Query: Flexibility of Schubert classes   In this note, we discuss the flexibility of Schubert classes in homogeneous
varieties. We give several constructions for representing multiples of a
Schubert class by irreducible subvarieties. We sharpen [R, Theorem 3.1] by
proving that every positive multiple of an obstructed class in a cominuscule
homogeneous variety can be represented by an irreducible subvariety.
