Question

read the excerpt from \the tell-tale heart,\ by edgar allan poe.
i talked more quickly—more vehemently; but the noise steadily increased. i arose and argued about trifles, in a high key and with violent gesticulations; but the noise steadily increased. why would they not be gone? i paced the floor to and fro with heavy strides, as if excited to fury by the observations of the men?—but the noise steadily increased.
what is the effect of parallelism in this excerpt?
it emphasizes the narrators paranoia.
it emphasizes the narrators anger.
it emphasizes the narrators grief.
it emphasizes the narrators confusion.

Explanation:

The parallel structure repeats the narrator's escalating, frantic actions paired with the unstopping increase of the noise. This builds a sense of the narrator's growing, irrational fixation on the noise and fear of being discovered, which is core to paranoia. The repeated pattern mirrors his spiraling, obsessive state, rather than just anger, grief, or confusion.

Answer:

It emphasizes the narrator's paranoia.
