PROBLEM: Passage: All equipment must be suitable for a mixed-gender force. Combat helmets, rucksacks, combat boots, and flak jackets are designed to ensure women have the same level of protection and comfort as their male colleagues. The women's uniform is similar in design to the men's uniform, but conforms to the female figure, and is functional and practical. Women are also provided with an annual financial entitlement for the purchase of brassiere undergarments.

SOLUTION: What is a requirement for equipment for the CE?

PROBLEM: Passage: There are fifteen fraternities and seven sororities at the University of Chicago, as well as one co-ed community service fraternity, Alpha Phi Omega. Four of the sororities are members of the National Panhellenic Conference, and ten of the fraternities form the University of Chicago Interfraternity Council. In 2002, the Associate Director of Student Activities estimated that 8–10 percent of undergraduates were members of fraternities or sororities. The student activities office has used similar figures, stating that one in ten undergraduates participate in Greek life.

SOLUTION: Along with 15 sororities, how many fraternities does the U of C have?

PROBLEM: Passage: While Qutb's ideas became increasingly radical during his imprisonment prior to his execution in 1966, the leadership of the Brotherhood, led by Hasan al-Hudaybi, remained moderate and interested in political negotiation and activism. Fringe or splinter movements inspired by the final writings of Qutb in the mid-1960s (particularly the manifesto Milestones, a.k.a. Ma'alim fi-l-Tariq) did, however, develop and they pursued a more radical direction. By the 1970s, the Brotherhood had renounced violence as a means of achieving its goals.

SOLUTION:
Whose ideas did not become increasingly radical during his imprisonment?
