In this task, you are given a paragraph, and your task is to construct a question from the given passage. Construct question in such a way that (i) it is well explained in the paragraph, (ii) the words may/may not be present in the paragraph, (iii) it should start with what/how/describe. Avoid creating a question that (i) is just relevant to one or two sentences, and (ii) not relevant to passage. 

Input: Consider Input: During evaporation the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. Water vapor in the air gets cold and changes back into liquid, forming clouds, which is called condensation. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. Water falls back to the earth in the form of rain, hail, sleet or snow. When water ends up on land, it will either soak into the earth and become part of the "ground water" for animals or plants to drink. It may also run into the oceans, lakes, or rivers where the cycle starts again. 

Output: Describe the process of precipitation


Input: Consider Input: Animals pull a fruit off a plant or pick a fruit up from the ground. Animals eat the fruit. Animals drop some seeds onto the ground. Animals eat some seeds. The seeds are in the animal's waste. The waste goes onto the ground. There are seeds on the ground in different areas away from the plant. 

Output: How do animals help plants disburse seeds?


Input: Consider Input: Electrical signals in the brain travel through nerves to muscles. Two types of proteins exist in filaments in the muscles. The filaments move when the brain instructs them to. The motion of the filaments cause the muscle to shorten and contract. Opposing pairs of muscles exist in order to provide the necessary range of motion. 


Output: How do muscles work?
