One sentence completion problem! please!

<p>Hi, I am really confused with this level 2 sentence completion question. I keep overthinking it.</p>

<p>-Although certainly talented, the child could not really be called _<strong><em>: there was nothing particularly </em></strong> about his achievements.</p>

<p>a) virtuoso…precocious</p>

<p>d) prodigy…exceptional</p>

<p>I chose A, because I thought the ‘child’ wasn’t mature enough to be called a virtuoso.</p>

<p>But, D is the answer.</p>

<p>Can anyone give me clear explanation? thanks.</p>

<p>virtuoso is mainly used to describe a person who has extraordinary ability in arts, which is not mentioned in this sentence, prodigy is mainly used to describe a child with unusual talent. In the second blank, exceptional would make more sense because his achievements are used to compared with those of real prodigies.</p>
