Answer the following question given this paragraph: This passage from a Bach cello suite could be played by any trained musician from any country, because there is agreement as to what the symbols on the page mean. In the same way, molecules are represented using symbols that all chemists agree upon. Q: Molecules are represented by symbols that all who agree on? Choices: - astrologists - geologists - physics - chemists A:
chemists
Answer the following question given this paragraph: A metallic bond is the force of attraction between a positive metal ion and the valence electrons that surround itboth its own valence electrons and those of other ions of the same metal. The ions and electrons form a lattice-like structure. Only metals, such as the copper pictured in the Figure below , form metallic bonds. Q: What is the force of attraction between a positive metal ion and valence electrons? Choices: - liquid bond - covalent bond - galactic bond - metallic bond A:
metallic bond
Q: Answer the following question given this paragraph: Thomas Quine (Flickr:quinet). Bees are important pollinators of flowering plants . CC BY 2.0. Q: What do bees do for flowering plants? Choices: - eat - create - feed - pollinate A:
A: pollinate
Question: Answer the following question given this paragraph: Radiation is the transfer of energy by waves. Energy can travel as electromagnetic waves through air or empty space. The Sun's energy travels through space by radiation. After sunlight heats the planet's surface, some heat radiates back into the atmosphere. Q: What is the transfer of energy by waves called? Choices: - vibration - convection - evaporation - radiation A:
Answer: radiation

Answer the following question given this paragraph: Look at the scissors in Figure below . As you can see from the figure, scissors consist of two levers and two wedges. You apply force to the handle ends of the levers, and the output force is exerted by the blade ends of the levers. The fulcrum of both levers is where they are joined together. Notice that the fulcrum lies between the input and output points, so the levers are first-class levers. They change the direction of force. They may or may not also increase force, depending on the relative lengths of the handles and blades. The blades themselves are wedges, with a sharp cutting edge and a thicker dull edge. Q: Are scissors simple or compound machines? Choices: - lever - neither - simple - compound A:
**Answer**
compound
Answer the following question given this paragraph: Climate and Weather A common misconception about global climate change is that a specific weather event occurring in a particular region (for example, a very cool week in June in central Indiana) is evidence of global climate change. However, a cold week in June is a weather-related event and not a climate-related one. These misconceptions often arise because of confusion over the terms climate and weather. Climate refers to the long-term, predictable atmospheric conditions of a specific area. The climate of a biome is characterized by having consistent temperature and annual rainfall ranges. Climate does not address the amount of rain that fell on one particular day in a biome or the colder-than-average temperatures that occurred on one day. In contrast, weather refers to the conditions of the atmosphere during a short period of time. Weather forecasts are usually made for 48-hour cycles. Long-range weather forecasts are available but can be unreliable. To better understand the difference between climate and weather, imagine that you are planning an outdoor event in northern Wisconsin. You would be thinking about climate when you plan the event in the summer rather than the winter because you have long-term knowledge that any given Saturday in the months of May to August would be a better choice for an outdoor event in Wisconsin than any given Saturday in January. However, you cannot determine the specific day that the event should be held on because it is difficult to accurately predict the weather on a specific day. Climate can be considered "average" weather. Q: What term describes the long-term, predictable atmospheric conditions of a specific area? Choices: - hemosphere - wind patterns - solar activity - climate A:
climate
