Example Input: The bar was manned by an expensive humanoid robot. It turned toward Sarah's wave and acknowledged her with a nod, moments later setting a fluted glass of sparkling liquid in front of her. I marveled at the robot's smoothness and coordination. Clearly, it was a high-end model. Sarah transferred the glass to my free hand and pulled me away from the bar for more introductions, with Alexis trailing after us. I spent the evening listening, mostly. Listening and stuffing my face with all the bits of fine food provided. No one minded; Sarah's inner circle was content to fill our circle of couches with plenty of chatter. Ray, a plump man who was grey where he wasn't bald. Zheng, short and dark and lean, with a very intense gaze. He made me a little uncomfortable. Kishori, petite, her hair strung out in a series of braids that reached nearly to her waist. I categorized them based on their appearances, hoping I'd be able to pick them out of the crowd again later. Most of their chatter was meaningless to me—stories of day-to-day activities, how so-and-so had been seen in so-and-so's table at lunch and my wasn't that a surprise, and why hadn't the chef concocted this delectable a selection of appetizers for the dance the other night, but of course those rolled meat pastries reminded one of the pastries back on Earth, didn't they, and this was somehow an interesting fact. After the first half-hour, I stopped expending effort to keep names and stories and gossip straight. I wasn't learning anything useful. I could have started asking questions, but I wanted to get my bearings first. Tonight was for observation. I didn't bother trying to seek out a different group of potentially more interesting people, though. They all looked the same: clusters of social butterflies surrounded by the less apt, the hangers-on, the circle with whom the gossip was shared. <sep>Who are two members of Sarah's inner circle?<sep>Zheng
Example Output: Yes

Example Input: Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition. <sep>What are some things flowing water causes?<sep>Flowing water causes sediment to move
Example Output: Yes

Example Input: U.S. Secretary of State Colin Powell arrived here on Tuesday night for meetings with fellow foreign ministers aimed at solidifying a second front, in Southeast Asia, in the campaign against global terrorism. But he has had to balance that goal with longstanding concerns about human rights abuses in the region. In meetings on Tuesday in Malaysia and Singapore before touching down in this oil-producing sultanate for two days of talks with members of the Association of South East Asian Nations, Powell said he repeatedly raised the issue. "We still believe strongly in human rights, and that everything we do has to be consistent with universal standards of human rights," he said. But at a news conference in Singapore, Powell hinted that the Bush administration was ready to discuss resuming military cooperation with Indonesia, the world's most populous Muslim nation and a sometimes reluctant partner in the efforts to crack down on militant Islamic groups. The United States cut virtually all military links with Indonesia in 1999 after its forces were implicated in the violence that swept East Timor after that territory voted for independence. On Thursday, Powell and representatives of the nations of the Asian group, including Indonesia, are expected to sign a declaration promising cooperation to prevent terrorism by sharing information, blocking funds, tightening borders and making it hard to use forged travel papers. "We recognized that terrorism is a global threat and that the disturbing acts of terrorism and transnational crimes, which continue to threaten world peace and stability, must be tackled by the international community," the ministers said in a communique on Tuesday. Powell is among the representatives from 13 nations outside Southeast Asia, including China, Japan and Russia, that are taking part in the annual meeting of the group's regional forum. Terrorism dominates the agenda, though the possibility of a meeting here between Powell and his North Korean counterpart, Paek Nam Sun, has generated the most news. It would be the highest-level contact between the United States and North Korea since President Bush took office. Powell heads to Indonesia's capital, Jakarta, late on Thursday before finishing a weeklong trip through the region in the Philippines on Saturday. He said that when he arrives in Jakarta, he will have "some ideas and some initiatives" to present to President Megawati Sukarnoputri. Indonesia is already receiving $400,000 in the current fiscal year for civilian training programs and is to receive a like amount next year; and the United States expects to provide an additional $16 million this year to train police officers in counterterrorism. At the same time, the Pentagon is reviewing how to allocate another $17 million in "counterterrorism fellowships," some of which could go to Indonesia. But a senior State Department official also acknowledged that some in the administration and Congress are pushing for more direct military cooperation, which would require congressional approval. "I think they recognize the danger that we all face and I think they have been cooperating more fully with us as time goes by, and I'm quite sure that Mrs. Megawati is committed to this cause," Powell said in Singapore. He met there with Prime Minister Goh Chok Tong, who endorsed the idea of renewed military ties between the United States and Indonesia as an important step in stabilizing that country. <sep>Who is concerned about human rights abuse in Southeast Asia?<sep>Sukarnoputri

No
