Ex Input:
The Vice President stated that he called the President to discuss the rules of engagement for the CAP. He recalled feeling that it did no good to establish the CAP unless the pilots had instructions on whether they were authorized to shoot if the plane would not divert. He said the President signed off on that concept. The President said he remembered such a conversation, and that it reminded him of when he had been an interceptor pilot. The President emphasized to us that he had authorized the shootdown of hijacked aircraft. The Vice President's military aide told us he believed the Vice President spoke to the President just after entering the conference room, but he did not hear what they said. Rice, who entered the room shortly after the Vice President and sat next to him, remembered hearing him inform the President, "Sir, the CAPs are up. Sir, they're going to want to know what to do." Then she recalled hearing him say, "Yes sir." She believed this conversation occurred a few minutes, perhaps five, after they entered the conference room. We believe this call would have taken place sometime before 10:10 to 10:15. Among the sources that reflect other important events of that morning, there is no documentary evidence for this call, but the relevant sources are incomplete. Others nearby who were taking notes, such as the Vice President's chief of staff, Scooter Libby, who sat next to him, and Mrs. Cheney, did not note a call between the President and Vice President immediately after the Vice President entered the conference room. At 10:02, the communicators in the shelter began receiving reports from the Secret Service of an inbound aircraft-presumably hijacked-heading toward Washington. That aircraft was United 93. The Secret Service was getting this information directly from the FAA. The FAA may have been tracking the progress of United 93 on a display that showed its projected path to Washington, not its actual radar return. Thus, the Secret Service was relying on projections and was not aware the plane was already down in Pennsylvania. <sep>Where was United 93 presumably headed?<sep>Oregon

Ex Output:
No

Have you ever seen an egg? Some animals do not have live births. Instead, they lay eggs. The eggs contain the embryo. The embryo matures in the egg. With time, it will hatch. Some animals hatch and do not need care from their parents. They are ready to live on their own. Other animals will still need the care of their parents. Sea turtles break out of their shells. They immediately walk to the ocean. They do this with no help from an adult. Birds stay in the nest for many weeks. They are cared for by their parents. They leave the nest when they are strong enough to fly. Some animals give birth to live offspring. Animals like horses, cows, and whales give live birth. Their offspring are born looking like mini adults. <sep>What happens to baby birds?<sep>They stay in their nests for weeks, being cared for by their parents until they are strong enough to fly

Ex Output:
Yes

In her storage room-turned-office, Jennifer Baum works under an expanding leak that is causing the ceiling to turn brown and crumble. Mold grows in the buckets positioned to catch the water. She shrugs it off. Outside her office she has taped up a clear plastic suit, and a sign that reads, "All employees must don protective gear before coming in." Such is life in limbo. Nearly a year after Sept. 11, the Legal Aid Society-the lawyers for New York's poor and homeless-remains, well, homeless. The nonprofit has been barred from returning to its 90 Church St. headquarters, across from the World Trade Center site, because of environmental concerns. Legal Aid has uncomfortable company. More than 11,500 New Yorkers continue to work out of temporary space, according to analysis by Manhattan-based real estate brokerage TenantWise.com Inc. and Crain's New York Business. That's 8% of the 137,000 workers who lost their offices or access to them when the Twin Towers collapsed. Legal Aid's 450 displaced attorneys and staffers have spent the past 12 months spread among previously unused spaces-some unused for good reason-in the nonprofit's other offices. It could be another year and a half before they return to their old desks. They have contended with difficult working conditions as demand for Legal Aid's services is on the rise because of Sept. 11 and the deteriorating economy. The civil division is spread among a few boroughs. Their papers and documents, some 20,000 boxes worth, are stuck in a storage facility in Linden, N.J. "I am counting the days till we can have all the parts back in one place," says Steven Banks, Legal Aid's associate attorney in chief. In the memories of the exiled workers, the old office has achieved mythical proportions. They say the wood paneling and rugs had the ability to cool emotions and lift spirits. The Legal Aid office on Montague Street in Brooklyn Heights, where 65 displaced workers have cobbled together space amid the faded and scratched walls, looks more like a bargain basement. <sep>How much more time will it take for the workers of Legal Aid Society to return to their old offices?<sep>18 month
