Science literature is often held back by facts, where you can express yourself, like an expository essay since they are held back by facts as well. Plain fiction is all up to the author with nothing holding them back, like an argumentative essay would be since it’s opinionated.
The correct answer is C. Ordinary characters can do great good. As he himself says it in the book, Bilbo is a Baggins from Bag End and it should remain that way. He is an ordinary person living an ordinary life, but strangely is sucked into a world of magic and adventure. In the end, he does great things and changes the future of the entire world.
A reasonable inference that one can make out of this poem is that you should not be worried about your fate, because at the end people are part of a generation which has its own struggles and at the end, people have to face their own destiny,being courageous, as the previous generations were and have been.
This is the reason why is possible to conclude that the two lines best linked to the theme are:
"Be comforted; the world is very old,
And generations pass, as they have passed"
