Input: Consider 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

Output: Yes


Input: Consider Input: What if you could drain all of Earths oceans? What would it look like? You might be really surprised. You see that the surface has two main features. It has continents and ocean basins. Continents are large land areas. These are the areas that are mostly above sea level. Ocean basins extend from the edges of continents. They include the ocean floor and Earths deep ocean trenches. You will also notice the ocean floor is not flat. It too has many Continents are much older than ocean basins. Some rocks on the continents are billions of years old. Ocean basins may only be millions of years old. Because the continents are so old, a lot has happened to them! As we view the land around us, we see landforms. Landforms are physical features on Earths surface. These features change over time, but how? There are actually two types of forces at work. <sep>What are the characteristics of continents?<sep>Billion years old

Output: No


Input: Consider Input: The Earth is tilted 23 1/2 on its axis. This means that as the Earth rotates, one hemisphere has longer days with shorter nights. At the same time the other hemisphere has shorter days and longer nights. For example, in the Northern hemisphere summer begins on June 21. On this date, the North Pole is pointed directly toward the Sun. This is the longest day and shortest night of the year in the Northern Hemisphere. The South Pole is pointed The hemisphere that is tilted away from the Sun is cooler because it receives fewer direct rays. As Earth orbits the Sun, the Northern Hemisphere goes from winter to spring, then summer and fall. The Southern Hemisphere does the opposite from summer to fall to winter to spring. When it is winter in the Northern hemisphere, it is summer in the Southern hemisphere, and vice versa. What does this mean for you? If you live in North America, July 1 is usually a very warm day. If you traveled to Southern Australia, you would need a heavy coat. At the equator, the seasons never change. As a result, the average daily temperatures remain the same. There is no summer and winter as we know them. <sep>Why do the hemispheres experience different lengths days and nights?<sep>They have different temperatures


Output: No
