Old PSAT Grammar Question

<p>With its 13,677 islands displayed like jewels<a href="A">/U</a> on an exquisite necklace suspending<a href="B">/U</a> between Asia and Australia, the Republic of Indonesia remains<a href="C">/U</a> one of the most beautiful and diverse<a href="D">/U</a> nations on Earth. No error<a href="E">/U</a></p>

<p>The correct answer is (B) - suspending. Why is it B?
I was unable to find answer explanations for this question (from the Wednesday 2006 test). The funny thing is, I answered this question correctly on the test last year, but the 2nd time around...I missed it.</p>

<p>Thanks in advance for any help.</p>

<p>should be: susupended.....because "displayed" was used previously in the sentence.</p>
