The problem: Answer a question about this article:
The Gurkhas, a martial tribe, came to power in Nepal in the year 1768. They consolidated their military power and began to expand their territory. Gradually, the Gorkhas annexed Sirmour and Shimla. With the leadership of Amar Singh Thapa, Gorkhas laid siege to Kangra. They managed to defeat Sansar Chand Katoch, the ruler of Kangra, in 1806 with the help of many provincial chiefs. However, Gurkhas could not capture Kangra fort which came under Maharaja Ranjeet Singh in 1809. After the defeat, the Gurkhas began to expand towards the south of the state. However, Raja Ram Singh, Raja of Siba State managed to capture the fort of Siba from the remnants of Lahore Darbar in Samvat 1846, during the First Anglo-Sikh War. They came into direct conflict with the British along the tarai belt after which the British expelled them from the provinces of the Satluj. The British gradually emerged as the paramount power. In the revolt of 1857, or first Indian war of independence, arising from a number of grievances against the British, the people of the hill states were not as politically active as were those in other parts of the country. They and their rulers, with the exception of Bushahr, remained more or less inactive. Some, including the rulers of Chamba, Bilaspur, Bhagal and Dhami, rendered help to the British government during the revolt.
When did the Gurkhas come into power?
****
The answer: 1768

Problem: Please answer a question about the following article about Arnold Schwarzenegger:
Schwarzenegger's endorsement in the Republican primary of the 2008 U.S. presidential election was highly sought; despite being good friends with candidates Rudy Giuliani and Senator John McCain, Schwarzenegger remained neutral throughout 2007 and early 2008. Giuliani dropped out of the presidential race on January 30, 2008, largely because of a poor showing in Florida, and endorsed McCain. Later that night, Schwarzenegger was in the audience at a Republican debate at the Ronald Reagan Presidential Library in California. The following day, he endorsed McCain, joking, "It's Rudy's fault!" (in reference to his friendships with both candidates and that he could not make up his mind). Schwarzenegger's endorsement was thought to be a boost for Senator McCain's campaign; both spoke about their concerns for the environment and economy.
Who did Schwarzenegger finally endorse in the 2008 Republican primary?
A: John McCain

The London Underground in England is one of the few networks that uses a four-rail system. The additional rail carries the electrical return that, on third rail and overhead networks, is provided by the running rails. On the London Underground, a top-contact third rail is beside the track, energized at +420v DC, and a top-contact fourth rail is located centrally between the running rails at 210v DC, which combine to provide a traction voltage of 630v DC. London Underground is now upgrading its fourth rail system to 750v DC with a positive conductor rail energised to +500v DC and a negative conductor rail energised to -250v DC. However, many older sections in tunnels are still energised to 630v DC. The same system was used for Milan's earliest underground line, Milan Metro's line 1, whose more recent lines use an overhead catenary or a third rail.

What is the voltage of the return rail?
Answer: 210v DC

Problem: The cocoa industry was accused of profiting from child slavery and trafficking. The European Cocoa Association dismissed these accusations as "false and excessive" and the industry said the reports were not representative of all areas. Later the industry acknowledged the working conditions for children were unsatisfactory and children's rights were sometimes violated and acknowledged the claims could not be ignored. In a BBC interview, the ambassador for Ivory Coast to the United Kingdom called these reports of widespread use of slave child labour by 700,000 cocoa farmers as absurd and inaccurate.
What are the figures for cocoa farmers using child labour?
The answer is the following: 700,000

Notably, the most broadly influential innovation of 20th-century American tort law was the rule of strict liability for defective products, which originated with judicial glosses on the law of warranty. In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products. The American Law Institute subsequently adopted a slightly different version of the Greenman rule in Section 402A of the Restatement (Second) of Torts, which was published in 1964 and was very influential throughout the United States. Outside the U.S., the rule was adopted by the European Economic Community in the Product Liability Directive of July 1985 by Australia in July 1992 and by Japan in June 1994.
What case was fundamental in the fight to change warranty laws?
Greenman v. Yuba Power Products

Here is a question about this article: The climate in Southeast Asia is mainly tropicalhot and humid all year round with plentiful rainfall. Northern Vietnam and the Myanmar Himalayas are the only regions in Southeast Asia that feature a subtropical climate, which has a cold winter with snow. The majority of Southeast Asia has a wet and dry season caused by seasonal shift in winds or monsoon. The tropical rain belt causes additional rainfall during the monsoon season. The rain forest is the second largest on earth (with the Amazon being the largest). An exception to this type of climate and vegetation is the mountain areas in the northern region, where high altitudes lead to milder temperatures and drier landscape. Other parts fall out of this climate because they are desert like.
What is the answer to this question: Which region has the 2nd largest rain-forest in the world?
****
So...
Southeast Asia
