Problem: American Idol:

There were 13 finalists this season, but two were eliminated in the first result show of the finals.

The next week, Lil Rounds and Anoop Desai were eliminated.

How many contestants were sent home during the first week of finals?

Problem: Antenna (radio):

Antennas more complex than the dipole or vertical designs are usually intended to increase the directivity and consequently the gain of the antenna. This can be accomplished in many different ways leading to a plethora of antenna designs. The vast majority of designs are fed with a balanced line (unlike a monopole antenna) and are based on the dipole antenna with additional components (or elements) which increase its directionality. Antenna "gain" in this instance describes the concentration of radiated power into a particular solid angle of space, as opposed to the spherically uniform radiation of the ideal radiator. The increased power in the desired direction is at the expense of that in the undesired directions. Power is conserved, and there is no net power increase over that delivered from the power source (the transmitter.)

What is different from a monopole antenna with most other antenna types?

A: balanced line

Problem: Switzerland:

In many places in Switzerland, household rubbish disposal is charged for. Rubbish (except dangerous items, batteries etc.) is only collected if it is in bags which either have a payment sticker attached, or in official bags with the surcharge paid at the time of purchase. This gives a financial incentive to recycle as much as possible, since recycling is free. Illegal disposal of garbage is not tolerated but usually the enforcement of such laws is limited to violations that involve the unlawful disposal of larger volumes at traffic intersections and public areas. Fines for not paying the disposal fee range from CHF 200500.

What is the charge for recycling in Switzerland?

A: free

Problem: Web browser:

Microsoft responded with its Internet Explorer in 1995, also heavily influenced by Mosaic, initiating the industry's first browser war. Bundled with Windows, Internet Explorer gained dominance in the web browser market; Internet Explorer usage share peaked at over 95% by 2002.

What was bundled with Internet Explorer?

A:
Windows
