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.
it can be infer from the paragraph 1 (就是上段）that even when paint was sprayed by mouth to make a hand stencil
我选的是  artists stenciled more images of the dominant hand than they did of the weak.
答案是 the stenciled hand was the waker hand.
感觉答案应该在这红字中，答案当时我也考虑过，文章中也提到了，但是我感觉应该找这句话 one can assume that the dominant hand assisted in the operation的同义改写，就选了错误选项。
2 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.
这句话啥意思？

求高人解答

整段都说，weaker hand才会印上去，红字说就算用嘴吹。。也还是印副手。而主手要辅助（类似拿管子，我的理解）。就算不管到底怎么吹怎么引的，反正even though就说，和之前的论点是一样的，也就是副手才能印上去。所以还是选
the stenciled hand was the weaker hand
后面半句应该是说 我们必须假设所有手掌都是正着印的(手心印上去)-因为左手手背印和右手手心印看起来是一样的。。这句话的确很。。。费解。。看了3遍才明白。。
