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".

Example input: 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?
Example output: True
Example explanation: 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.
Q: In the Late Empire and Middle Ages Vergilius was spelled Virgilius. Two explanations are commonly given for this alteration. One deduces a false etymology associated with the word virgo ("maiden" in Latin) due to Virgil's excessive, "maiden"-like modesty. Alternatively, some argue that Vergilius was altered to Virgilius by analogy with the Latin virga ("wand") due to the magical or prophetic powers attributed to Virgil in the Middle Ages (this explanation is found in only a handful of manuscripts, however, and was probably not widespread). In Norman schools (following the French practice), the habit was to anglicize Latin names by dropping their Latin endings, hence Virgil. In the 19th century, some German-trained classicists in the United States suggested modification to Vergil, as it is closer to his original name, and is also the traditional German spelling.[citation needed] Modern usage permits both, though the Oxford guide to style recommends Vergilius to avoid confusion with the 8th-century grammarian Virgilius Maro Grammaticus. Some post-Renaissance writers liked to affect the sobriquet "The Swan of Mantua".[citation needed] Question: what is the second era mentioned?
A:
True
