confused sentence

by sleepwalker1914 » Sun Jul 17, 2016 1:30 am
Despite advancing in an absolute sense, the productivity of Zel-Tech's workforce has fallen significantly behind that of competitor workforces: by up to thousands of dollars.

The sentence comes from Manhattan prep sentence correction 5th edition, my question is:

Is "productivity" the subject of this sentence? If it's true, it seems that it doesn't make sense with the modifier "advancing in an absolute sense".

Thanks in advance.

I agree that "advancing... productivity" is - though not completely nonsensical - certainly an inelegant modifier. We scrapped it for the 6th edition of our guides. (We tend to update and amend a lot of our examples with each edition, though the overall content does not change).

You're absolutely right - "productivity" is the subject.
