Input: Canadian football
Before scrimmage, an official places the ball at the spot it was at the stop of clock, but no nearer than 24 yards from the sideline or 1 yard from the goal line. The line parallel to the goal line passing through the ball (line from sideline to sideline for the length of the ball) is referred to as the line of scrimmage. This line is similar to "no-man's land"; players must stay on their respective sides of this line until the play has begun again. For a scrimmage to be valid the team in possession of the football must have seven players, excluding the quarterback, within one yard of the line of scrimmage. The defending team must stay a yard or more back from the line of scrimmage.

How many players must the team with possession place near the line of scrimmage?
Output: seven

Input: Greece
By the end of the month, the Peloponnese was in open revolt against the Ottomans and by October 1821 the Greeks under Theodoros Kolokotronis had captured Tripolitsa. The Peloponnesian revolt was quickly followed by revolts in Crete, Macedonia and Central Greece, which would soon be suppressed. Meanwhile, the makeshift Greek navy was achieving success against the Ottoman navy in the Aegean Sea and prevented Ottoman reinforcements from arriving by sea. In 1822 and 1824 the Turks and Egyptians ravaged the islands, including Chios and Psara, committing wholesale massacres of the population. This had the effect of galvanizing public opinion in western Europe in favor of the Greek rebels.[page needed]

Who was the leader of the Greek revolt in 1821?
Output: Theodoros Kolokotronis

Input: Botany
Unlike animals, many plant cells, particularly those of the parenchyma, do not terminally differentiate, remaining totipotent with the ability to give rise to a new individual plant. Exceptions include highly lignified cells, the sclerenchyma and xylem which are dead at maturity, and the phloem sieve tubes which lack nuclei. While plants use many of the same epigenetic mechanisms as animals, such as chromatin remodeling, an alternative hypothesis is that plants set their gene expression patterns using positional information from the environment and surrounding cells to determine their developmental fate.

What happens when a plant remains totipotent?
Output: ability to give rise to a new individual plant

Input: Intellectual property
The term can be found used in an October 1845 Massachusetts Circuit Court ruling in the patent case Davoll et al. v. Brown., in which Justice Charles L. Woodbury wrote that "only in this way can we protect intellectual property, the labors of the mind, productions and interests are as much a man's own...as the wheat he cultivates, or the flocks he rears." The statement that "discoveries are...property" goes back earlier. Section 1 of the French law of 1791 stated, "All new discoveries are the property of the author; to assure the inventor the property and temporary enjoyment of his discovery, there shall be delivered to him a patent for five, ten or fifteen years." In Europe, French author A. Nion mentioned propriete intellectuelle in his Droits civils des auteurs, artistes et inventeurs, published in 1846.

What year did the "discoveries are property" concept appear in French law?
Output:
1791
