Input: Article: 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.

Now answer this question: Where does migration mainly occur?

Output: the northern hemisphere

Input: Article: Starting in 2010/2011, Hauptschulen were merged with Realschulen and Gesamtschulen to form a new type of comprehensive school in the German States of Berlin and Hamburg, called Stadtteilschule in Hamburg and Sekundarschule in Berlin (see: Education in Berlin, Education in Hamburg).

Now answer this question: What was the combination of Hauptschulen with Realschulen and Gesamtschulen called in Berlin?

Input: Article: Animal tissue consists of elements and compounds ingested, digested, absorbed, and circulated through the bloodstream to feed the cells of the body. Except in the unborn fetus, the digestive system is the first system involved[vague]. Digestive juices break chemical bonds in ingested molecules, and modify their conformations and energy states. Though some molecules are absorbed into the bloodstream unchanged, digestive processes release them from the matrix of foods. Unabsorbed matter, along with some waste products of metabolism, is eliminated from the body in the feces.

Now answer this question: Through what part of the body are nutrients transported to feed cells?

Output:
bloodstream
