Input: Read this: The first part of the campaign went well, with John outmanoeuvring the forces under the command of Prince Louis and retaking the county of Anjou by the end of June. John besieged the castle of Roche-au-Moine, a key stronghold, forcing Louis to give battle against John's larger army. The local Angevin nobles refused to advance with the king; left at something of a disadvantage, John retreated back to La Rochelle. Shortly afterwards, Philip won the hard-fought battle of Bouvines in the north against Otto and John's other allies, bringing an end to John's hopes of retaking Normandy. A peace agreement was signed in which John returned Anjou to Philip and paid the French king compensation; the truce was intended to last for six years. John arrived back in England in October.
Question: Who won the battle of Bouvines?

Output: Philip

QUES: The number of species invasions has been on the rise at least since the beginning of the 1900s. Species are increasingly being moved by humans (on purpose and accidentally). In some cases the invaders are causing drastic changes and damage to their new habitats (e.g.: zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. Others report confounding evidence that occasionally suggest that species-rich communities harbor many native and exotic species simultaneously while some say that diverse ecosystems are more resilient and resist invasive plants and animals. An important question is, "do invasive species cause extinctions?" Many studies cite effects of invasive species on natives, but not extinctions. Invasive species seem to increase local (i.e.: alpha diversity) diversity, which decreases turnover of diversity (i.e.: beta diversity). Overall gamma diversity may be lowered because species are going extinct because of other causes, but even some of the most insidious invaders (e.g.: Dutch elm disease, emerald ash borer, chestnut blight in North America) have not caused their host species to become extinct. Extirpation, population decline, and homogenization of regional biodiversity are much more common. Human activities have frequently been the cause of invasive species circumventing their barriers, by introducing them for food and other purposes. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range.

What invaders are causing changes along the North American Atlantic coast?
What is the answer?
ANS: lion fish

QUES: Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?] and has conducted several research studies in order to find methods of combating fatigue in pilots.
What can the lack of regular sleep patterns cause?

ANS: fatigue

Prior to the one-drop rule, different states had different laws regarding color. More importantly, social acceptance often played a bigger role in how a person was perceived and how identity was construed than any law. In frontier areas, there were fewer questions about origins. The community looked at how people performed, whether they served in the militia and voted, which were the responsibilities and signs of free citizens. When questions about racial identity arose because of inheritance issues, for instance, litigation outcomes often were based on how people were accepted by neighbors.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what areas were there the most questions about origins?
Ah, so.. unanswerable

Question: When performing lossy audio encoding, such as creating an MP3 file, there is a trade-off between the amount of space used and the sound quality of the result. Typically, the creator is allowed to set a bit rate, which specifies how many kilobits the file may use per second of audio. The higher the bit rate, the larger the compressed file will be, and, generally, the closer it will sound to the original file.
Try to answer this question if possible: What would an example of lossy audio encoding be?
Answer: creating an MP3 file

Problem: The bombing failed to demoralise the British into surrender or significantly damage the war economy. The eight months of bombing never seriously hampered British production and the war industries continued to operate and expand. The Blitz was only authorised when the Luftwaffe had failed to meet preconditions for a 1940 launch of Operation Sea Lion, the provisionally planned German invasion of Britain. By May 1941 the threat of an invasion of Britain had passed, and Hitler's attention had turned to Operation Barbarossa in the East. In comparison to the later Allied bombing campaign against Germany, the Blitz resulted in relatively few casualties; the British bombing of Hamburg in July 1943 inflicted some 42,000 civilian deaths, about the same as the entire Blitz.
Who was the leader of the Luftwaffe?
---
Answer:
Hitler
