Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right.

Question: "When and why do plants go dormant?"

Answer: "They do so as the days get shorter, in order to survive"

Response: yes

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.

Question: "Why did Bin Laden tell the Libyans who had been part of his Islamic army that he could no longer protect them and that they had to leave Sudan?"

Answer: "The government advised him that they intended to yield to Libya's demand to stop giving sanctuary to its enemies"

Sometimes a full Moon moves through Earths shadow. This is a lunar eclipse . During a total lunar eclipse, the Moon travels completely in Earths umbra. During a partial lunar eclipse, only a portion of the Moon enters Earths umbra. When the Moon passes through Earths penumbra, it is a penumbral eclipse. Since Earths shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse. So unlike a solar eclipse, it doesnt get dark on Earth. Instead it gets dark on the Moon. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse.

Question: "What is a lunar eclipse?"

Answer: "When the full move passes through moon's shadow"

Response: no

One look at Fred Rooney, and you just know he's the good guy. A trace of childish innocence in his face gives the lanky Bethlehem lawyer a Jimmy Stewart-like quality of quiet trust. In black jeans and button-down shirt, he's a kind of folk hero in the south Bethlehem melting pot where he's crafted a law practice catering to working-class families - mostly Latino - in the shadow of the hulkish remnants of Bethlehem Steel. A two-hour drive away, at City University of New York Law School in Queens, Rooney spends several days a week helping upstart lawyers develop storefront practices that, like his, provide legal representation to folks who can't afford a $250-an-hour legal counselor. Kristin Booth Glen, the law school's dean, took one look at Rooney and knew he was the right person to head the innovative Community Legal Resources Network. ''Fred's so low-key, he's Midwestern in effect,'' says Glen, a former New York Supreme Court judge. ''He captivates people, he inspires loyalty.'' For bringing legal representation to the poor and a host of other social causes, including finding medical care for seriously ill children in Latin America, the Moravian College Alumni Association has chosen Rooney for its prestigious Haupert Humanitarian Award. The award, given to only a select few alumni, will be presented at 7:30 tonight at a reception on Moravian's Priscilla Payne Hurd campus. Moravian, where he was an undergraduate in the early 1970s, inspired Rooney's deep sense of social justice. The son of a Bethlehem Steel executive in New York, he came to the Bethlehem campus from an affluent upbringing on Long Island. The young Rooney might have set his sights on Washington, D.C., like his uncle, former U.S. Rep. Fred Rooney of Bethlehem. After all, politics run in the Rooney family. His brother, state Rep. T.J. Rooney of Bethlehem, is a power in the state Legislature and the Democratic Party. But on a trip to Colombia when he was a junior at Moravian, the child of privilege saw human suffering, malnutrition and poverty the likes of which he had never imagined. ''I couldn't understand why we live this way and they live that way,'' Rooney recalled. ''It's been the guiding light of my life ever since.'' After graduating in CUNY Law School's first class in 1986, he took a job with Lehigh Valley Legal Services.
