Query: Equivalence Principles, Lense-Thirring Effects, and Solar-System Tests
  of Cosmological Models   In this talk, we review the empirical status for modern gravitational
theories with emphases on (i) Equivalence Principles; (ii) Lense-Thirring
effects and the implications of Gravity Probe B experiment; (iii) Solar-System
Tests of Cosmological Models.
