Problem: Given the question: Question: "If you wanted to install an elevator in a 50 story building, how fast could you get it to go?" Context: "Passenger elevators capacity is related to the available floor space. Generally passenger elevators are available in capacities from 500 to 2,700 kg (1,0006,000 lb) in 230 kg (500 lb) increments.[citation needed] Generally passenger elevators in buildings of eight floors or fewer are hydraulic or electric, which can reach speeds up to 1 m/s (200 ft/min) hydraulic and up to 152 m/min (500 ft/min) electric. In buildings up to ten floors, electric and gearless elevators are likely to have speeds up to 3 m/s (500 ft/min), and above ten floors speeds range 3 to 10 m/s (5002,000 ft/min).[citation needed]" Answer:

The answer is:
10 m/s

Problem: Given the question: Question: "What are more problematic jobs" Context: "Concerns have often been raised over the buying public's moral complicity in purchasing products assembled or otherwise manufactured in developing countries with child labour. However, others have raised concerns that boycotting products manufactured through child labour may force these children to turn to more dangerous or strenuous professions, such as prostitution or agriculture. For example, a UNICEF study found that after the Child Labour Deterrence Act was introduced in the US, an estimated 50,000 children were dismissed from their garment industry jobs in Bangladesh, leaving many to resort to jobs such as "stone-crushing, street hustling, and prostitution", jobs that are "more hazardous and exploitative than garment production". The study suggests that boycotts are "blunt instruments with long-term consequences, that can actually harm rather than help the children involved."" Answer:
++++++++++++++++++++++++++++++++
The answer is:
prostitution or agriculture

Problem: Given the question: Question: "what is the first word in the second paragraph?" Context: "A CD is read by focusing a 780 nm wavelength (near infrared) semiconductor laser housed within the CD player, through the bottom of the polycarbonate layer. The change in height between pits and lands results in a difference in the way the light is reflected. By measuring the intensity change with a photodiode, the data can be read from the disc. In order to accommodate the spiral pattern of data, the semiconductor laser is placed on a swing arm within the disc tray of any CD player. This swing arm allows the laser to read information from the centre to the edge of a disc, without having to interrupt the spinning of the disc itself." Answer:
++++++++++++++++++++++++++++++++
The answer is:
change
