[EX Q]: Question: Which of the rivers that Crevaux encountered was the longest? Passage:The interior of French Guiana was virtually unknown and Crevaux decided to lead an exploration into its depths. On July 8, 1877 Crevaux traveled up the Maroni River where he encountered the Galibi and the Bonis. He left the Maroni to follow a tributary, the Itany River, along the way he visited the Roucouyenne and then followed an Emerillon trail over the spine of the Tumuk Humak Mountains. He descended the other side of the mountains to the Jari River, a tributary of the Amazon. By December 1877 he had reached the Brazilian city of Belém. He was nearly naked and had lost or used most of his possessions, and was believed by the Brazilian inhabitants to be an escaped French prisoner and was refused any help. He was eventually aided by a fellow Frenchman who bought him passage on a ship back to France. Upon returning to France, Crevaux gave an account of his journey to the Société de Géographie and was made a "Knight" of the Légion d'honneur.

[EX Q]: Question: How long had the prime minister served in that position at the time of the announcement of the anti-piracy measures? Passage:On 28 January 2009, Japan announced its intention of sending a naval task force to join international efforts to stop piracy off the coast of Somalia. The deployment would be highly unusual, as Japan's non-aggressive constitution means Japanese military forces can only be used for defensive purposes. The issue has been controversial in Japan, although the ruling party maintains this should be seen as fighting crime on the high seas, rather than a "military" operation. The process of the Prime Minister of Japan, Taro Aso, giving his approval is expected to take approximately one month. However, the Japanese Maritime Self-Defense Force (JMSDF) and the Japanese government face legal problems on how to handle attacks by pirates against ships that either have Japanese personnel, cargo or are under foreign control instead of being under Japanese control as current Article 9 regulations would hamper their actions when deployed to Somalia. It was reported on 4 February 2009, that the JMSDF was sending a fact-finding mission led by Gen Nakatani to the region prior to the deployment of the Murasame-class destroyer Samidare and the Takanami-class destroyer Sazanami to the coast of Somalia with a 13-man team composed of Japanese Ministry of Defense personnel, with members coming from the Ministry of Foreign Affairs and the JMSDF to visit Yemen, Djibouti, Oman, and Bahrain from 8 to 20 February. Both JMSDF vessels are units of the 8th Escort Division of the 4th Escort Flotilla based in Kure, Hiroshima Prefecture. The JMSDF's special forces unit, the Special Boarding Unit is also scheduled to potentially deploy to Somalia. The SBU has been deployed alongside the two destroyers to Somalia on 14 March 2009. According to JMSDF officials, the deployment would "regain the trust of the shipping industry, which was lost during the war." The JMSDF task force would be deployed off the coast of Somalia for 4 months. In its first mission, the Sazanami was able to ward off pirates attempting to hijack a Singaporean cargo ship. In addition, JMSDF P-3Cs are to be deployed in June from Djibouti to conduct surveillance on the Somali coast. The House of Representatives of Japan has passed an anti-piracy bill, calling for the JMSDF to protect non-Japanese ships and nationals, though there are some concerns that the pro-opposition House of Councillors may reject it. The Diet of Japan has passed an anti-piracy law that called for JMSDF forces to protect all foreign ships traveling off the coast of Somalia aside from protecting Japanese-owned/manned ships despite a veto from the House of Councillors, which the House of Representatives has overturned. In 2009, the Murasame-class destroyer Harusame and the Asagiri-class destroyer Amagiri left port from Yokusuka to replace the two destroyers that had been dispatched earlier in March 2009. Under current arrangements, Japan Coast Guard officers would be responsible for arresting pirates since SDF forces are not allowed to have powers of arrest.

[EX Q]: Question: Which founder of the railroad which eventually became the Virginian Railway was born first? Passage:Early in the 20th century, William Nelson Page, a civil engineer and coal mining manager, joined forces with a silent partner, industrialist financier Henry Huttleston Rogers (a principal of Standard Oil and one of the wealthiest men in the world), to develop the Deepwater Railway, a modest 85-mile long short line railroad to access untapped bituminous coal reserves in some of the most rugged sections of southern West Virginia. When Page was blocked by collusion of the bigger railroads, who refused to grant reasonable rates to interchange the coal traffic, he did not quit. As he continued building the original project, to provide their own link, using Rogers' resources and attorneys they quietly incorporated another intrastate railroad in Virginia, the Tidewater Railway. In this name, they secured the right-of-way needed all the way across Virginia to reach Hampton Roads, where a new coal pier was erected at Sewell's Point.
