Input: Article: Birds fly at varying altitudes during migration. An expedition to Mt. Everest found skeletons of northern pintail Anas acuta and black-tailed godwit Limosa limosa at 5,000 m (16,000 ft) on the Khumbu Glacier. Bar-headed geese Anser indicus have been recorded by GPS flying at up to 6,540 metres (21,460 ft) while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird. Anecdotal reports of them flying much higher have yet to be corroborated with any direct evidence. Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in landbirds. However most bird migration is in the range of 150 to 600 m (490 to 1,970 ft). Bird strike aviation records from the United States show most collisions occur below 600 m (2,000 ft) and almost none above 1,800 m (5,900 ft).

Now answer this question: Which birds have the highest rates of climb to altitude?

Output: Bar-headed geese Anser indicus

Input: Article: In December 1978, Gaddafi stepped down as Secretary-General of the GPC, announcing his new focus on revolutionary rather than governmental activities; this was part of his new emphasis on separating the apparatus of the revolution from the government. Although no longer in a formal governmental post, he adopted the title of "Leader of the Revolution" and continued as commander-in-chief of the armed forces. He continued exerting considerable influence over Libya, with many critics insisting that the structure of Libya's direct democracy gave him "the freedom to manipulate outcomes".

Now answer this question: After Gaddafi stepped down from the GPC, what title did he take?

Output:
Leader of the Revolution
