Example Input: Galicia is poetically known as the "country of the thousand rivers" ("o país dos mil ríos"). The largest and most important of these rivers is the Minho, known as O Pai Miño (Father Minho), 307.5 km (191.1 mi) long and discharging 419 m3 (548 cu yd) per second, with its affluent the Sil, which has created a spectacular canyon. Most of the rivers in the inland are tributaries of this fluvial system, which drains some 17,027 km2 (6,574 sq mi). Other rivers run directly into the Atlantic Ocean as Lérez or the Cantabrian Sea, most of them having short courses. Only the Navia, Ulla, Tambre, and Limia have courses longer than 100 km (62 mi).
Example Output: What is Galicia is poetically known as?

Example Input: After the lengthy Iraq disarmament crisis culminated with an American demand that Iraqi President Saddam Hussein leave Iraq, which was refused, a coalition led by the United States and the United Kingdom fought the Iraqi army in the 2003 invasion of Iraq. Approximately 250,000 United States troops, with support from 45,000 British, 2,000 Australian and 200 Polish combat forces, entered Iraq primarily through their staging area in Kuwait. (Turkey had refused to permit its territory to be used for an invasion from the north.) Coalition forces also supported Iraqi Kurdish militia, estimated to number upwards of 50,000. After approximately three weeks of fighting, Hussein and the Ba'ath Party were forcibly removed, followed by 9 years of military presence by the United States and the coalition fighting alongside the newly elected Iraqi government against various insurgent groups.
Example Output: What demand did the US make before invading Iraq in 2003?

Example Input: From an evolutionary-biological perspective, the function of the brain is to provide coherent control over the actions of an animal. A centralized brain allows groups of muscles to be co-activated in complex patterns; it also allows stimuli impinging on one part of the body to evoke responses in other parts, and it can prevent different parts of the body from acting at cross-purposes to each other.
Example Output:
The function of the brain from an evolutionary-biological thought is what?
