Input: The Bronx
The Bronx underwent rapid urban growth after World War I. Extensions of the New York City Subway contributed to the increase in population as thousands of immigrants came to the Bronx, resulting in a major boom in residential construction. Among these groups, many Irish Americans, Italian Americans and especially Jewish Americans settled here. In addition, French, German, Polish and other immigrants moved into the borough. The Jewish population also increased notably during this time. In 1937, according to Jewish organizations, 592,185 Jews lived in The Bronx (43.9% of the borough's population), while only 54,000 Jews lived in the borough in 2011. Many synagogues still stand in the Bronx, but most have been converted to other uses.

What led to the Bronx's population growth?
Output: Extensions of the New York City Subway

Input: Capacitor
In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.

In what what unit is the capacitance reported for capacitors used in power factor correction?
Output: reactive power in volt-amperes reactive (var)

Input: Prime minister
The prime minister is often, but not always, a member of parliament[clarification needed] and is expected with other ministers to ensure the passage of bills through the legislature. In some monarchies the monarch may also exercise executive powers (known as the royal prerogative) that are constitutionally vested in the crown and may be exercised without the approval of parliament.

What is it called when a monarch has a share of executive powers?
Output: royal prerogative

Input: Neptune
On 11 July 2011, Neptune completed its first full barycentric orbit since its discovery in 1846, although it did not appear at its exact discovery position in the sky, because Earth was in a different location in its 365.26-day orbit. Because of the motion of the Sun in relation to the barycentre of the Solar System, on 11 July Neptune was also not at its exact discovery position in relation to the Sun; if the more common heliocentric coordinate system is used, the discovery longitude was reached on 12 July 2011.

Why didn't Neptune appear to be in it's exact discover position? 
Output:
Earth was in a different location
