CR Question frm Barron's How To Prepare For The SAT

<p>CR Question 8 frm page 132:
(If u guys have the book, can u help me out here):</p>

<p>8) The word ‘plastic’ in line 10 means:
a)synthetic
b)linguistic
c) consistent
d)sculptural
e)repetitive</p>

<p>The answer was sculptural but I thought it would be synthetic. The passage was on African sculptures but why use plastic here just to replace sculptural? I feel the reasoning given was inadequate, can u guys help me to understand further?</p>
