Re: born vs. complete, "born" is being used as a metaphor (of course, since a dictionary can't literally be born :) ). In this case "born" means it was started. Logically, the start needs to occur before the completion.
Answer B changes the first verb from "would take" to the simple past "took." When using past tense, we default to the simple tense unless a reason exists to use one of the more complex tenses (in which case we are required to use the more complex tense). In this case, two simple past tenses in the same sentence indicate that the two events took place essentially simultaneously, but that is not the case. First, the book was "born" and then, some 60 years later, it was completed. This kind of situation requires the past perfect tense (used to indicate which of two past events that took place at different times occurred first and which occurred second).
For the "future" issue, there are actually two different circumstances here. The first half of the sentence (before the semi-colon) is set in the past tense. The second half is written from the point of view of the timeframe of the first half. At the point that it was launched, it was also born - these mean the same thing - but it was not yet completed. From the viewpoint of the time it was launched (in the past), the completion is sometime in the future.
Answer E puts the "birth" in the future and the completion in the past, which is illogical. Answer D correctly puts the "birth" in the past (simultaneous with launch) and the completion in the future from the point of view of the "birth."
Make sense?
Hi Stacey,
I perfectly agree with your explanation that we should use *complicated tenses* when the order of actions is not clear and has to be made clear. In rest all cases, you should restrict to use Simple Tenses.
Don't you think that presence of *60 years* itself makes the sequence of the actions and the time frame of the actions clear and they should use only simple tenses and thus I feel B is correct.
Can you please throw some light on the above?
Thanks,
Shankey
