Input: Read this: In February 2010 Shell and Cosan formed a 50:50 joint-venture, Raízen, comprising all of Cosan's Brazilian ethanol, energy generation, fuel distribution and sugar activities, and all of Shell's Brazilian retail fuel and aviation distribution businesses. In March 2010, Shell announced the sale of some of its assets, including its liquid petroleum gas (LPG) business, to meet the cost of a planned $28bn capital spending programme. Shell invited buyers to submit indicative bids, due by 22 March, with a plan to raise $2–3bn from the sale. In June 2010, Royal Dutch Shell agreed to acquire all the business of East Resources for a cash consideration of $4.7 billion. The transaction included East Resources' tight gas fields.
Question: In what year did Shell and Cosan form a 50:50 joint venture?

Output: 2010


QUES: In November 2014, Sony Pictures Entertainment was targeted by hackers who released details of confidential e-mails between Sony executives regarding several high-profile film projects. Included within these were several memos relating to the production of Spectre, claiming that the film was over budget, detailing early drafts of the script written by John Logan, and expressing Sony's frustration with the project. Eon Productions later issued a statement confirming the leak of what they called "an early version of the screenplay".

What company confirmed that an early version of the Spectre script had been leaked?
What is the answer?
ANS: Eon Productions


QUES: Intermittent warfare lasting from July 23, 1670 until July 1695, plus the typhoons of 1671 and 1693, and in particular the smallpox epidemic of 1688, reduced the Chamorro population from 50,000 to 10,000 to less than 5,000.:86 Precipitated by the death of Quipuha, and the murder of Father San Vitores and Pedro Calungsod by local rebel chief Matapang, tensions led to a number of conflicts. Captain Juan de Santiago started a campaign to pacify the island, which was continued by the successive commanders of the Spanish forces.:68–74
What was the name of the person who started the campaign to pacify the area?

ANS: Juan de Santiago


Network effects are a large factor with electrification. When converting lines to electric, the connections with other lines must be considered. Some electrifications have subsequently been removed because of the through traffic to non-electrified lines. If through traffic is to have any benefit, time consuming engine switches must occur to make such connections or expensive dual mode engines must be used. This is mostly an issue for long distance trips, but many lines come to be dominated by through traffic from long-haul freight trains (usually running coal, ore, or containers to or from ports). In theory, these trains could enjoy dramatic savings through electrification, but it can be too costly to extend electrification to isolated areas, and unless an entire network is electrified, companies often find that they need to continue use of diesel trains even if sections are electrified. The increasing demand for container traffic which is more efficient when utilizing the double-stack car also has network effect issues with existing electrifications due to insufficient clearance of overhead electrical lines for these trains, but electrification can be built or modified to have sufficient clearance, at additional cost.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What can be a drawback of electrification of long distance freight trains?
Ah, so.. electrification to isolated areas


Question: C trigraphs were created to solve this problem for ANSI C, although their late introduction and inconsistent implementation in compilers limited their use. Many programmers kept their computers on US-ASCII, so plain-text in Swedish, German etc. (for example, in e-mail or Usenet) contained "{, }" and similar variants in the middle of words, something those programmers got used to. For example, a Swedish programmer mailing another programmer asking if they should go for lunch, could get "N{ jag har sm|rg}sar." as the answer, which should be "Nä jag har smörgåsar." meaning "No I've got sandwiches."
Try to answer this question if possible: What was created to solve the problem for ANSI C?
Answer: C trigraphs


Input: Read this: Crevasses can form in several different ways. Transverse crevasses are transverse to flow and form where steeper slopes cause a glacier to accelerate. Longitudinal crevasses form semi-parallel to flow where a glacier expands laterally. Marginal crevasses form from the edge of the glacier, due to the reduction in speed caused by friction of the valley walls. Marginal crevasses are usually largely transverse to flow. Moving glacier ice can sometimes separate from stagnant ice above, forming a bergschrund. Bergschrunds resemble crevasses but are singular features at a glacier's margins.
Question: Why do marginal crevasses form on the edge of a glacier?

Output:
reduction in speed caused by friction of the valley walls
