input: Please answer the following: Extract the answer to the question from the following context. Question: What is an advantage of testing brain function in animals? Context: 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.

Please answer this: Extract the answer to the question from the following context. Question: What is the combination of old and new technology? Context: Some independent stereo manufacturers including JVC, Pioneer, Kenwood, Alpine, Sony, and Harman Kardon also have iPod-specific integration solutions. Alternative connection methods include adapter kits (that use the cassette deck or the CD changer port), audio input jacks, and FM transmitters such as the iTrip—although personal FM transmitters are illegal in some countries. Many car manufacturers have added audio input jacks as standard.

Problem: Extract the answer to the question from the following context. Question: How can you describe the source of some Estonian words? Context: Although the Estonian and Germanic languages are of very different origins, one can identify many similar words in Estonian and English, for example. This is primarily because the Estonian language has borrowed nearly one third of its vocabulary from Germanic languages, mainly from Low Saxon (Middle Low German) during the period of German rule, and High German (including standard German). The percentage of Low Saxon and High German loanwords can be estimated at 22–25 percent, with Low Saxon making up about 15 percent.[citation needed]

A: Germanic languages

Problem: Given the question: Extract the answer to the question from the following context. Question: Who were the emperors compared to? Context: With the abatement of persecution, St. Jerome acknowledged the Empire as a bulwark against evil but insisted that "imperial honours" were contrary to Christian teaching. His was an authoritative but minority voice: most Christians showed no qualms in the veneration of even "pagan" emperors. The peace of the emperors was the peace of God; as far as the Church was concerned, internal dissent and doctrinal schism were a far greater problem. The solution came from a hitherto unlikely source: as pontifex maximus Constantine I favoured the "Catholic Church of the Christians" against the Donatists because:
