A vocal opponent of the unequal distribution of wealth, the itinerant activist has spent time in several countries across the world, railing against the callousness and injustices of governments, the negligence of the upper classes, and trying to forge a transnational people’s movement.
(A) railing against the callousness and injustices of governments, the negligence of the upper classes, and trying to forge a transnational people’s movement
According to this option railing is common for all three terms, which cannot be possible as "railing against trying" makes no sense.
(B) to rail against the callousness and injustices of governments and the negligence of the upper classes, and trying to forge a transnational people’s movement
Again parallelism error since "to rail" is not parallel to "trying.
(C) railed against the callousness and injustices of governments, the negligence of the upper classes, and tried to forge a transnational people’s movement
Incorrect tense. Also parallelism error since "railed against tried" doesnt mean anything
(D) railing against the callousness and injustices of governments and the negligence of the upper classes, and trying to forge a transnational people’s movement
Correct option.
Callousness and injustices are parallel. The negligence is parallel to the callousness. "Trying to forge" is parallel to "railing against".
(E) railing against the callousness and injustices of governments, the neglecting of the upper classes, and trying to forge a transnational people’s movement
Incorrect Parallelism. "railing against trying" doesnt mean anything.
