Question: 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. <sep>Why do some plants go dormant in winter?<sep>Because it is dying

Answer: No

Question: 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 mestories 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

Answer: Yes

Question: In many parts of the world, trees lose their leaves in autumn. The leaves turn color. Then fall from the trees to the ground. As the leaves are falling, they have kinetic energy. While they are still attached to the trees they also have energy. When they are attached they are not in motion, so how can they have energy? Instead of kinetic energy, they have stored energy. This stored energy is called potential energy. An object has potential energy because of its position. For example, leaves on trees have potential energy because they could fall. They fall because of the pull of gravity. Potential energy can be transferred into motion. Motion can also be turned back into potential energy. Objects have potential energy due to their position. A leaf on a tree branch has potential energy. The leafs energy can be turned into motion as it falls. Once the leaf is on the ground, it has no more potential unless it is lifted back up. <sep>What is an example of potential energy?<sep>Leaves attached to a tree

Answer:
Yes
