The problem: Answer a question about this article:
The low mechanical complexity of hydraulic elevators in comparison to traction elevators makes them ideal for low rise, low traffic installations. They are less energy efficient as the pump works against gravity to push the car and its passengers upwards; this energy is lost when the car descends on its own weight. The high current draw of the pump when starting up also places higher demands on a building’s electrical system. There are also environmental concerns should the lifting cylinder leak fluid into the ground.
What else contributes to a higher demand from the electrical system?
****
The answer: The high current draw of the pump when starting up

Question: Read this and answer the question

Paris' manufacturing is mostly focused in its suburbs, and the city itself has only around 75,000 manufacturing workers, most of which are in the textile, clothing, leather goods and shoe trades. Paris region manufacturing specialises in transportation, mainly automobiles, aircraft and trains, but this is in a sharp decline: Paris proper manufacturing jobs dropped by 64 percent between 1990 and 2010, and the Paris region lost 48 percent during the same period. Most of this is due to companies relocating outside the Paris region. The Paris region's 800 aerospace companies employed 100,000. Four hundred automobile industry companies employ another 100,000 workers: many of these are centred in the Yvelines department around the Renault and PSA-Citroen plants (this department alone employs 33,000), but the industry as a whole suffered a major loss with the 2014 closing of a major Aulnay-sous-Bois Citroen assembly plant.

How many people does the Paris regions aerospace companies employ?
Answer: 100,000
