<p>Here's the question</p>

<p>Identifying error</p>

<p>A person who uses hand tools to accomplish only such tasks as hanging pictures and fixing window shades need not purchase the most cutting-edge power tools developed for professionals. </p>

<p>A. to accomplish
B. such tasks as
C. need not
D. most cutting-edge
E. No Error</p>

<p>The book picks E. Actually, "a person" takes a singular verb form and so shouldn't the wrong answer be C ? Should "need not" be "needs/needed not" instead? Thanks for help!</p>
