In this excerpt from “a woman’s shortcomings” by elizabeth barrett browning, what is the effect of parallelism?

unless you can muse in a crowd all day
on the absent face that fixed you;
unless you can love, as the angels may,
with the breadth of heaven betwixt you;
unless you can dream that his faith is fast,
through behoving and unbehoving;
unless you can die when the dream is past-
oh, never call it loving!

it creates a passionate rhythm that matches the speaker's message.

it creates a musicality or lilting, which reinforces the speaker's strong passion.

it lends legitimacy to the speaker's claim that she knows what love is.

it adds to the high standard the speaker is claiming one must meet to love another.
