    The spectacular disintegration of a comet last year in full view of ground- and space-based telescopes provided new insights into how comets form and may thus force a rethinking of the role of comets in the delivery of organic compounds to the evolving Earth.

    (A) The spectacular disintegration of a comet last year in full view of ground- and space-based telescopes provided new insights into how comets form and may thus force
    (B) The spectacular disintegration of a comet last year in full view of ground- as well as space-based telescopes,provided new insights into how comets form and thus possibly forcing
    (C) When a comet's spectacular disintegration occurred in full view of ground- and space-based telescopes last year, it provided new insights into how comets form and thus may possibly force
    (D) Last year, in full view of ground- and space-based telescopes, a comet's spectacular disintegration provided new insights into how comets form and thus possibly forcing
    (E) Last year, in full view of ground- as well as space-based telescopes, the spectacular disintegration of a comet has provided new insights into how comets form and may thus force

    A VS E. Why is HAS PROVIDED wrong? We could have ongoing studies, which continuously provide newer information

    I was down to A & B and finally took A

    B seemed to be trying to modify smth which cant be modified

    why "has provided" is wrong? my opinion is that the disintegration which happened in the past was a single event (which occured in a certain short time frame), so the usage of "has provided" is wrong. I guess "had provided" would be better.

    what is wrong with E??

    I felt E > A...I felt A got over cooked as it is not in sequence

    In this sentence we are dealing with a particular year (last year), so we use the simple past tense
    present perfect is used when some action happens in some unspecified time in the past and its effects
    continue in to the present

    Also choice E screws up the meaning of the sentence. It is suggesting that in the presence of telescopes the disintegration provided insights. This is illogical
