutrient and moisture concentrations, presumably because both plants allocate less carbon to AM fungi and AM fungi reallocate their resources to intraradical hyphae in these environmental conditions. Over the long term, these environmental conditions can even create local adaptation between plant hosts, AM fungi and the local soil nutrient concentrations. and the situation: Greg and Paul were two neighbors. They were both into mycology. Greg researched AM fungi, while Paul studied other types of mycorrhizal fungi. Answer the following question: Which researcher learned more about the prevalence of AM fungi at lower soil moisture concentrations?
Answer:
Greg
