Problem: Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by availability of food. It occurs mainly in the northern hemisphere, where birds are funnelled on to specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea.
Why do birds primarily migrate?
The answer is the following: availability of food

Input: Multiracial American
After the American Revolutionary War, the number and proportion of free people of color increased markedly in the North and the South as slaves were freed. Most northern states abolished slavery, sometimes, like New York, in programs of gradual emancipation that took more than two decades to be completed. The last slaves in New York were not freed until 1827. In connection with the Second Great Awakening, Quaker and Methodist preachers in the South urged slaveholders to free their slaves. Revolutionary ideals led many men to free their slaves, some by deed and others by will, so that from 1782 to 1810, the percentage of free people of color rose from less than one percent to nearly 10 percent of blacks in the South.

The last slave in New York was freed when?
Output: 1827


Input: Article: Bond and Swann return to London where they meet M, Bill Tanner, Q, and Moneypenny; they intend to arrest C and stop Nine Eyes from going online. Swann leaves Bond, telling him she cannot be part of a life involving espionage, and is subsequently kidnapped. On the way, the group is ambushed and Bond is kidnapped, but the rest still proceed with the plan. After Q succeeds in preventing the Nine Eyes from going online, a brief struggle between M and C ends with the latter falling to his death. Meanwhile, Bond is taken to the old MI6 building, which is scheduled for demolition, and frees himself. Moving throughout the ruined labyrinth, he encounters a disfigured Blofeld, who tells him that he has three minutes to escape the building before explosives are detonated or die trying to save Swann. Bond finds Swann and the two escape by boat as the building collapses. Bond shoots down Blofeld's helicopter, which crashes onto Westminster Bridge. As Blofeld crawls away from the wreckage, Bond confronts him but ultimately leaves him to be arrested by M. Bond leaves the bridge with Swann.

Now answer this question: Where is Bond brought after he is kidnapped?

Output: the old MI6 building


Article: Roughly one-third of the world's population has been infected with M. tuberculosis, with new infections occurring in about 1% of the population each year. However, most infections with M. tuberculosis do not cause TB disease, and 90–95% of infections remain asymptomatic. In 2012, an estimated 8.6 million chronic cases were active. In 2010, 8.8 million new cases of TB were diagnosed, and 1.20–1.45 million deaths occurred, most of these occurring in developing countries. Of these 1.45 million deaths, about 0.35 million occur in those also infected with HIV.

Question: Approximately how many active TB cases were there in 2012?
Ans: 8.6 million


Input: Palermo
During 734 BC the Phoenicians, a sea trading people from the north of ancient Canaan, built a small settlement on the natural harbor of Palermo. Some sources suggest they named the settlement "Ziz." It became one of the three main Phoenician colonies of Sicily, along with Motya and Soluntum. However, the remains of the Phoenician presence in the city are few and mostly preserved in the very populated center of the downtown area, making any excavation efforts costly and logistically difficult. The site chosen by the Phoenicians made it easy to connect the port to the mountains with a straight road that today has become Corso Calatifimi. This road helped the Phoenicians in trading with the populations that lived beyond the mountains that surround the gulf.

Besides Ziz, what other two major settlements belonged to the Phoenicians
Output:
Motya and Soluntum
