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. 

Example Input: Coal is burned at a furnace. The resulting heat energy is used to heat water. The heated water is turned into steam. The steam drives a generator. Electricity is produced. 
Example Output: How does a coal-powered power station generate electricity?

Example Input: Movements of tectonic plates causes the creation of volcanoes. These volcanoes erupt. Volcanic mountains are formed from the eruption. Sometimes tectonic plates crash into one another or ride over one another. These plates sometimes fold and buckle, which forms Fold Mountains. Sometimes fault blocks are raised or tilted, and they form Block Mountains. 
Example Output: How are mountains formed?

Example Input: Human beings burn fossil fuels (oil, gas, etc.). Carbon dioxide from the burning fossil fuels enter the atmosphere. The make-up of the atmosphere changes. Some energy from the sun cannot escape back through the changed atmosphere. The earth begins to heat because of the extra trapped energy. Human beings cut down trees. Human beings do not re-plant the trees. Trees cannot help take the extra carbon dioxide from the atmosphere. The extra trapped energy starts to change the earth's short term weather. Eventually the long-term climate patterns start to change. 
Example Output:
Describe the process of global warming
