Input: Royal Dutch Shell
Shell's primary business is the management of a vertically integrated oil company. The development of technical and commercial expertise in all stages of this vertical integration, from the initial search for oil (exploration) through its harvesting (production), transportation, refining and finally trading and marketing established the core competencies on which the company was founded. Similar competencies were required for natural gas, which has become one of the most important businesses in which Shell is involved, and which contributes a significant proportion of the company's profits. While the vertically integrated business model provided significant economies of scale and barriers to entry, each business now seeks to be a self-supporting unit without subsidies from other parts of the company.

The development of what two types of exptertise established the core competencies on which the company was founded?
Output: technical and commercial


Input: Article: Kanye West began his early production career in the mid-1990s, making beats primarily for burgeoning local artists, eventually developing a style that involved speeding up vocal samples from classic soul records. His first official production credits came at the age of nineteen when he produced eight tracks on Down to Earth, the 1996 debut album of a Chicago rapper named Grav. For a time, West acted as a ghost producer for Deric "D-Dot" Angelettie. Because of his association with D-Dot, West wasn't able to release a solo album, so he formed and became a member and producer of the Go-Getters, a late-1990s Chicago rap group composed of him, GLC, Timmy G, Really Doe, and Arrowstar. His group was managed by John "Monopoly" Johnson, Don Crowley, and Happy Lewis under the management firm Hustle Period. After attending a series of promotional photo shoots and making some radio appearances, The Go-Getters released their first and only studio album World Record Holders in 1999. The album featured other Chicago-based rappers such as Rhymefest, Mikkey Halsted, Miss Criss, and Shayla G. Meanwhile, the production was handled by West, Arrowstar, Boogz, and Brian "All Day" Miller.

Now answer this question: Who were the beats Kanye made in the 90's originally intended for?

Output: local artists

The problem: Answer a question about this article:
In the early 1880s, Kanehiro Takaki observed that Japanese sailors (whose diets consisted almost entirely of white rice) developed beriberi (or endemic neuritis, a disease causing heart problems and paralysis), but British sailors and Japanese naval officers did not. Adding various types of vegetables and meats to the diets of Japanese sailors prevented the disease, (not because of the increased protein as Takaki supposed but because it introduced a few parts per million of thiamine to the diet, later understood as a cure).
Who made the observation that the Japanese sailor's diet was the cause for them developing beriberi?
****
The answer: Kanehiro Takaki


The problem: Answer a question about this article:
By the end of 2011, total renewable power capacity worldwide exceeded 1,360 GW, up 8%. Renewables producing electricity accounted for almost half of the 208 GW of capacity added globally during 2011. Wind and solar photovoltaics (PV) accounted for almost 40% and 30% . Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass.
Renewables contributed what percentage to our energy consumption?
****
The answer:
19 percent
