黃金閱讀Which Hand Did They Use? - 英檢

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.

Paragraph 2：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
○ the ideal source of lighting for most engravings
○ the fact that a left hand stenciled palm upward might look like a right
hand
○ the prevalence of outlines of left hands
○ figures in prehistoric art holding objects with the right hand



我的問題是，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.

這一句話不是說，左手掌向上被拓印，看起來就像是右手。所以答案為什麼還是B？
B不就是我引這段話的意思嗎？
