The poem uses free-verse structure.
The two main ones are (distress) and (Eustress) distress means bad and eu means good but I would put time stress, anticipatory related stress, situational stress, and encounter stress
A. is not the answer since 'both' does not contrast, but instead shows similarity
b. is not the answer either. it does not indicate contrast (or anything, really) and the second part of that sentence shows similarities between coal and petroleum.
c. however is usually used to introduce a statement that contrasts. This happens in this paragraph, too. The first part of the statement tells how petroleum is made from dead microorganisms. The second part of the statement is introduced with "on the other hand," a common phrase used to compare and contrast two things or ideas. The sentence then states that coal was made from dead vegetation. These are two characteristics that are different about coal and petroleum that are portrayed in a contrasting manner. Therefore c. however is the correct answer.
D. is not the answer. "because" is simply used to explain an idea.
