Input: Brain
Most organisms studied to date utilize a rewardpunishment mechanism: for instance, worms and insects can alter their behavior to seek food sources or to avoid dangers. In vertebrates, the reward-punishment system is implemented by a specific set of brain structures, at the heart of which lie the basal ganglia, a set of interconnected areas at the base of the forebrain. There is substantial evidence that the basal ganglia are the central site at which decisions are made: the basal ganglia exert a sustained inhibitory control over most of the motor systems in the brain; when this inhibition is released, a motor system is permitted to execute the action it is programmed to carry out. Rewards and punishments function by altering the relationship between the inputs that the basal ganglia receive and the decision-signals that are emitted. The reward mechanism is better understood than the punishment mechanism, because its role in drug abuse has caused it to be studied very intensively. Research has shown that the neurotransmitter dopamine plays a central role: addictive drugs such as cocaine, amphetamine, and nicotine either cause dopamine levels to rise or cause the effects of dopamine inside the brain to be enhanced.

A set of interconnected areas at the base of the forebrain is called what?
Output: basal ganglia

Input: Boston
With nearly a third of Bostonians using public transit for their commute to work, Boston has the fifth-highest rate of public transit usage in the country. Boston's subway system, the Massachusetts Bay Transportation Authority (MBTAknown as the "T") operates the oldest underground rapid transit system in the Americas, and is the fourth-busiest rapid transit system in the country, with 65.5 miles (105 km) of track on four lines. The MBTA also operates busy bus and commuter rail networks, and water shuttles.

What is the name of Bostons subway system?
Output: MBTA

Input: Affirmative action in the United States
In the beginning, racial classifications that identified race were inherently suspect and subject to strict scrutiny. These classifications would only be upheld if necessary to promote a compelling governmental interest. Later the U.S. Supreme Court decided that racial classifications that benefited underrepresented minorities were to only be upheld if necessary and promoted a compelling governmental purpose. (See Richmond v. J.A. Croson Co.) There is no clear guidance about when government action is not "compelling", and such rulings are rare.

What was the only situation in which a racial classification could be considered acceptable?
Output: necessary to promote a compelling governmental interest

Input: Josip Broz Tito
In the years after Tito's death up to nowadays, some people have disputed his identity. Tito's personal doctor, Aleksandar Matunovic, wrote a book about Tito in which he also questioned his true origin, noting that Tito's habits and lifestyle could only mean that he was from an aristocratic family. Serbian journalist Vladan Dinic (born 1949), in Tito nije tito, includes several possible alternate identities of Tito.

Who wrote a book about Tito questioning his true origin?
Output:
Aleksandar Matunovic
