Problem: Given the question: Background: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield. Paragraph: Two farms used AM fungi for the plants. Brown farm also decided to grow cover crops on those parcels of land to help mycorrhizal growth. Orange farm didn't grow cover crops. Given the paragraph above, please answer correctly the following question: Which farm provided extended time for AM fungi growth into the spring?
++++++++++++++++++++++++++++++++
The answer is:
Brown

Problem: Given the question: 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. Paragraph: India decided to use fossil fuels to produce their electricity, and Nepal decided to go renewable and use only hydro power to produce their electricity. Given the paragraph above, please answer correctly the following question: Which country released more carbon dioxide into the atmosphere?
++++++++++++++++++++++++++++++++
The answer is:
India

Problem: Given the question: Background: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased. Paragraph: Austria had two distinct climactic regions. The eastern region was exposed to a wet climate and had thriving vegetation, while the western region was exposed to drought. Given the paragraph above, please answer correctly the following question: Which region had fewer plants consistently exposed to drought?
++++++++++++++++++++++++++++++++
The answer is:
eastern
