Hi, this is what I'm trying to describe: <br/><br/>An ability that I showed at a specific point in the past. The ability, however, still exists. <br/><br/>So this is my sentence (or not a sentence so much as a sentence fragment): <br/><br/>"Displayed a knack for sniffing out problems before they arose/arise"<br/><br/>Which is it? And if possible, why? Thank you.
