We all know that many 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.
Cave art furnishes other types of evidence of this phenomenon. Most engravings, for example, are best lit from the left, as befits the work of right-handed artists, who generally prefer to have the light source on the left so that the shadow of their hand does not fall on the tip of the engraving tool or brush. In the few cases where an Ice Age figure is depicted holding something , it is mostly, though not always, in the right hand.

5.All of the following are mentioned in paragraphs 1 and 2 as evidence of right-handedness in art and artists EXCEPT
A.the ideal source of lighting for most engravings
B.the fact that a left hand stenciled palm upward might look like a right hand
C.the prevalence of outlines of left hands
D.figures in prehistoric art holding objects with the right hand.

我选的C，可答案B，我觉得C也没提到过啊，哪里提到outline了啊？还有B提到过啊. 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 .

第二题
It can be infered from 第一段 that even when paint was sprayed by mouth to make a hand stencil
A there is no way to tell which hand was stenciled
B. the stenciled hand was weaker hand
c. the stenciled hand was dominant hand
D.artists stenciled more images of the dominant hand than they did of the weak

答案是B，我也选对了，不过我不是根据第一段判断出来的，是做到后面发现的，求问从第一段怎么能看出来

求各位兄弟姐妹们指点一下，谢谢各位了

第五题：
C选项其实是对应第一段最后一句话
B选项虽然文中提到，但是 one also has to make the assumption that hands were......有没有发现其实是个assumption......但是选项却说是the fact......而且这个也不是说的right-handedness
我是这么排除的 = =
第二题：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. 第一句说如果左手是模版，那就暗示画家是右撇子。后面one can assume后面说dominat hand 是协助操作，那stenciled hand也就是模版手肯定是弱手了
我是这么理解的.......
