  true of the structure of cycad cones?

  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

  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.
