PROBLEM: Passage: In July 1977, General Zia-ul-Haq overthrew Prime Minister Zulfiqar Ali Bhutto's regime in Pakistan. Ali Bhutto, a leftist in democratic competition with Islamists, had announced banning alcohol and nightclubs within six months, shortly before he was overthrown. Zia-ul-Haq was much more committed to Islamism, and "Islamization" or implementation of Islamic law, became a cornerstone of his eleven-year military dictatorship and Islamism became his "official state ideology". Zia ul Haq was an admirer of Mawdudi and Mawdudi's party Jamaat-e-Islami became the "regime's ideological and political arm". In Pakistan this Islamization from above was "probably" more complete "than under any other regime except those in Iran and Sudan," but Zia-ul-Haq was also criticized by many Islamists for imposing "symbols" rather than substance, and using Islamization to legitimize his means of seizing power. Unlike neighboring Iran, Zia-ul-Haq's policies were intended to "avoid revolutionary excess", and not to strain relations with his American and Persian Gulf state allies. Zia-ul-Haq was killed in 1988 but Islamization remains an important element in Pakistani society.

SOLUTION: When was the regime in Pakistan accepted by General Zia-ul-Haq?

PROBLEM: Passage: Aerobic gymnastics (formally Sport Aerobics) involves the performance of routines by individuals, pairs, trios or groups up to 6 people, emphasizing strength, flexibility, and aerobic fitness rather than acrobatic or balance skills. Routines are performed for all individuals on a 7x7m floor and also for 12–14 and 15-17 trios and mixed pairs. From 2009, all senior trios and mixed pairs were required to be on the larger floor (10x10m), all groups also perform on this floor. Routines generally last 60–90 seconds depending on age of participant and routine category.

SOLUTION: What involves the performance of routines by groups of up to 10 people?

PROBLEM: Passage: On the field at the beginning of a play are two teams of 12 (unlike 11 in American football). The team in possession of the ball is the offence and the team defending is referred to as the defence. Play begins with a backwards pass through the legs (the snap) by a member of the offensive team, to another member of the offensive team. This is usually the quarterback or punter, but a "direct snap" to a running back is also not uncommon. If the quarterback or punter receives the ball, he may then do any of the following:

SOLUTION:
What is the term for a team with control of the quarterback?
