Input: IBM
IBM has constantly evolved since its inception. Over the past decade, it has steadily shifted its business mix by exiting commoditizing markets such as PCs, hard disk drives and DRAMs and focusing on higher-value, more profitable markets such as business intelligence, data analytics, business continuity, security, cloud computing, virtualization and green solutions, resulting in a higher quality revenue stream and higher profit margins. IBM's operating margin expanded from 16.8% in 2004 to 24.3% in 2013, and net profit margins expanded from 9.0% in 2004 to 16.5% in 2013.

What were the net profit margins of IBM in 2004?
Output: 9.0%

Input: Article: In The Use of Knowledge in Society (1945), Hayek argued that the price mechanism serves to share and synchronise local and personal knowledge, allowing society's members to achieve diverse, complicated ends through a principle of spontaneous self-organization. He contrasted the use of the price mechanism with central planning, arguing that the former allows for more rapid adaptation to changes in particular circumstances of time and place. Thus, he set the stage for Oliver Williamson's later contrast between markets and hierarchies as alternative co-ordination mechanisms for economic transactions. He used the term catallaxy to describe a "self-organizing system of voluntary co-operation". Hayek's research into this argument was specifically cited by the Nobel Committee in its press release awarding Hayek the Nobel prize.

Now answer this question: The arguments presented in The Use of Knowledge in Society created an starting point for who?

Output: Oliver Williamson

Article: On 22 May 2015, Sun reporter Anthony France was found guilty of aiding and abetting misconduct in a public office between 2008 and 2011. France's trial followed the London Metropolitan Police's Operation Elveden, an ongoing investigation into alleged payments to police and officials in exchange for information. He had paid a total of more than 22,000 to PC Timothy Edwards, an anti-terrorism police officer based at Heathrow Airport. The police officer had already pleaded guilty to misconduct in a public office and given a two-year gaol sentence in 2014, but the jury in France's trial was not informed of this. Following the passing of the guilty verdict, the officer leading Operation Elveden, Detective Chief Superintendent Gordon Briggs said France and Edwards had been in a "long-term, corrupt relationship".

Question: How much did Anthony France pay to a police officer?
Ans: more than 22,000

Here is a question about this article: High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens. LED power densities up to 300 W/cm2 have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a heat sink to allow for heat dissipation. If the heat from a HP-LED is not removed, the device will fail in seconds. One HP-LED can often replace an incandescent bulb in a flashlight, or be set in an array to form a powerful LED lamp.
What is the answer to this question: Up to how many densities have been achieved with LED power?
****
So... 300 W/cm2

The problem: Answer a question about this article:
In Canada, "college" generally refers to a two-year, non-degree-granting institution, while "university" connotes a four-year, degree-granting institution. Universities may be sub-classified (as in the Macleans rankings) into large research universities with many PhD granting programs and medical schools (for example, McGill University); "comprehensive" universities that have some PhDs but aren't geared toward research (such as Waterloo); and smaller, primarily undergraduate universities (such as St. Francis Xavier).
A college teaches students for how many years in Canada?
****
The answer: two

The problem: Answer a question about this article:
Historically, AC motors were used for single or double speed elevator machines on the grounds of cost and lower usage applications where car speed and passenger comfort were less of an issue, but for higher speed, larger capacity elevators, the need for infinitely variable speed control over the traction machine becomes an issue. Therefore, DC machines powered by an AC/DC motor generator were the preferred solution. The MG set also typically powered the relay controller of the elevator, which has the added advantage of electrically isolating the elevators from the rest of a building's electrical system, thus eliminating the transient power spikes in the building's electrical supply caused by the motors starting and stopping (causing lighting to dim every time the elevators are used for example), as well as interference to other electrical equipment caused by the arcing of the relay contactors in the control system.
What is a known advantage of the MG set?
****
The answer:
electrically isolating the elevators from the rest of a building's electrical system
