Problem: Canadian Armed Forces:

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.

What is a requirement for equipment for the CAF?
---
A: equipment must be suitable for a mixed-gender force

Problem: American Idol:

This season saw the first Idol Gives Back telethon-inspired event, which raised more than $76 million in corporate and viewer donations. No contestant was eliminated that week, but two (Phil Stacey and Chris Richardson) were eliminated the next. Melinda Doolittle was eliminated in the final three.

How much money did the Idol Gives Back event raise in 2007?
---
A: $76 million

Problem: Russian language:

Among the first to study Russian dialects was Lomonosov in the 18th century. In the 19th, Vladimir Dal compiled the first dictionary that included dialectal vocabulary. Detailed mapping of Russian dialects began at the turn of the 20th century. In modern times, the monumental Dialectological Atlas of the Russian Language ( [dlktlitskj atls ruskv jzka]), was published in three folio volumes 19861989, after four decades of preparatory work.

When did Lomonosov map Russian dialects?
---
A: unanswerable

Problem: Antenna (radio):

As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.

What is one piece that makes up an antenna system?

A:
