Definition: 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".

Positive Example 1 -
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?
Output: True

Positive Example 2 -
Input: Motor systems are areas of the brain that are directly or indirectly involved in producing body movements, that is, in activating muscles. Except for the muscles that control the eye, which are driven by nuclei in the midbrain, all the voluntary muscles in the body are directly innervated by motor neurons in the spinal cord and hindbrain. Spinal motor neurons are controlled both by neural circuits intrinsic to the spinal cord, and by inputs that descend from the brain. The intrinsic spinal circuits implement many reflex responses, and contain pattern generators for rhythmic movements such as walking or swimming. The descending connections from the brain allow for more sophisticated control. Question: What is isolated from the bloodstream by the blood-brain barrier?
Output: False

Negative Example 1 -
Input: NASCAR (headquartered in Daytona Beach) begins all three of its major auto racing series in Florida at Daytona International Speedway in February, featuring the Daytona 500, and ends all three Series in November at Homestead-Miami Speedway. Daytona also has the Coke Zero 400 NASCAR race weekend around Independence Day in July. The 24 Hours of Daytona is one of the world's most prestigious endurance auto races. The Grand Prix of St. Petersburg and Grand Prix of Miami have held IndyCar races as well. Question: What is the starting time of NASCAR's big events?
Output: False

Negative Example 2 -
Input: As of 2010, those of African ancestry accounted for 16.0% of Florida's population, which includes African Americans. Out of the 16.0%, 4.0% (741,879) were West Indian or Afro-Caribbean American. During the early 1900s, black people made up nearly half of the state's population. In response to segregation, disfranchisement and agricultural depression, many African Americans migrated from Florida to northern cities in the Great Migration, in waves from 1910 to 1940, and again starting in the later 1940s. They moved for jobs, better education for their children and the chance to vote and participate in society. By 1960 the proportion of African Americans in the state had declined to 18%. Conversely large numbers of northern whites moved to the state.[citation needed] Today, large concentrations of black residents can be found in northern and central Florida. Aside from blacks descended from African slaves brought to the US south, there are also large numbers of blacks of West Indian, recent African, and Afro-Latino immigrant origins, especially in the Miami/South Florida area. In 2010, Florida had the highest percentage of West Indians in the United States, with 2.0% (378,926) from Haitian ancestry, and 1.3% (236,950) Jamaican. All other (non-Hispanic) Caribbean nations were well below 0.1% of Florida residents. Question: Which rule managed the resources of Florida better?
Output: True

Now complete the following example -
Input: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union. Question: What country pushed the boundaries for railway power delivery?
Output: 


Answer: True
