Teacher:You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Teacher: Now, understand the problem? Solve this instance: Usually the composition f natural gas is as follows:
Component Typical Analysis(mole %) Range(mole %)
Methane 94.9 87.0 - 96.0
Ethane 2.5 1.8 - 5.1
Propane 0.2 0.1 - 1.5
iso - Butane 0.03 0.01 - 0.3
normal - Butane 0.03 0.01 - 0.3
iso - Pentane 0.01 trace - 0.14
normal - Pentane 0.01 trace - 0.04
Hexanes plus 0.01 trace - 0.06
Nitrogen 1.6 1.3 - 5.6
Carbon Dioxide 0.7 0.1 - 1.0
Oxygen 0.02 0.01 - 0.1
Hydrogen trace trace - 0.02

Specific Gravity 0.585 0.57 - 0.62
GHV(MJ/m3), dry* 37.8 36.0 - 40.2
