Since a predicate adjective is the first adjective found after a linking verb (in this case 'seemed'), the correct answer is 'docile'.
A=Edgar Poe didn't write "just anything" that would sell. If he did that, we probably wouldn't have ever heard of him for several reasons which are ultimately unimporatant to this question.
B=He claimed his first love was poetry, and he considered himself a poet before a regular, ordinary writer, but given the way the choices are worded, I'd say that B is still, with this in consideration, not the answer.
C=Edgar Poe did fabricate his personal life one time, when he created a backstory for his alias Arthur Gordon Pym.
D=True, he did invent it before Sir Arthur Conan Doyle ripped off Poe's detective C. Auguste Dupin.
E=Edgar Allan Poe was never insane. He was not that kind of man. He was more philosophical and aristocratic. Although in his youth he had toyed with an alcohol vice, he overcame it in his later years. He is only (and falsely) known for an alcoholic past because after Poe died, Poe's editor, Rufus Griswald slandered Poe and re-wrote Poe's biography, altering history away from the truth. Edgar Poe was never the "madman-alcoholic" that some people wrongfully believe he was.
In the beginning there was only Man Never Known On Earth, and he created everything. Then he created the world, but they weren't separate, and everything was dark. Then the Man (never known on earth) created a man who was known as Man With The Power To Carry Light and a woman named Bright Shinning Woman.
And still there was nothing but darkness. Man With The Power To Carry Light began a slow journey east, he came apon a stranger who told him he'd meet many people along the way, and it was his job to teach them. Then a inpatient voice from the east called to the stranger, it told the stranger of two odd coloured deers approaching. The stranger shot the beasts and this caused the earth to turn, the stars to move, and night to become day. The stranger, who we come come to know as Star That Is Always Moving, went off to follow the wounded deer. Man With The Power To Carry Light stayed by the shore and watched the sun rise from where the mysterious voice had came from. He heads home and notices he travels faster in the day. That night he sees three stars and concludes they were a man and two deers.
After the light the people multiplied, as Star (That Is Always Moving) had said. Man With The Power To Carry Light and Bright Shinning Light went from village to village, and taught the people how to survive.
Then Man With The Power To Carry Light told them they must offer of they game they caught to the moon, stars, and other supernatural beings. He then left him and became the morning star. In order to live a long a life when they saw him rise in the sky they were all to bathe in the river.
