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:
At the time, there were many varying opinions about Christian doctrine, and no centralized way of enforcing orthodoxy. Constantine called all the Christian bishops throughout the Roman Empire to a meeting, and some 318 bishops (very few from the Western Empire) attended the First Council of Nicaea. The purpose of this meeting was to define Christian orthodoxy and clearly differentiate it from Christian heresies. The meeting reached consensus on the Nicene Creed and other statements. Later, Philostorgius criticized Christians who offered sacrifice at statues of the divus Constantine. Constantine nevertheless took great pains to assuage traditionalist and Christian anxieties. Question: Which of the following is not a type of Christian philosophy: orthodoxy, heresies or meeting?
Answer:
True
