Some.

Contrasted statements in which some and some-not quantified the relation between 2 named sets of definite size, with intersections of definite size. Among 20 undergraduates, preferences among the statements were assessed in terms of (1) grades assigned to them, (2) which predicate Ss supplied to complete each frame, and (3) forced choices between pairs of statements. The preferred statements were the ones in which the subset denoted by the statement comprised fewer than half of the members of the set named by the subject of the statement. It is concluded that some and some-not are complementary ways of achieving the pragmatic goal of restricting attention to less than half of the set under consideration.
