Query: N=1 Conformal Supergravity and Twistor-String Theory   The physical states of N=4 conformal supergravity in four dimensions occur in
twistor-string theory by Berkovits and Witten(hep-th/0406051). We study two
alternative versions of twistor-string theory based on the B-model of weighted
projective space WCP^{3|2} and based on a certain construction involving open
strings. The spacetime fields described by the twistor superfields contain the
physical states of N=1 conformal supergravity from above N=4 superspace
approach.
