As its sales of computer products have surpassed
those of measuring instruments, the company has
become increasingly willing to compete for the mass
market sales they would in the past have conceded
(A) they would in the past have conceded to rivals
(B) they would have conceded previously to their
(C) that in the past would have been conceded
previously to rivals
(D) it previously would have conceded to rivals in
(E) it would in the past have conceded to rivals
Now my question. A) and B) are obviously wrong as they use the plural pronoun 'they'.
C) Why is this choice incorrect. Just becuase it is in passive voice?
D) Don't we need a "which", to begin this clause? If not "why"? The OG says that the modifier "in the past" is misplaced - that is understood.
E) Same question - does it not need a "which" before it?
