Input: Vacuum
The SI unit of pressure is the pascal (symbol Pa), but vacuum is often measured in torrs, named for Torricelli, an early Italian physicist (16081647). A torr is equal to the displacement of a millimeter of mercury (mmHg) in a manometer with 1 torr equaling 133.3223684 pascals above absolute zero pressure. Vacuum is often also measured on the barometric scale or as a percentage of atmospheric pressure in bars or atmospheres. Low vacuum is often measured in millimeters of mercury (mmHg) or pascals (Pa) below standard atmospheric pressure. "Below atmospheric" means that the absolute pressure is equal to the current atmospheric pressure.

What is a torr equal to?
Output: displacement of a millimeter of mercury

Input: Professional wrestling
At times a character may "turn", altering their face/heel alignment. This may be an abrupt, surprising event, or it may slowly build up over time. It almost always is accomplished with a markable change in behavior on the part of the character. Some turns become defining points in a wrestler's career, as was the case when Hulk Hogan turned heel after being a top face for over a decade. Others may have no noticeable effect on the character's status. If a character repeatedly switches between being a face and heel, this lessens the effect of such turns, and may result in apathy from the audience. Vince McMahon is a good example of having more heel and face turns than anyone in WWE history.

Who has the most turns in the WWE?
Output: Vince McMahon

Input: Elevator
Some types of residential elevators do not use a traditional elevator shaft, machine room, and elevator hoistway. This allows an elevator to be installed where a traditional elevator may not fit, and simplifies installation. The ASME board first approved machine-room-less systems in a revision of the ASME A17.1 in 2007. Machine-room-less elevators have been available commercially since the mid 1990s, however cost and overall size prevented their adoption to the residential elevator market until around 2010.

What types of elevators occassionaly do not use a traditional elevator shaft, machine room or hoistway?
Output: residential

Input: Multiracial American
In 1790, the first federal population census was taken in the United States. Enumerators were instructed to classify free residents as white or "other." Only the heads of households were identified by name in the federal census until 1850. Native Americans were included among "Other;" in later censuses, they were included as "Free people of color" if they were not living on Indian reservations. Slaves were counted separately from free persons in all the censuses until the Civil War and end of slavery. In later censuses, people of African descent were classified by appearance as mulatto (which recognized visible European ancestry in addition to African) or black.

Were all residents counted together or separately?
Output:
Slaves were counted separately from free persons
