type B:


line 21: This paper is about cold nuclear matter effects.
         Is QGP really so important to bring it in the first paragraph? 
         spell out how "hot medium effects" and "(effects due to the QGP)" are related.

line 43: say why/in which respect this measurement is new.

line 79: tower jargon or introduce in section 2 ? Motivate why the extra requirement 

line 124: does this mean the correction factor is 1.0/0.9 ?

line 197: need introduction of A (and definition of cross section) before (or while) presenting figure 2.
Right now A is coming with figure 4 (line 203).

line 207, 238: consistent with unity (how consistent is it really?)

line 210: really in the production or in the suppression ?

lines 217: explain this in the introduction, that the measurement of this is the purpose of this paper.
          "reminiscent" why not consistent ?
 
line 222: elobarate

lines 237: should one not rather say that the data are consistent with the expected trend towards unity for large pt.
