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: The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war. Question: Whose tantrum was ineffectual?
Solution:
True
