In the movie, a teenager <u>wanting</u> to pursue a singing career meets resistance from his storng-willed father.<br/><br/>1. 'Wanting' underlined above can be replaced by <i>who wants</i> or <i>who wanted</i>, can't it?<br/><br/>2. What I was wondering is if that replacement can occur in every situation.<br/><br/> (for example, <i>who want(s)</i> or <i>-ed</i> and <i>wanting</i> is always interchangable regardless context?)
