The problem: Answer a question about this article:
In 2003, the season expanded to 16 games. There were also several rule changes in this period. In 2005, players were no longer allowed to run out of bounds. The only way for a player to go out of bounds presently is if he is tackled into or deliberately contacts the side boards. This was also the first year the ArenaBowl was played at a neutral site. In 2007, free substitution was allowed, ending the "iron man" era of one-platoon football. And in 2008, the "jack" linebacker was allowed to go sideboard to sideboard without being penalized for "illegal defense".
What year introduced the free substitution rule?
****
The answer: 2007


The problem: Answer a question about this article:
In 1998, Democratic voters dominated areas of the state with a high percentage of racial minorities and transplanted white liberals from the northeastern United States, known colloquially as "snowbirds". South Florida and the Miami metropolitan area are dominated by both racial minorities and white liberals. Because of this, the area has consistently voted as one of the most Democratic areas of the state. The Daytona Beach area is similar demographically and the city of Orlando has a large Hispanic population, which has often favored Democrats. Republicans, made up mostly of white conservatives, have dominated throughout much of the rest of Florida, particularly in the more rural and suburban areas. This is characteristic of its voter base throughout the Deep South.
which party dominates most of the rest of florida 
****
The answer: Republicans, made up mostly of white conservatives, have dominated throughout much of the rest of Florida

Greece is the birthplace of the ancient Olympic Games, first recorded in 776 BC in Olympia, and hosted the modern Olympic Games twice, the inaugural 1896 Summer Olympics and the 2004 Summer Olympics. During the parade of nations Greece is always called first, as the founding nation of the ancient precursor of modern Olympics. The nation has competed at every Summer Olympic Games, one of only four countries to have done so. Having won a total of 110 medals (30 gold, 42 silver and 38 bronze), Greece is ranked 32nd by gold medals in the all-time Summer Olympic medal count. Their best ever performance was in the 1896 Summer Olympics, when Greece finished second in the medal table with 10 gold medals.
Where were the first Olympic games in 775 BC held?
****
The answer: Olympia


The problem: Answer a question about this article:
Antarctica is the coldest of Earth's continents. The coldest natural temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Soviet (now Russian) Vostok Station in Antarctica on 21 July 1983. For comparison, this is 10.7 °C (20 °F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −150 °C (−238 °F) would be needed to produce dry ice snow in Antarctica. Antarctica is a frozen desert with little precipitation; the South Pole itself receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between −80 °C (−112 °F) and −89.2 °C (−128.6 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.
What is Antarctica topographically ?

The answer:
frozen desert
