Problem: The northern and eastern parts are shallower than 180 meters due to the silt deposited by the Irrawaddy River. This major river flows into the sea from the north through Myanmar. The western and central areas are 900-3,000 meters deep. Less than five percent of the sea is deeper than 3,000 meters , and in a system of submarine valleys east of the Andaman-Nicobar Ridge, the depth exceeds 4,000 meters . The sea floor is covered with pebbles, gravel, and sand. The western boundary of Andaman Sea is marked by volcanic islands and sea mounts, with straits or passages of variable depths that control the entry and exit of water to Bay of Bengal. There occurs a drastic change in depth of water over a small distance of 200km, as one moves from Bay of Bengal to the vicinity of islands and further into the Andaman Sea. The exchange of water between the Andaman Sea and the Bay of Bengal occurs through the straits formed between the Andaman and Nicobar Islands. Out of these, the most important straits are: Preparis Channel , Ten Degree Channel , and Great Channel . PC is the widest but shallowest of the three and separates south Myanmar from north Andaman. TDC is 600 m deep and lies between Little Andaman and Car Nicobar. GC is 1,500 m deep and separates Great Nicobar from Banda Aceh.

Of the three most inportant straits, which is the widest?
Answer: Preparis Channel

Problem: Saint Jean de Brebeuf was a French Jesuit missionary who travelled to New France in 1625. There he worked primarily with the Huron for the rest of his life, except for a few years in France from 1629 to 1633.

In 1649, Brebeuf and another missionary were captured when an Iroquois raid took over a Huron village . Together with Huron captives, the missionaries were ritually tortured and killed on March 16, 1649. Brebeuf was beatified in 1925 and among eight Jesuit missionaries canonized as saints in the Roman Catholic Church in 1930.

How many years elapsed between the time Saint Jean de Brebeuf died and was canonized?
Answer: 281

Problem: In the city, the year 2010 population was spread out with 26.3% under the age of 18, 13.6% from 18 to 24, 30.7% from 25 to 44, 21.1% from 45 to 64, and 7.2% who were 65 years of age or older. The median age was 32 years. For every 100 females, there were 92.5 males. For every 100 females age 18 and over, there were 88.4 males.

Which age group is directly higher (older) than the age group that the median age fell into?
Answer: 45 to 64

Problem: Labor unions generally ignored government employees because they were controlled mostly by the patronage system used by the political parties before the arrival of civil service. Post Office workers did form unions. The National Association of Letter Carriers started in 1889 and grew quickly. By the mid-1960s it had 175,000 members in 6,400 local branches. Several competing organizations of postal clerks emerged starting in the 1890s. Merger discussions dragged on for years, until finally the NFPOC, UNMAPOC and others merged in 1961 as the United Federation of Postal Clerks. Another round of mergers in 1971 produced the American Postal Workers Union . In 2012 the APWU had 330,000 members. The various postal unions did not engage in strikes.

After the United Federation of Postal Workers merger, how many years passed before the mergers produced the American Postal Workers Union?
Answer:
10
