Seyfert 2 nuclei appear to live in galaxies with an elevated rate
  of star formation compared with field galaxies or the host
  galaxies of Seyfert 1 nuclei.  It is not clear what causes this
  difference.  The elevated star formation might be associated
  directly with the feeding of matter into the AGN, with the
  Seyfert 2 galaxies revealing a particular stage in this process
  that Seyfert 1s are not currently in.  Alternately, the elevated
  star formation might arise from a common trigger -- for example,
  an interaction with another galaxy -- that establishes an axi-
  symmetric potential to feed the AGN and also initiates elevated
  star formation in the galaxy.  Again, the difference between
  Seyfert 1s and 2s might indicate a different stage in this
  process.  To test these possiblities, we have selected a complete
  sample of 17 Seyfert galaxies with strong star formation and
  which can be well resolved by ISO.  We have determined the
  specific observations required to resolve these galaxies that are
  NOT included in the guaranteed time and we propose to obtain
  these data.  This proposal roughly doubles the number of galaxies
  in our sample that ISO will resolve, and will provide enough
  examples to determine the typical proximity of the regions of
  elevated star formation to the active nuclei.
