Another approach to brain function is to examine the consequences of damage to specific brain areas. Even though it is protected by the skull and meninges, surrounded by cerebrospinal fluid, and isolated from the bloodstream by the blood–brain barrier, the delicate nature of the brain makes it vulnerable to numerous diseases and several types of damage. In humans, the effects of strokes and other types of brain damage have been a key source of information about brain function. Because there is no ability to experimentally control the nature of the damage, however, this information is often difficult to interpret. In animal studies, most commonly involving rats, it is possible to use electrodes or locally injected chemicals to produce precise patterns of damage and then examine the consequences for behavior. Question: What is surrounded by cerebrospinal fluid?
Solution: True
Why? The paragraph comes from the wikipedia page on the brain. The answer to the question is the brain which can be found in the paragraph.

New input: Henry the Young King fought a short war with his brother Richard in 1183 over the status of England, Normandy and Aquitaine. Henry II moved in support of Richard, and Henry the Young King died from dysentery at the end of the campaign. With his primary heir dead, Henry rearranged the plans for the succession: Richard was to be made King of England, albeit without any actual power until the death of his father; Geoffrey would retain Brittany; and John would now become the Duke of Aquitaine in place of Richard. Richard refused to give up Aquitaine; Henry II was furious and ordered John, with help from Geoffrey, to march south and retake the duchy by force. The two attacked the capital of Poitiers, and Richard responded by attacking Brittany. The war ended in stalemate and a tense family reconciliation in England at the end of 1184. Question: How did the war end?
Solution:
True
