　　托福阅读词汇题：assisted in

　　【Paragraph 1】We all know that many more people today are right-handed than left-handed. Can one trace this　same pattern far back in prehistory? Much of the evidence about right-hand versus left-hand dominance comes from　stencils and prints found in rock shelters in Australia and elsewhere, and in many Ice Age caves in France, Spain, and　Tasmania. When a left hand has been stenciled, this implies that the artist was right-handed, and vice versa. Even　though the paint was often sprayed on by mouth, one can assume that the dominant hand assisted in the operation.　One also has to make the assumption that hands were stenciled palm downward—a left hand stenciled palm upward　might of course look as if it were a right hand. Of 158 stencils in the French cave of Gargas, 136 have been identified as　left, and only 22 as right; right-handedness was therefore heavily predominant.(Which Hand Did They Use?)
