Problem: I have a new situation: Carrie bought two parcels of farmland. The Northern one had soil with lots of arbuscular mycorrhizal fungi, while the Southern parcel had almost no traces of AM fungi. But I can use this 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. What is an answer for this question: Which parcel had more species of AM fungi in its soil?

A: Northern

Problem: I have a new situation: In the year 1630 during the month of January Captain Cook began his voyage from the port of Calais in Europe, which is in the Northern Hemisphere. His intention was to find the mythical land in the Southern Hemisphere. After about eleven months of sailing, in December 1630, he reached Australia, which is indeed in the Southern Hemisphere. Thinking he finally reached the mythical land, he commenced his return voyage to Europe on June, 1631, He reached Europe in the middle of the following year on July, 1632. But I can use this background: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere. What is an answer for this question: Did Europe receive more or less direct sunlight when Captain Cook started his voyage to the mythical land in 1630?

A: less direct sunlight

Problem: I have a new situation: Two agricultural students had to prepare for exams. Jane had the entomology exam, so she studied about insects. Nora had the chemistry exam, so she studied about alkanes. But I can use this 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. What is an answer for this question: Which student learned less about mayflies?

A: Nora

Problem: I have a new situation: There are two cities, Chien and Marisol, in France that are leaders in the amount of wine they export to the rest of the world. Although they both export the same amount of wine, they use different sources of power to generate their electricity. Chien uses coal to power the city and Marisol uses nuclear power plants to produce electricity. The citizens of both cities are voting on whether to continue their current method of electricity generation. But I can use this background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn't release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. What is an answer for this question: The citizens of which city will generally be more healthy?

A:
Marisol
