[Q]: Background: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. Paragraph: Two lakes similar in size are situated 5 miles from one another in the mountains. Both Red and White lake fill with snow water every spring. Red lake is almost emptied in the fall; White lake during the summer. Given the paragraph above, please answer correctly the following question: Which lake had a higher water level during the summer?
****
[A]: Red

[Q]: Background: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. Paragraph: Ben and Andy researched significant greenhouse gasses in Earth's atmosphere. Andy researched more about carbon dioxide, while Ben researched methane gas. Given the paragraph above, please answer correctly the following question: Which researcher studied more about deforestation?
****
[A]: Andy

[Q]: Background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. Paragraph: Two teams of researchers studied the environment in Antarctica. Team Black studied air pollution and the ozone layer, Team Red studied the water. Given the paragraph above, please answer correctly the following question: Which team observed that the culprit are chlorine gasses?
****
[A]: Black

[Q]: 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 wildfire, the one in Texas or the one in Seattle, will have higher intensity?
****
[A]:
the one in Texas
