Problem: Federal Bureau of Investigation:

During the period from 1993 to 2011, FBI agents fired their weapons on 289 occasions; FBI internal reviews found the shots justified in all but 5 cases, in none of the 5 cases were people wounded. Samuel Walker, a professor of criminal justice at the University of Nebraska Omaha said the number of shots found to be unjustified was "suspiciously low." In the same time period, the FBI wounded 150 people, 70 of whom died; the FBI found all 150 shootings to be justified. Likewise, during the period from 2011 to the present, all shootings by FBI agents have been found to be justified by internal investigation. In a 2002 case in Maryland, an innocent man was shot, and later paid $1.3 million by the FBI after agents mistook him for a bank robber; the internal investigation found that the shooting was justified, based on the man's actions.

On what was the shooting of an innocent Maryland man deemed justified?
---
A: the man's actions

Problem: History of science:

Mathematics: From the earliest the Chinese used a positional decimal system on counting boards in order to calculate. To express 10, a single rod is placed in the second box from the right. The spoken language uses a similar system to English: e.g. four thousand two hundred seven. No symbol was used for zero. By the 1st century BC, negative numbers and decimal fractions were in use and The Nine Chapters on the Mathematical Art included methods for extracting higher order roots by Horner's method and solving linear equations and by Pythagoras' theorem. Cubic equations were solved in the Tang dynasty and solutions of equations of order higher than 3 appeared in print in 1245 AD by Ch'in Chiu-shao. Pascal's triangle for binomial coefficients was described around 1100 by Jia Xian.

What advanced mathematical methods did the Tang dynasty have?
---
A:
Cubic equations
