Q-1)  One minor mistake.
      In page4, right side, 15th line
      Outside the nucleus, ..... with momenta larger than 500 MeV/c
      -->
      Outside the nucleus, ..... with momenta smaller than 500 MeV/c

A-1)  We correced.

--------------------------------------------------------------------
Q-2)  In Figure 3, you limit the pi^0 momentum range at 900 MeV/c,
      however you include more higher momentum bin in Figure 4 where
      you integrated all events above 900 MeV/c at the highest
      momentum bin.
      [1-1] Inconsistency between Fig3 and Fig4.
      [1-2] No explanation about the highest momentum bin in Fig4
            which includes all events with higher momentum.

A-2)  We added a dashed-line and an arrow to Fig3 and Fig4.
      We also added the following sentence in the caption of Fig3.
      "The highest momentum bin in each figure integrates
       the events above 800MeV/c."

--------------------------------------------------------------------
Q-3)  Page 4 right column, arround line 29
      " CC pi0 production where an outgoing muon and mesons
        except a single pi0 have low momenta "
      sounds funny. It is diffcult to write but I suggest such as
      " CC pi0 production where accompanying muon and mesons
        have low momenta "
      There another "except single pi0 " style there.

A-3)  We modified the sentence according to your suggestion.

--------------------------------------------------------------------
Q-4)  Page 6 left column 5 lines from bottom. 
      "the true/reconstruction fiducial difference" 
      sound funny. You already use " fiducial volume correction"
      in page5, why don't we write simply
      "By applying non-numu CC backgound subtraction, fiducial
       volume correction and detection efficiency correction,
       the number.."

A-4)  We modified the sentence according to your suggestion.

--------------------------------------------------------------------
Q-5)  The 1kt detector is not a "imaging" water Cherenkov detector.
      We do not image the Cherenkov light using a mirror.
      So, it should be refered as simply "water Cherenkov detector"
      without "imaging".

A-5)  We removed words "imaging".
