Input: 2008 Sichuan earthquake
Japanese seismologist Yuji Yagi at the University of Tsukuba said that the earthquake occurred in two stages: "The 155-mile Longmenshan Fault tore in two sections, the first one ripping about seven yards, followed by a second one that sheared four yards." His data also showed that the earthquake lasted about two minutes and released 30 times the energy of the Great Hanshin earthquake of 1995 in Japan, which killed over 6,000 people. He pointed out that the shallowness of the epicenter and the density of population greatly increased the severity of the earthquake. Teruyuki Kato, a seismologist at the University of Tokyo, said that the seismic waves of the quake traveled a long distance without losing their power because of the firmness of the terrain in central China. According to reports from Chengdu, the capital of Sichuan province, the earthquake tremors lasted for "about two or three minutes".

Besides the population density, what else contributed to the severity of the quake?
Output: shallowness of the epicenter


Input: Article: Carnaval de Solsona takes place in Solsona, Lleida. It is one of the longest; free events in the streets, and nightly concerts run for more than a week. The Carnival is known for a legend that explains how a donkey was hung at the tower bell − because the animal wanted to eat grass that grew on the top of the tower. To celebrate this legend, locals hang a stuffed donkey at the tower that "pisses" above the excited crowd using a water pump. This event is the most important and takes place on Saturday night. For this reason, the inhabitants are called "matarrucs" ("donkey killers").

Now answer this question: How long can the nightly concerts run for?

Output: more than a week

It would also reorganize its relationship with the Sheffield Scientific School.

Question: When was the Sheffield Scientific School created?
Ans: 1847

The problem: Answer a question about this article:
Criminal justice agencies in England and Wales use at least two separate racial/ethnic classification systems when reporting crime, as of 2010. One is the system used in the 2001 Census when individuals identify themselves as belonging to a particular ethnic group: W1 (White-British), W2 (White-Irish), W9 (Any other white background); M1 (White and black Caribbean), M2 (White and black African), M3 (White and Asian), M9 (Any other mixed background); A1 (Asian-Indian), A2 (Asian-Pakistani), A3 (Asian-Bangladeshi), A9 (Any other Asian background); B1 (Black Caribbean), B2 (Black African), B3 (Any other black background); O1 (Chinese), O9 (Any other). The other is categories used by the police when they visually identify someone as belonging to an ethnic group, e.g. at the time of a stop and search or an arrest: White – North European (IC1), White – South European (IC2), Black (IC3), Asian (IC4), Chinese, Japanese, or South East Asian (IC5), Middle Eastern (IC6), and Unknown (IC0). "IC" stands for "Identification Code;" these items are also referred to as Phoenix classifications. Officers are instructed to "record the response that has been given" even if the person gives an answer which may be incorrect; their own perception of the person's ethnic background is recorded separately. Comparability of the information being recorded by officers was brought into question by the Office for National Statistics (ONS) in September 2007, as part of its Equality Data Review; one problem cited was the number of reports that contained an ethnicity of "Not Stated."
What does IC stand for?
****
The answer:
Identification Code
