I just tried the query myself. The result set contains this URL 	<a href="http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Betteridge&amp;#x27;s_law_of_headlines" rel="nofollow">http:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Betteridge&amp;#x27;s_law_of_headli...</a>, which does not work when entered in the browser. It appears that OP merged this URL with the working URL, that occurs on rank 49. Also notice, that a URL variant pointing to this page occurs on rank 89 again.
