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: Hong Kong: The event was held in Hong Kong on May 2. In the ceremony held at the Hong Kong Cultural Centre in Tsim Sha Tsui, Chief Executive Donald Tsang handed the torch to the first torchbearer, Olympic medalist Lee Lai Shan. The torch relay then traveled through Nathan Road, Lantau Link, Sha Tin (crossed Shing Mun River via a dragon boat, which had been never used before in the history of Olympic torch relays), Victoria Harbour (crossed by Tin Hau, a VIP vessel managed by the Marine Department) before ending in Golden Bauhinia Square in Wan Chai. A total of 120 torchbearers were selected to participate in the event consisting of celebrities, athletes and pro-Beijing camp politicians. No politicians from the pro-democracy camp were selected as torchbearers. One torchbearer could not participate due to flight delay. It was estimated that more than 200,000 spectators came out and watched the relay. Many enthusiastic supporters wore red shirts and waved large Chinese flags. According to Hong Kong Chief Secretary for Administration Henry Tang, 3,000 police were deployed to ensure order. Question: Which were there more of at the Olympic torch relay, spectators or police?
