In 1913 the Zliten mosaic, a Roman mosaic famous for its many scenes from gladiatorial contests, hunting and everyday life, was discovered in the Libyan town of Zliten. In 2000 archaeologists working in Leptis Magna, Libya, uncovered a 30 ft length of five colorful mosaics created during the 1st or 2nd century AD. The mosaics show a warrior in combat with a deer, four young men wrestling a wild bull to the ground, and a gladiator resting in a state of fatigue, staring at his slain opponent. The mosaics decorated the walls of a cold plunge pool in a bath house within a Roman villa. The gladiator mosaic is noted by scholars as one of the finest examples of mosaic art ever seen a "masterpiece comparable in quality with the Alexander Mosaic in Pompeii."
The mosaics uncovered in Libya were from which century?
1st or 2nd century AD

Sometimes overlooked during his life, James Lind, a physician in the British navy, performed the first scientific nutrition experiment in 1747. Lind discovered that lime juice saved sailors that had been at sea for years from scurvy, a deadly and painful bleeding disorder. Between 1500 and 1800, an estimated two million sailors had died of scurvy. The discovery was ignored for forty years, after which British sailors became known as "limeys." The essential vitamin C within citrus fruits would not be identified by scientists until 1932.
When was the first nutrition experiment performed?
1747

During the last three minutes of a half, the penalty for failure to place the ball in play within the 20-second play clock, known as "time count" (this foul is known as "delay of game" in American football), is dramatically different from during the first 27 minutes. Instead of the penalty being 5 yards with the down repeated, the base penalty (except during convert attempts) becomes loss of down on first or second down, and 10 yards on third down with the down repeated. In addition, as noted previously, the referee can give possession to the defence for repeated deliberate time count violations on third down.
What is the penalty for a time count on the first two downs?
loss of down
