Problem: The primary circadian "clock" in mammals is located in the suprachiasmatic nucleus (or nuclei) (SCN), a pair of distinct groups of cells located in the hypothalamus. Destruction of the SCN results in the complete absence of a regular sleepwake rhythm. The SCN receives information about illumination through the eyes. The retina of the eye contains "classical" photoreceptors ("rods" and "cones"), which are used for conventional vision. But the retina also contains specialized ganglion cells that are directly photosensitive, and project directly to the SCN, where they help in the entrainment (synchronization) of this master circadian clock.
What provides information to the SCN?
The answer is the following: eyes

Problem: Although professional wrestling started out as petty acts in sideshows, traveling circuses and carnivals, today it is a billion-dollar industry. Revenue is drawn from live event ticket sales, network television broadcasts, pay-per-view broadcasts, personal appearances by performers, branded merchandise and home video. Particularly since the 1950s, pro wrestling events have frequently been responsible for sellout crowds at large arenas, including Madison Square Garden, as well as football stadiums, by promotions including the WWE, the NWA territory system, WCW, and AWA. Pro wrestling was also instrumental in making pay-per-view a viable method of content delivery. Annual shows such as WrestleMania, SummerSlam, Royal Rumble, and formerly Bash at the Beach, Halloween Havoc and Starrcade are among the highest-selling pay-per-view programming each year. In modern day, internet programming has been utilized by a number of companies to air web shows, internet pay-per-views (iPPVs) or on-demand content, helping to generate internet-related revenue earnings from the evolving World Wide Web.
Where large places are some of the major wrestling shows held at?
The answer is the following: Madison Square Garden, as well as football stadiums

Problem: In early times, the privilege of papal election was not reserved to the cardinals, and for centuries the person elected was customarily a Roman priest and never a bishop from elsewhere. To preserve apostolic succession the rite of consecrating him a bishop had to be performed by someone who was already a bishop. The rule remains that, if the person elected Pope is not yet a bishop, he is consecrated by the Dean of the College of Cardinals, the Cardinal Bishop of Ostia.
Why did the ceromony of consecrating a bishop have to be preformed by someone who was already a bishop?
The answer is the following: To preserve apostolic succession

Problem: In 1922, Egypt, which had been declared a British protectorate at the outbreak of the First World War, was granted formal independence, though it continued to be a British client state until 1954. British troops remained stationed in Egypt until the signing of the Anglo-Egyptian Treaty in 1936, under which it was agreed that the troops would withdraw but continue to occupy and defend the Suez Canal zone. In return, Egypt was assisted to join the League of Nations. Iraq, a British mandate since 1920, also gained membership of the League in its own right after achieving independence from Britain in 1932. In Palestine, Britain was presented with the problem of mediating between the Arab and Jewish communities. The 1917 Balfour Declaration, which had been incorporated into the terms of the mandate, stated that a national home for the Jewish people would be established in Palestine, and Jewish immigration allowed up to a limit that would be determined by the mandatory power. This led to increasing conflict with the Arab population, who openly revolted in 1936. As the threat of war with Germany increased during the 1930s, Britain judged the support of the Arab population in the Middle East as more important than the establishment of a Jewish homeland, and shifted to a pro-Arab stance, limiting Jewish immigration and in turn triggering a Jewish insurgency.
Britain became more pro-Arab in the 1930s at the expense of which race?
The answer is the following:
Jewish
