Problem: Given the question: Extract the answer to the question from the following context. Question: What is key in universal motors? Context: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.

universal motors are often found in a range less than 1000 watts


Problem: Given the question: Extract the answer to the question from the following context. Question: What makes this dialect unique? Context: The New York area is home to a distinctive regional speech pattern called the New York dialect, alternatively known as Brooklynese or New Yorkese. It has generally been considered one of the most recognizable accents within American English. The classic version of this dialect is centered on middle and working-class people of European descent. However, the influx of non-European immigrants in recent decades has led to changes in this distinctive dialect, and the traditional form of this speech pattern is no longer as prevalent among general New Yorkers as in the past.

Problem: Given the question: Extract the answer to the question from the following context. Question: What is the current safety status of the plant? Context: The Zipingpu Hydropower Plant (simplified Chinese: 紫坪铺水库; traditional Chinese: 紫坪鋪水庫) located 20 km east of the epicenter was damaged. A recent inspection indicated that the damage was less severe than initially feared, and it remains structurally stable and safe. The Tulong reservoir upstream is in danger of collapse. About 2,000 troops have been allocated to Zipingpu, trying to release the pressure through spillway. In total, 391 dams, most of them small, were reported damaged by the quake.
