25. The passage suggests that which of the following is
    true of the structure of cycad cones？
    （A） The structure of cycad cones provides conclusive
    evidence in favor of one particular explanation
    of cycad pollination.
    （B） The structure of cycad cones provides evidence
    concerning what triggers the first step in the
    pollination process.
    （C） An irresolvable discrepancy exists between what
    the structure of most male cycad cones suggests
    about cycad pollination and what the structure of
    most female cones suggests about that process.
    （D） The structure of male cycad cones rules out a
    possible mechanism for cycad pollination that is
    suggested by the structure of most female cycad
    cones.
    （E） The structure of male cycad cones is consistent
    with a certain means of cycad pollination， but
    that means is inconsistent with the structure of
    most female cycad cones.
    26. The evidence in favor of insect pollination of cycads
    presented in lines 2-4 would be more convincing if
    which of the following were also true？
    （A） Only a small variety of cycad species can be
    successfully transplanted.
    （B） Cycads can sometimes be pollinated by means
    other than wind or insects.
    （C） Insects indigenous to regions to which cycads are
    transplanted sometimes feed on cycads.
    （D） Winds in the areas to which cycads are usually
    transplanted are similar to winds in cycads'
    native habitats.
    （E） The transplantation of cycads from one region to
    another usually involves the accidental removal
    and introduction of insects as well.
    27. The passage suggests that which of the following is
    true of scientific investigations of cycad pollination？
    （A） They have not yet produced any systematic evi-
    dence of wind pollination in cycads.
    （B） They have so far confirmed anecdotal reports con-
    cerning the wind pollination of cycads.
    （C） They have， until recently， produced little evidence
    in favor of insect pollination in cycads.
    （D） They have primarily been carried out using cycads
    transplanted from their native habitats.
    （E） They have usually concentrated on describing the
    physical characteristics of the cycad reproductive
    system.
