Problem: Given the question: Background: Beginning in the late 1970's, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels. Paragraph: Ben and Harry were studying about the climatic history of Earth. Ben was more attracted to learning about early Ice Ages, while Harry was curious about the Earth atmosphere and read about ozone depletion and its consequences. Given the paragraph above, please answer correctly the following question: Which person learned less about the danger of CFCs?
++++++++++++++++++++++++++++++++
The answer is:
Ben

Problem: Given the question: Background: Fish mortality is a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death. The mortality can be divided into two types: Natural mortality: the removal of fish from the stock due to causes not associated with fishing. Such causes can include disease, competition, cannibalism, old age, predation, pollution or any other natural factor that causes the death of fish. In fisheries models natural mortality is denoted by (M).[1] Fishing mortality: the removal of fish from the stock due to fishing activities using any fishing gear.[1] It is denoted by (F) in fisheries models. Paragraph: Mary's lake was full of fish, the lake's environment was very healthy. Mary stopped fishing on this lake five years ago and maintained it properly. Jane's lake had high fish mortality both from fishing and pollution, and disease from overstocking. Given the paragraph above, please answer correctly the following question: Which lake had a higher natural mortality?
++++++++++++++++++++++++++++++++
The answer is:
Jane's

Problem: Given the question: Background: Wildfire intensity increases during daytime hours. For example, burn rates of smoldering logs are up to five times greater during the day because of lower humidity, increased temperatures, and increased wind speeds. Sunlight warms the ground during the day and causes air currents to travel uphill, and downhill during the night as the land cools. Wildfires are fanned by these winds and often follow the air currents over hills and through valleys. United States wildfire operations revolve around a 24-hour fire day that begins at 10:00 a.m. because of the predictable increase in intensity resulting from the daytime warmth. Paragraph: Robert was watching the local news when he saw a report about a wildfire. The report stated that there was a brush fire in the southwest part of Texas, where it was currently daytime. When he switched the channel, he saw another report about a different wildfire. This one was a forest fire in the northwest part of Seattle, where it was currently nighttime. Given the paragraph above, please answer correctly the following question: Which area, Texas or Seattle, will have lower humidity?
++++++++++++++++++++++++++++++++
The answer is:
Texas
