Problem: Please answer a question about the following article about Glacier:
The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20° to 27° north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19˚N and 19˚S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.
Why do mountains between 19N and 19S tend to have snow?
A: precipitation is higher
Problem: Please answer a question about the following article about John von Neumann:
Lothar Wolfgang Nordheim described von Neumann as the "fastest mind I ever met", and Jacob Bronowski wrote "He was the cleverest man I ever knew, without exception. He was a genius." George Pólya, whose lectures at ETH Zürich von Neumann attended as a student, said "Johnny was the only student I was ever afraid of. If in the course of a lecture I stated an unsolved problem, the chances were he'd come to me at the end of the lecture with the complete solution scribbled on a slip of paper." Halmos recounts a story told by Nicholas Metropolis, concerning the speed of von Neumann's calculations, when somebody asked von Neumann to solve the famous fly puzzle:
What did Lecturer Polya think about von Nuemann?
A: Johnny was the only student I was ever afraid of.
Problem: Please answer a question about the following article about Beyoncé:
At the 57th Annual Grammy Awards in February 2015, Beyoncé was nominated for six awards, ultimately winning three: Best R&B Performance and Best R&B Song for "Drunk in Love", and Best Surround Sound Album for Beyoncé. She was nominated for Album of the Year but the award was won by Beck for his Morning Phase album. In August, the cover of the September issue of Vogue magazine was unveiled online, Beyoncé as the cover star, becoming the first African-American artist and third African-American woman in general to cover the September issue. She headlined the 2015 Made in America festival in early September and also the Global Citizen Festival later that month. Beyoncé made an uncredited featured appearance on the track "Hymn for the Weekend" by British rock band Coldplay, on their seventh studio album A Head Full of Dreams (2015), which saw release in December. On January 7, 2016, Pepsi announced Beyoncé would perform alongside Coldplay at Super Bowl 50 in February. Knowles has previously performed at four Super Bowl shows throughout her career, serving as the main headliner of the 47th Super Bowl halftime show in 2013.
Who did Beyonce perform with at Super Bowl 50?
A: Coldplay
Problem: Please answer a question about the following article about Capacitor:
The arrangement of plates and dielectric has many variations depending on the desired ratings of the capacitor. For small values of capacitance (microfarads and less), ceramic disks use metallic coatings, with wire leads bonded to the coating. Larger values can be made by multiple stacks of plates and disks. Larger value capacitors usually use a metal foil or metal film layer deposited on the surface of a dielectric film to make the plates, and a dielectric film of impregnated paper or plastic – these are rolled up to save space. To reduce the series resistance and inductance for long plates, the plates and dielectric are staggered so that connection is made at the common edge of the rolled-up plates, not at the ends of the foil or metalized film strips that comprise the plates.
How are larger value capacitors often constructed?
A:
multiple stacks of plates and disks
