<p>Many changes occurred while she was president of the (college, and they increased its educational quality as well as effectiveness.)</p>
<p>a) same as original statement
b) college; these changes increased its educational quality and effeectiveness
c) college; these changes increased both the educational quality and effectiveness of the college</p>
<p>The answer is c and I got it right. But I would like to know why options b and a are wrong. The explanation from the college board for why b is wrong is that "its" is ambiguous. </p>
