obtained from a manhattangmat exam question: does the "would have" portion make it subjunctive? i suppose not because the following verb would have to be present tense. in that case, what verb tense is that, "would have"?
In 1860, the Philological Society launched its effort to create a dictionary more comprehensive than the world had ever seen; although the project would take more than 60 years to complete, the Oxford English Dictionary had been born.
A. would take more than 60 years to complete, the Oxford English Dictionary had been
B. took more than 60 years to complete, the Oxford English Dictionary was
C. would take more than 60 years to complete, the Oxford English Dictionary was being
D. would take more than 60 years to complete, the Oxford English Dictionary was
E. took more than 60 years to complete, the Oxford English Dictionary was about to be
Answer is D. I chose answer B. Can you please explain elaborate what's wrong with using "took more" versus the correct form in answer choice D "would take more"? What are the grammatical principles behind this?
The explanation provided has been copied below for your reference:
(B) This choice changes both the first and second verbs to simple past ("took" and "was born," respectively). In this circumstance, we have two events that took place at different times in the past, which requires use of the past perfect to indicate which event happened first. The dictionary's "birth" obviously happens before its completion, so correct usage would be that the "Dictionary had been born."
(D) CORRECT. This choice correctly uses the simple past "was born." A more complicated past tense is not required because the other verb "would take," is not in the past tense.
Thank you very much!
