Problem: Please answer a question about the following article about Cotton:
Historically, in North America, one of the most economically destructive pests in cotton production has been the boll weevil. Due to the US Department of Agriculture's highly successful Boll Weevil Eradication Program (BWEP), this pest has been eliminated from cotton in most of the United States. This program, along with the introduction of genetically engineered Bt cotton (which contains a bacterial gene that codes for a plant-produced protein that is toxic to a number of pests such as cotton bollworm and pink bollworm), has allowed a reduction in the use of synthetic insecticides.
What insect is the most destructive pest in cotton growing in the US?
A: boll weevil

In 1899, the memorial, by the Berlin sculptor Ernst Gustav Herter (1846–1917), finally came to rest, although subject to repeated vandalism, in the Bronx, at 164th Street and the Grand Concourse, or Joyce Kilmer Park near today's Yankee Stadium. (In 1999, it was moved to 161st Street and the Concourse.) In 2007, Christopher Gray of The New York Times described it as "a writhing composition in white Tyrolean marble depicting Lorelei, the mythical German figure, surrounded by mermaids, dolphins and seashells."

Where was Herter's Heine memorial placed in 1899?
Answer: 164th Street and the Grand Concourse, or Joyce Kilmer Park


Problem: In the resulting Battle of Pusan Perimeter (August–September 1950), the U.S. Army withstood KPA attacks meant to capture the city at the Naktong Bulge, P'ohang-dong, and Taegu. The United States Air Force (USAF) interrupted KPA logistics with 40 daily ground support sorties that destroyed 32 bridges, halting most daytime road and rail traffic. KPA forces were forced to hide in tunnels by day and move only at night. To deny matériel to the KPA, the USAF destroyed logistics depots, petroleum refineries, and harbors, while the U.S. Navy air forces attacked transport hubs. Consequently, the over-extended KPA could not be supplied throughout the south. On 27 August, 67th Fighter Squadron aircraft mistakenly attacked facilities in Chinese territory and the Soviet Union called the UN Security Council's attention to China's complaint about the incident. The US proposed that a commission of India and Sweden determine what the US should pay in compensation but the Soviets vetoed the US proposal.
Along with India, what other nation was to determine the how much the US would have to compensate China?
The answer is the following: Sweden


In ring-porous woods each season's growth is always well defined, because the large pores formed early in the season abut on the denser tissue of the year before.
When does the denser tissue the new pores abut come from?
the year before


Input: Bird
Birds have one of the most complex respiratory systems of all animal groups. Upon inhalation, 75% of the fresh air bypasses the lungs and flows directly into a posterior air sac which extends from the lungs and connects with air spaces in the bones and fills them with air. The other 25% of the air goes directly into the lungs. When the bird exhales, the used air flows out of the lung and the stored fresh air from the posterior air sac is simultaneously forced into the lungs. Thus, a bird's lungs receive a constant supply of fresh air during both inhalation and exhalation. Sound production is achieved using the syrinx, a muscular chamber incorporating multiple tympanic membranes which diverges from the lower end of the trachea; the trachea being elongated in some species, increasing the volume of vocalizations and the perception of the bird's size.

Where does the other 25 percent of fresh air go?
Output: directly into the lungs


Problem: Please answer a question about the following article about Glacier:
Even at high latitudes, glacier formation is not inevitable. Areas of the Arctic, such as Banks Island, and the McMurdo Dry Valleys in Antarctica are considered polar deserts where glaciers cannot form because they receive little snowfall despite the bitter cold. Cold air, unlike warm air, is unable to transport much water vapor. Even during glacial periods of the Quaternary, Manchuria, lowland Siberia, and central and northern Alaska, though extraordinarily cold, had such light snowfall that glaciers could not form.
Why can't glaciers form in polar deserts?
A:
they receive little snowfall
