Problem: Zhejiang:

On Thursday, September 15, 2011, more than 500 people from Hongxiao Village protested over the large-scale death of fish in a nearby river. Angry protesters stormed the Zhejiang Jinko Solar Company factory compound, overturned eight company vehicles, and destroyed the offices before police came to disperse the crowd. Protests continued on the two following nights with reports of scuffles, officials said. Chen Hongming, a deputy head of Haining's environmental protection bureau, said the factory's waste disposal had failed pollution tests since April. The environmental watchdog had warned the factory, but it had not effectively controlled the pollution, Chen added.

What village protested over the large-scale death of fish in a nearby river on September 15, 2011?

A: Hongxiao

Problem: John von Neumann:

Von Neumann's team performed the world's first numerical weather forecasts on the ENIAC computer; von Neumann published the paper Numerical Integration of the Barotropic Vorticity Equation in 1950. Von Neumann's interest in weather systems and meteorological prediction led him to propose manipulating the environment by spreading colorants on the polar ice caps to enhance absorption of solar radiation (by reducing the albedo). thereby inducing global warming. Noting that the Earth was only 6 F (3.3 C) colder during the last glacial period, he noted that the burning of coal and oil "a general warming of the Earth by about one degree Fahrenheit."

On what computer was the first numerical weather forecast produced?
---
A: ENIAC

Problem: Wood:

It is not only the proportion of latewood, but also its quality, that counts. In specimens that show a very large proportion of latewood it may be noticeably more porous and weigh considerably less than the latewood in pieces that contain but little. One can judge comparative density, and therefore to some extent strength, by visual inspection.

What property of wood could we project some indication of by looking at its density?
---
A: strength

Problem: Beer:

The sweet wort collected from sparging is put into a kettle, or "copper" (so called because these vessels were traditionally made from copper), and boiled, usually for about one hour. During boiling, water in the wort evaporates, but the sugars and other components of the wort remain; this allows more efficient use of the starch sources in the beer. Boiling also destroys any remaining enzymes left over from the mashing stage. Hops are added during boiling as a source of bitterness, flavour and aroma. Hops may be added at more than one point during the boil. The longer the hops are boiled, the more bitterness they contribute, but the less hop flavour and aroma remains in the beer.

During what process is the remaining sugar destroyed?

A:
unanswerable
