<p>He was [(A)somewhat] uncertain about [(B)how to use] the new machine and [(C)asked for] [(D)more specific] instructions be sent.
The answer is C
but why is it C?</p>
<p>It should be "asked that", "asked for" doesn't sound right does it?</p>
<p>"asked for" is when you're requesting a noun.
E.g. She asked for a handphone.</p>
<p>"asked that" is when you're requesting a verb/action
E.g. She asked that I stay over tonight.</p>
<p>what about this one?</p>
<p>In the eighteenth century a (simple) method of musical notation (helped to make) (music more popular) than in (any century)</p>
<p>why is it D?</p>
<p>It should be "any OTHER century." It's making a comparison.</p>
<p>any other century and any century are basically the same thing i think..</p>
<p>^ there is a difference....</p>
<p>If you say any century, it is all inclusive and therefore doesn't make a valid comparison. If you say any other century, then the eighteenth century isn't included and thus you can make a comparison.</p>
