1. Since students work together the group is accountble not an individual.<br/><br/>I found 'accountable' in my dictionary. The usage of it is this: ~ (to sb) (for sth).<br/><br/>But #1 found from my book doesn't look like it follows my dictionary.<br/><br/>Don't you use 'accountable' in #1 like ~~ is accountable not <b><u>as</u></b> an individual?
