✦ Synopsis

This paper deals with polarized pairs (Jr, L), where 3~ is a nonsingular projective threefold and L is a very ample line bundle on it, such that for one smooth member.4 E ILl, one has x(_4) = 2.

A large class of pairs whose adjoint line bundle is nef and big was indirectedly studied by Beltrametti and co-workers. We add some more information, both in this general case and also when the adjoint line bundle fails to be nef and big.
