Problem: American Idol:

Season seven premiered on January 15, 2008, for a two-day, four-hour premiere. The media focused on the professional status of the season seven contestants, the so-called 'ringers', many of whom, including Kristy Lee Cook, Brooke White, Michael Johns, and in particular Carly Smithson, had prior recording contracts. Contestant David Hernandez also attracted some attention due to his past employment as a stripper.

Which season seven contestant had worked as a stripper before his time on American Idol?

A: David Hernandez

Problem: Association football:

A standard adult football match consists of two periods of 45 minutes each, known as halves. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents, but is most commonly referred to as stoppage time or injury time, while loss time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. The referee alone signals the end of the match. In matches where a fourth official is appointed, toward the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 10 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.

How long are each period in a non-standard football match?

A: unanswerable

Problem: New Haven, Connecticut:

The New Haven Green is the site of many free music concerts, especially during the summer months. These have included the New Haven Symphony Orchestra, the July Free Concerts on the Green in July, and the New Haven Jazz Festival in August. The Jazz Festival, which began in 1982, is one of the longest-running free outdoor festivals in the U.S., until it was canceled for 2007. Headliners such as The Breakfast, Dave Brubeck, Ray Charles and Celia Cruz have historically drawn 30,000 to 50,000 fans, filling up the New Haven Green to capacity. The New Haven Jazz Festival was revived in 2008 and has been sponsored since by Jazz Haven.

In what year was the New Haven Jazz Festival cancelled, thereby precluding it from being one of the longest running free outdoor festivals in the U.S.?

A: 2007

Problem: Film speed:

where is the maximum possible exposure that does not lead to a clipped or bloomed camera output. Typically, the lower limit of the saturation speed is determined by the sensor itself, but with the gain of the amplifier between the sensor and the analog-to-digital converter, the saturation speed can be increased. The factor 78 is chosen such that exposure settings based on a standard light meter and an 18-percent reflective surface will result in an image with a grey level of 18%/2 = 12.7% of saturation. The factor 2 indicates that there is half a stop of headroom to deal with specular reflections that would appear brighter than a 100% reflecting white surface.

What can too much exposure lead to?

A:
clipped or bloomed camera output
