<p>Endowed with powerful bodies, big claws, and sharp teeth, mountain lions are “one of” the most formidable creatures native to north america. </p>
<p>“One of” is incorrectly used here. How do I fix this to make it correct without fixing anywhere else?</p>
<p>some of?
mountain lions are plural but I’m no expert; I only made a 2160 on my SAT</p>

You’re right. It’s illogical to use “one of” when the noun “lions” is a plural noun.</p>
<p>mountain lions are among the most formidable creatures</p>
<p>Areelperson’s answer would work, too.</p>
<p>What practice guide is telling you “one of” in the sentence is incorrect? You can use “one of” when referring back to a specific group of things, such as mountain lions in the sentence, and thus there is not an error.</p>
<p>One of is, indeed, incorrect in the practice test lol</p>
<p>The plural of one is “ones”. So while purists may frown on that use, it is correct grammatically. A common use of the plural of one is “loved ones”.</p>
<p>I prefer “among” to “ones” in the example. But “one” is certainly wrong in formal English.</p>
