Problem: Hunting and gathering was presumably the subsistence strategy employed by human societies beginning some 1.8 million years ago, by Homo erectus, and from its appearance some 0.2 million years ago by Homo sapiens. It remained the only mode of subsistence until the end of the Mesolithic period some 10,000 years ago, and after this was replaced only gradually with the spread of the Neolithic Revolution.
When did human populations begin using hunting-gathering?
The answer is the following: 1.8 million years ago

Problem: In the United Kingdom, a bill is presented for royal assent after it has passed all the required stages in both the House of Commons and the House of Lords. Under the Parliament Acts 1911 and 1949, the House of Commons may, under certain circumstances, direct that a bill be presented for assent despite lack of passage by the House of Lords. Officially, assent is granted by the sovereign or by Lords Commissioners authorised to act by letters patent. It may be granted in parliament or outside parliament; in the latter case, each house must be separately notified before the bill takes effect.
Which Parliamentary Acts allow a bill to be presented for assent even after the House of Lords has refused it?
The answer is the following: Parliament Acts 1911 and 1949

Problem: In 2007, the country with the highest estimated incidence rate of TB was Swaziland, with 1,200 cases per 100,000 people. India had the largest total incidence, with an estimated 2.0 million new cases. In developed countries, tuberculosis is less common and is found mainly in urban areas. Rates per 100,000 people in different areas of the world were: globally 178, Africa 332, the Americas 36, Eastern Mediterranean 173, Europe 63, Southeast Asia 278, and Western Pacific 139 in 2010. In Canada and Australia, tuberculosis is many times more common among the aboriginal peoples, especially in remote areas. In the United States Native Americans have a fivefold greater mortality from TB, and racial and ethnic minorities accounted for 84% of all reported TB cases.
Out of every 100,000 people in Swaziland in 2007, how many were infected with tuberculosis?
The answer is the following: 1,200

Problem: In 2003 a congressional committee called the FBI's organized crime informant program "one of the greatest failures in the history of federal law enforcement." The FBI allowed four innocent men to be convicted of the March 1965 gangland murder of Edward "Teddy" Deegan in order to protect Vincent Flemmi, an FBI informant. Three of the men were sentenced to death (which was later reduced to life in prison), and the fourth defendant was sentenced to life in prison. Two of the four men died in prison after serving almost 30 years, and two others were released after serving 32 and 36 years. In July 2007, U.S. District Judge Nancy Gertner in Boston found the bureau helped convict the four men using false witness account by mobster Joseph Barboza. The U.S. Government was ordered to pay $100 million in damages to the four defendants.
How many of the men died in prison?
The answer is the following:
Two
