Given a paragraph from a Wikipedia article about some topic, and a question related to the topic, determine whether the question is answerable from the paragraph. If the question is answerable, answer "True", otherwise, answer "False".

Let me give you an example: 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?
The answer to this example can be: True
Here is 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.

OK. solve this:
The biggest change in this year's census was in racial classification. Enumerators were instructed to no longer use the "Mulatto" classification. Instead, they were given special instructions for reporting the race of interracial persons. A person with both white and black ancestry (termed "blood") was to be recorded as "Negro," no matter the fraction of that lineage (the "one-drop rule"). A person of mixed black and American Indian ancestry was also to be recorded as "Neg" (for "Negro") unless he was considered to be "predominantly" American Indian and accepted as such within the community. A person with both White and American Indian ancestry was to be recorded as an Indian, unless his American Indian ancestry was small, and he was accepted as white within the community. In all situations in which a person had White and some other racial ancestry, he was to be reported as that other race. Persons who had minority interracial ancestry were to be reported as the race of their father. Question: What were Mexicans classified as before the U.S. agencies classified them as white?
Answer:
False
