<p>Along the curve of islands known as the Florida Keys lies a reef of living coral, the only one of a kind in the continental US.</p>
<p>A. Along
B. lies
C. the only one
D. a kind</p>
<p>The answer is D. Can anyone explain why?</p>
<p>The only thing I can think of is redundancy.</p>
<p>supposed to be "its kind" referring back the coral</p>
<p>Agree with mikenthemaddog66</p>
<p>this is an english idiom. My daughter had this question as well.</p>
<p>Something is the only one of its kind or something is one of a kind but you cannot blend the two "the only one of a kind"</p>
<p>It's similar to comaprisons involving comparitive degree.
You would say something is more small or smaller but not more smaller. Hope that helps.</p>
<p>StergiaEmman,
I still find it's hard to understand. Can you clarify it? I really hope that you will.</p>
<p>Well lets see if I can help...</p>
<p>when you mention "one of a kind" in this situation, you are implying that any classification of reef is one of a kind, when you're actually talking about a specific classification indigenous to a specific area. I agree with me.duh in the sense that it does sound redundant, since this is one of those questions that requires the use of your ear for what sounds right. I hope this helped.</p>
<p>"one of a kind" already implies that it's unique and cannot be found elsewhere. Adding "the only" reiterates the same thing and hence is redundant. It's like saying the same thing twice. Hope this helps.</p>
<p>redundency and wordiness. I remember t his qeustion from practice. It's b/c the only one already indicates that these islands are the only one of its kind. usually you would say either: the only one, or one of its kind, and not link them both together.</p>
