<p>Grammar questions:</p>
<p>1) The campus newspaper does not print as much world news as does my hometown newspaper.</p>
<p>VS The campus newspaper does not print as much world news as my hometown newspaper.</p>
<p>Why is there a need for 'does'?</p>
<p>2) Journalists should present a balanced view of the news but should also stir discussion and unsettle complacent thinkers.</p>
<p>VS Journalists should present a balanced view of the news but also stir discussion and unsettle complacent thinkers.</p>
<p>The parallelism in this case should be "present" with "stir" or "should present" with "should stir". Why?</p>
<p>3) He like to be able to cycle and run. VS He likes to be able to cycle and to run.</p>
<p>The parallelism in this case should be "cycle" with "run" or "to cycle" with "to run". Why?</p>
<p>Quite confused by parallelism. Thank you :)</p>
