The problem: Answer a question about this article:
Since annelids are soft-bodied, their fossils are rare – mostly jaws and the mineralized tubes that some of the species secreted. Although some late Ediacaran fossils may represent annelids, the oldest known fossil that is identified with confidence comes from about 518 million years ago in the early Cambrian period. Fossils of most modern mobile polychaete groups appeared by the end of the Carboniferous, about 299 million years ago. Palaeontologists disagree about whether some body fossils from the mid Ordovician, about 472 to 461 million years ago, are the remains of oligochaetes, and the earliest indisputable fossils of the group appear in the Tertiary period, which began 65 million years ago.
How old is the earliest annelid fossil?
****
The answer: 518 million years ago


Problem: Please answer a question about the following article about Dwight D. Eisenhower:
The Germans launched a surprise counter offensive, in the Battle of the Bulge in December 1944, which the Allies turned back in early 1945 after Eisenhower repositioned his armies and improved weather allowed the Air Force to engage. German defenses continued to deteriorate on both the eastern front with the Soviets and the western front with the Allies. The British wanted Berlin, but Eisenhower decided it would be a military mistake for him to attack Berlin, and said orders to that effect would have to be explicit. The British backed down, but then wanted Eisenhower to move into Czechoslovakia for political reasons. Washington refused to support Churchill's plan to use Eisenhower's army for political maneuvers against Moscow. The actual division of Germany followed the lines that Roosevelt, Churchill and Stalin had previously agreed upon. The Soviet Red Army captured Berlin in a very large-scale bloody battle, and the Germans finally surrendered on May 7, 1945.
When did the Battle of the Bulge begin?
A: December 1944

However, as stealth technology grows, so does anti-stealth technology. Multiple transmitter radars such as those from bistatic radars and low-frequency radars are said to have the capabilities to detect stealth aircraft. Advanced forms of thermographic cameras such as those that incorporate QWIPs would be able to optically see a Stealth aircraft regardless of the aircraft's RCS. In addition, Side looking radars, High-powered optical satellites, and sky-scanning, high-aperture, high sensitivity radars such as radio telescopes, would all be able to narrow down the location of a stealth aircraft under certain parameters. The newest SAM's have a claimed ability to be able to detect and engage stealth targets, with the most notable being the S-400, which is claimed to be able to detect a target with a 0.05 meter squared RCS from 90 km away.

How far away can the S-400 detect a target?
Answer: 90 km away


Problem: Comcast is sometimes described as a family business. Brian L. Roberts, Chairman, President, and CEO of Comcast, is son of co-founder Ralph Roberts. Roberts owns or controls just over 1% of all Comcast shares but all of the Class B supervoting shares, which gives him an "undilutable 33% voting power over the company". Legal expert Susan P. Crawford has said this gives him "effective control over its [Comcast's] every step". In 2010, he was one of the highest-paid executives in the United States, with total compensation of about $31 million.
Who is the current head of Comcast?
The answer is the following: Brian L. Roberts


The rise of port cities saw the clustering of populations caused by the development of steamships and railroads. Urbanization increased from 1700 to 1922, with towns and cities growing. Improvements in health and sanitation made them more attractive to live and work in. Port cities like Salonica, in Greece, saw its population rise from 55,000 in 1800 to 160,000 in 1912 and İzmir which had a population of 150,000 in 1800 grew to 300,000 by 1914. Some regions conversely had population falls – Belgrade saw its population drop from 25,000 to 8,000 mainly due to political strife.
The rise of ports caused what in populations?
the clustering of populations


Here is a question about this article: 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.
What is the answer to this question: What is Shell's primary business?
****
So...
the management of a vertically integrated oil company
