The first progress in combating infection was made in 1847 by the Hungarian doctor Ignaz Semmelweis, who, despite ridicule and opposition, introduced compulsory handwashing for everyone entering the maternal wards, and he was rewarded with a plunge in maternal and fetal deaths, however the Royal Society dismissed his advice.
Meaning: Doctor Ignaz Semmelweis made the first progress in combating infection in 1847. He reduced maternal and fetal deaths by introducing compulsory handwashing for everyone entering the maternal wards. He was ridiculed, opposed, and dismissed by the Royal Society.
A) who, despite ridicule and opposition,
introduced compulsory handwashing for everyone entering the maternal wards, and
he was rewarded with a plunge in maternal and fetal deaths, however the Royal Society dismissed his advice.
The clause
he was rewarded with a plunge in maternal and fetal deaths is illogical. We can say
his effort was rewarded with a plunge in maternal and fetal deaths. Perhaps the clause could be
he was rewarded for a plunge in maternal and fetal deaths. Apart from this, this sentence is a run-on.
he was rewarded with a plunge in maternal and fetal deaths and
however the Royal Society dismissed his advice are two main clauses joined by a comma. Eliminate A.
B) who
reduced maternal and fetal deaths by introducing compulsory handwashing for everyone entering the maternal wards and
was ridiculed,
opposed, and
dismissed by the Royal Society
Correct. This option is abridged, so I was quite skeptical about its correctness as it omits a number of details that were in the main sentence. I couldn't find any option that is better, hence my choice of option B. The parallelism is okay.
reduced is rightly parallel to
was ridiculed, opposed, and dismissed.
C) who reduced maternal and fetal deaths by introducing compulsory handwashing for everyone entering the maternal wards despite ridicule, opposition, and dismissal by the Royal Society
This option is very similar to option B. The only difference is that option C does not express the ridicule, opposition, and dismissal by the Royal Society parallel to reduced maternal and fetal deaths. Instead, it is expressed as a contrast. I, however, prefer the parallel structure in option B compared to option C. I will patiently wait for the OE.
D) who was ridiculed, opposed, and dismissed by the Royal Society, even though he introduced compulsory handwashing for everyone entering the maternal wards and was rewarded
with a plunge in maternal and fetal deaths.
The parallelism is okay between introduced and was rewarded. But the meaning of
he was rewarded with a plunge in maternal and fetal deaths is still illogical as in option A. We can, therefore, stand on this ground to eliminate option D. I would have opted for this option if not for the illogical meaning portrayed by
he was rewarded with a plunge in maternal and fetal deathsE) who
introduced compulsory handwashing for everyone entering the maternal wards and
was rewarded with a plunge in maternal and fetal deaths, despite ridicule, opposition, and dismissal by the Royal Society
The same illogical meaning exists in option E as well.
I don't know whether this can be a ground to eliminate options A, C, and E but according to the VAN principle, when it comes to concision, verbs are preferred followed by adjectives, and finally nouns. When you look at how the fact that Dr. Ignaz was ridiculed, opposed, and dismissed by the Royal Society, Options B and D use adjectives (i.e. verb-ed modifiers) while options A, C, and E use nouns. So in a way, option B can be considered more concise than option C.
I am going with option B.
