<p>ok, so would these sentences be considered gramatically correct?</p>
<p>“This might help to lower blood cholesterol and reduce the risk of heart disease.”
“I flew from America to meet my relatives and visit places.”</p>
<p>Or do they have to be like:</p>
<p>“This might help to lower blood cholesterol and <em>to</em> reduce the risk of heart disease.”
“I flew from America to meet my relatives and <em>to</em> visit places.”</p>
<p>thanks! help appreciated =]</p>
