Hi All, <br/><br/>Please help me find any grammatical mistake on the sentence below. <br/><br/> "K. is proud of her own abilities to mediate disputes more than any of her other strengths."<br/><br/>My book says that "more than" is wrong but somehow I don't see any problem with it. Can anyone explain to me please?<br/><br/>Thanks in advance,<br/><br/>Simplicitie
