Question

read the excerpt from \the adventure of the mysterious picture.\ how was this vile nervous fit, for such i now persuaded myself it was, to be conquered? i determined to force myself not to look at the painting but to undress quickly and get into bed. i began to undress, but in spite of every effort i could not keep myself from stealing a glance every now and then at the picture; and a glance was now sufficient to distress me. even when my back was turned to it, the idea of this strange face behind me, peering over my shoulder, was insufferable. how does the excerpt exemplify gothic fiction? by revealing an unhinged psychological state by describing a scene of blood and gore by depicting the triumph of reason over the irrational by illustrating the confused plans of the narrator

Explanation:

Gothic fiction often explores psychological states, especially those that are unhinged or filled with anxiety and fear. The narrator's nervous fit, inability to stop looking at the painting, and the insufferable idea of the face behind him all show an unhinged psychological state. There is no mention of blood and gore. The narrator is not showing the triumph of reason (he can't stop looking at the painting despite trying). And the confused plans are not the main focus - the psychological distress is.

Answer:

by revealing an unhinged psychological state
