Hi.<br/><br/><i>The only slight problems with this cot were that it had no brakes.</i><br/><br/>The above is the original expression I've found in the Cambridge IELTS 5 textbook.<br/><br/>Shouldn't it be like the following?<br/><br/><i>The only slight <b>problem</b> with this cot <b>was</b> that it had no brakes.</i><br/><br/>Because it is one problem. (It was emphasized by <i>only</i>)
