One of the most popular shows on CBC Television is the weekly Saturday night broadcast of NHL hockey games, Hockey Night in Canada. It has been televised by the network since 1952. During the NHL lockout and subsequent cancellation of the 2004-2005 hockey season, CBC instead aired various recent and classic movies, branded as Movie Night in Canada, on Saturday nights. Many cultural groups criticized this and suggested the CBC air games from minor hockey leagues; the CBC responded that most such broadcast rights were already held by other groups, but it did base each Movie Night broadcast from a different Canadian hockey venue. Other than hockey, CBC Sports properties include Toronto Raptors basketball, Toronto FC Soccer, and various other amateur and professional events.

Nasser's return to Egypt coincided with Husni al-Za'im's Syrian coup d'etat. Its success and evident popular support among the Syrian people encouraged Nasser's revolutionary pursuits. Soon after his return, he was summoned and interrogated by Prime Minister Ibrahim Abdel Hadi regarding suspicions that he was forming a secret group of dissenting officers. According to secondhand reports, Nasser convincingly denied the allegations. Abdel Hadi was also hesitant to take drastic measures against the army, especially in front of its chief of staff, who was present during the interrogation, and subsequently released Nasser. The interrogation pushed Nasser to speed up his group's activities.
What people had a coup around the time Nasser returned to Egypt?
A: Syrian

The Earth of the early Archean (4,000 to 2,500 million years ago) may have had a different tectonic style. During this time, the Earth's crust cooled enough that rocks and continental plates began to form. Some scientists think because the Earth was hotter, that plate tectonic activity was more vigorous than it is today, resulting in a much greater rate of recycling of crustal material. This may have prevented cratonisation and continent formation until the mantle cooled and convection slowed down. Others argue that the subcontinental lithospheric mantle is too buoyant to subduct and that the lack of Archean rocks is a function of erosion and subsequent tectonic events.
What was recycled more as the earth cooled?
A: unanswerable

Insects are the only group of invertebrates to have developed flight. The evolution of insect wings has been a subject of debate. Some entomologists suggest that the wings are from paranotal lobes, or extensions from the insect's exoskeleton called the nota, called the paranotal theory. Other theories are based on a pleural origin. These theories include suggestions that wings originated from modified gills, spiracular flaps or as from an appendage of the epicoxa. The epicoxal theory suggests the insect wings are modified epicoxal exites, a modified appendage at the base of the legs or coxa. In the Carboniferous age, some of the Meganeura dragonflies had as much as a 50 cm (20 in) wide wingspan. The appearance of gigantic insects has been found to be consistent with high atmospheric oxygen. The respiratory system of insects constrains their size, however the high oxygen in the atmosphere allowed larger sizes. The largest flying insects today are much smaller and include several moth species such as the Atlas moth and the White Witch (Thysania agrippina).
Wings from modified gills is from what origin?
A:
pleural origin
