GMAT Sentence Correction (SC) | As well as getting away unscathed, Kim managed to gather

Lack of parralelism....

Construction: not only X,but also Y.

X = unscathed ( past participle)
Y = managed to.... (verb)

Hence not parallel.

Correct construction would be:

...not only got away not only unscathed, but also managed to gather.
