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: It is admitted that the doctrine as defined by Pius IX was not explicitly mooted before the 12th century. It is also agreed that "no direct or categorical and stringent proof of the dogma can be brought forward from Scripture". But it is claimed that the doctrine is implicitly contained in the teaching of the Fathers. Their expressions on the subject of the sinlessness of Mary are, it is pointed out, so ample and so absolute that they must be taken to include original sin as well as actual. Thus in the first five centuries such epithets as "in every respect holy", "in all things unstained", "super-innocent", and "singularly holy" are applied to her; she is compared to Eve before the fall, as ancestress of a redeemed people; she is "the earth before it was accursed". The well-known words of St. Augustine (d. 430) may be cited: "As regards the mother of God," he says, "I will not allow any question whatever of sin." It is true that he is here speaking directly of actual or personal sin. But his argument is that all men are sinners; that they are so through original depravity; that this original depravity may be overcome by the grace of God, and he adds that he does not know but that Mary may have had sufficient grace to overcome sin "of every sort" (omni ex parte).
