Query: Comparison of the oscillatory behaviors of a gravitating Nambu-Goto
  string with a test string   Comparison of the oscillatory behavior of a gravitating infinite Nambu-Goto
string and a test string is investigated using the general relativistic gauge
invariant perturbation technique with two infinitesimal parameters on a flat
spacetime background. Due to the existence of the pp-wave exact solution, we
see that the conclusion that the dynamical degree of freedom of an infinite
Nambu-Goto string is completely determined by that of gravitational waves,
which was reached in our previous works [K. Nakamura, A. Ishibashi and H.
Ishihara, Phys. Rev. D{\bf 62} (2002), 101502(R); K. Nakamura and H. Ishihara,
Phys. Rev. D{\bf 63} (2001), 127501.], do not contradict to the dynamics of a
test string. We also briefly discuss the implication of this result.
