Problem: Capital punishment in the United States:

Several states have never had capital punishment, the first being Michigan, which abolished it shortly after entering the Union. (However, the United States government executed Tony Chebatoris at the Federal Correctional Institution in Milan, Michigan in 1938.) Article 4, Section 46 of Michigan's fourth Constitution (ratified in 1963; effective in 1964) prohibits any law providing for the penalty of death. Attempts to change the provision have failed. In 2004, a constitutional amendment proposed to allow capital punishment in some circumstances failed to make it on the November ballot after a resolution failed in the legislature and a public initiative failed to gather enough signatures.

 When was Michigan's fifth Constitution ratified?

The Díaz administration made political decisions and took legal measures that allowed the elite throughout Mexico to concentrate the nation's wealth by favoring monopolies. During this time, two-fifths of the state's territory was divided among 17 rich families which owned practically all of the arable land in Chihuahua. The state economy grew at a rapid pace during the Porfiriato; the economy in Chihuahua was dominated by agriculture and mining. The Díaz administration helped Governor Luis Terrazas by funding the Municipal Public Library in Chihuahua City and passing a federal initiative for the construction of the railroad from Chihuahua City to Ciudad Júarez. By 1881, the Central Mexican Railroad was completed which connected Mexico City to Ciudad Juárez. In 1883 telephone lines were installed throughout the state, allowing communication between Chihuahua City and Aldama. By 1888 the telephone services were extended from the capital to the cites of Julimes, Meoqui, and Hidalgo del Parral; the telecommunication network in the state covered an estimated 3,500 kilometers. The need of laborers to construct the extensive infrastructure projects resulted in a significant Asian immigration, mostly from China. Asian immigrants soon become integral to the state economy by opening restaurants, small grocery stores, and hotels. By the end of the Terrazas term, the state experienced an increase in commerce, mining, and banking. When the banks were nationalized, Chihuahua became the most important banking state in Mexico.
Two-fifths of the state's territory was divided between how many families?
A: 17

The TV rights agreement between the Premier League and Sky has faced accusations of being a cartel, and a number of court cases have arisen as a result. An investigation by the Office of Fair Trading in 2002 found BSkyB to be dominant within the pay TV sports market, but concluded that there were insufficient grounds for the claim that BSkyB had abused its dominant position. In July 1999 the Premier League's method of selling rights collectively for all member clubs was investigated by the UK Restrictive Practices Court, who concluded that the agreement was not contrary to the public interest.
Who investigated the agreement between the Premier League and Sky in 2002?

the Office of Fair Trading
