Problem: Punjab, Pakistan:

Maharaja Ranjit Singh's death in the summer of 1839 brought political chaos and the subsequent battles of succession and the bloody infighting between the factions at court weakened the state. Relationships with neighbouring British territories then broke down, starting the First Anglo-Sikh War; this led to a British official being resident in Lahore and the annexation in 1849 of territory south of the Satluj to British India. After the Second Anglo-Sikh War in 1849, the Sikh Empire became the last territory to be merged into British India. In Jhelum 35 British soldiers of HM XXIV regiment were killed by the local resistance during the Indian Rebellion of 1857.[citation needed]

When did Ranjit Singh die?

A: summer of 1839


Problem: Traditionally, major college basketball teams began their seasons with a few exhibition games. They played travelling teams made up of former college players on teams such as Athletes in Action or a team sponsored by Marathon Oil. On occasion before 1992, when FIBA allowed professional players on foreign national teams, colleges played those teams in exhibitions. However, in 2003, the National Collegiate Athletic Association banned games with non-college teams. Some teams have begun scheduling exhibition games against teams in NCAA Division II and NCAA Division III, or even against colleges and universities located in Canada. Major college basketball teams still travel to other countries during the summer to play in exhibition games, although a college team is allowed one foreign tour every four years, and a maximum of ten games in each tour.
When did the FIBA stop allowing pros on foreign national teams?

Answer: 1992
