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 bloodbrain 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: After Richard's death on 6 April 1199 there were two potential claimants to the Angevin throne: John, whose claim rested on being the sole surviving son of Henry II, and young Arthur I of Brittany, who held a claim as the son of John's elder brother Geoffrey. Richard appears to have started to recognise John as his heir presumptive in the final years before his death, but the matter was not clear-cut and medieval law gave little guidance as to how the competing claims should be decided. With Norman law favouring John as the only surviving son of Henry II and Angevin law favouring Arthur as the only son of Henry's elder son, the matter rapidly became an open conflict. John was supported by the bulk of the English and Norman nobility and was crowned at Westminster, backed by his mother, Eleanor. Arthur was supported by the majority of the Breton, Maine and Anjou nobles and received the support of Philip II, who remained committed to breaking up the Angevin territories on the continent. With Arthur's army pressing up the Loire valley towards Angers and Philip's forces moving down the valley towards Tours, John's continental empire was in danger of being cut in two. Question: The one whose claim rested on being the sole surviving son of Henry II wasn't supported by what nobles?
Solution:
True
