Input: When you get sick, your body springs to action. Your body starts to fight the illness. Thats why you want to eat right and get plenty of sleep. You need a strong immune system to fight off illness. Plants dont have an immune system. That does not mean they do not get sick. Plants are affected by disease just like us. Typically, their first line of defense is the death of part of the plant. This prevents the infection from spreading. Many plants also produce special chemicals to fight disease. For example, willow trees produce a chemical to kill the bacteria. The same compound is used in many acne products. You can see a picture of a willow tree in Figure Plants may be smarter than we think. No, they cannot talk to each other. They may be able to send messages, though.

Does the response "Soaps" correctly answer the question "The same chemical that willow trees produce to fight infection can be found where?"?

Input: Crusaders, Mamelukes, and Turks: The Crusaders established a feudal Christian state with Godfrey at its head. They built many impressive churches during the term of the first Latin Kingdom of Jerusalem, but in 1187 they were driven out by Muslim forces under the great warrior Saladin. During the Sixth Crusade (1228 1229), the Holy Roman Emperor Frederick II managed to secure Jerusalem for the Christians by negotiation. The Christians, however, could not hold the city. After they lost Jerusalem, a Mongol invasion swept through, and in 1244 the Mameluke dynasty of Egypt took control, ruling Jerusalem for the next 250 years. The city struggled to rebuild from Crusader wars and invasions. Much of the best Islamic architecture in the city was constructed in the Mameluke era, but the past thousand years had taken their toll: Jerusalem was unable to regain the prosperity it had enjoyed in earlier times. In the early 16th century, the Ottoman Turkish Empire was advancing through the Middle East. Jerusalem fell to the Ottomans in 1517, remaining under their control for 400 years. Suleiman the Magnificent rebuilt the walls and gates in the form they retain to this day. Fountains, inns, religious schools, and barracks were constructed. But when Suleiman died, his empire, including Jerusalem, began a long period of decline. The Holy City remained a backwater until the 19th century, when renewed interest among Christian pilgrims made it the destination of thousands of travelers each year.

Input: Not until 1998 did al Qaeda undertake a major terrorist operation of its own, in large part because Bin Laden lost his base in Sudan. Ever since the Islamist regime came to power in Khartoum, the United States and other Western governments had pressed it to stop providing a haven for terrorist organizations. Other governments in the region, such as those of Egypt, Syria, Jordan, and even Libya, which were targets of some of these groups, added their own pressure. At the same time, the Sudanese regime began to change. Though Turabi had been its inspirational leader, General Omar al Bashir, president since 1989, had never been entirely under his thumb. Thus as outside pressures mounted, Bashir's supporters began to displace those of Turabi. The attempted assassination in Ethiopia of Egyptian President Hosni Mubarak in June 1995 appears to have been a tipping point. The would-be killers, who came from the Egyptian Islamic Group, had been sheltered in Sudan and helped by Bin Laden. When the Sudanese refused to hand over three individuals identified as involved in the assassination plot, the UN Security Council passed a resolution criticizing their inaction and eventually sanctioned Khartoum in April 1996. A clear signal to Bin Laden that his days in Sudan were numbered came when the government advised him that it intended to yield to Libya's demands to stop giving sanctuary to its enemies. Bin Laden had to tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave the country. Outraged, several Libyan members of al Qaeda and the Islamic Army Shura renounced all connections with him. Bin Laden also began to have serious money problems. International pressure on Sudan, together with strains in the world economy, hurt Sudan's currency. Some of Bin Laden's companies ran short of funds. As Sudanese authorities became less obliging, normal costs of doing business increased. Saudi pressures on the Bin Laden family also probably took some toll. In any case, Bin Laden found it necessary both to cut back his spending and to control his outlays more closely.

Does the response "Before Bin Laden announced that he can no longer protect them" correctly answer the question "When the Libyan members of al Qaeda renounced their connections?"?

Input: Reuters Holdings PLC said Michael Reupke resigned as general manager to pursue unspecified interests, a move the news organization termed an "amicable separation." Mr. Reupke, 52 years old and a 27-year Reuters veteran, had been the information-services company's general manager for only six months. His appointment to that post, which has senior administrative, staff and policy responsibilities, followed a several-year tenure as Reuters's editor in chief. No successor was named, and Mr. Reupke's duties will be split among three other senior Reuters executives, the company said. In a telephone interview, Mr. Reupke said his departure was for "personal reasons," which he declined to specify. "There is no business reason for my departure," nor any disagreement over policy, he added. He also rejected reports that his departure stemmed from disappointment the general manager's post hadn't also led to a board directorship at the London-based news organization. Mr. Reupke was one of three executives on Reuters's eight-person executive committee who didn't also serve on the company's board of directors. "If I were choosing the people of tomorrow, I would have chosen the people who are now on the board," he said. A Reuters spokesman said the departure reflects "no change in strategy or profits." Mark Shepperd, an analyst at UBS Philips & Drew in London, said, "I suspect (the departure) will be fairly irrelevant for the company. I would be very surprised if his departure signals any change in strategy or change in profit expectations." On London's Stock Exchange, Reuters shares rose five pence to 913 pence ($14.43). In the U.S. over-the-counter market, American depositary shares for Reuters, each representing three shares in the London market, closed unchanged at $43.875. The senior of the three executives who will assume Mr. Reupke's duties is Nigel Judah, 58, finance director and a Reuters board director. Peter Holland, 45, deputy general manager, becomes director of corporate affairs. And Patrick Mannix, 46, international technical manager, becomes director of group quality programs.

Does the response "A disruptive impact" correctly answer the question "What impact has Reupke's departure had on Reuters?"?
