<p>1) (Like many) people, Luana believes that parents can foster musicl ability in small children (out of) (playing) classical music for them while (they are) infants.</p>
<p>The book says the answer is B (out of), any explanation ?</p>
<p>2) The Mayan River, which (extends down) the eastern coast of Mexico, (has many hidden) caves, one (of which) is larger (than the size of) Monaco</p>
<p>The answer is D, any explanation ?</p>
<p>thx in advance</p>
<p>Perhaps 1) should be by. That’s my guess. Nevertheless, it sounds awkward.</p>
<p>2) This might be redundancy.</p>
<p>
</p>
<p>It should be by.</p>
<p>
</p>
<p>This sentence is incorrect because it is comparing a country to another country’s size.</p>
<p>Ex.
Joey runs faster than the speed of me.</p>
<p>Yes, the speed is related with speed, but the sentence is comparing Joey with the speed of me.</p>
<p>I find it interesting that you only asked two questions… but the title reads four.</p>
<p>As LoseYourself points out the problem with 2 is redundancy. The comparison initiated with the word “larger” implies size. So you can say:</p>
<p>The Mayan River, which extends down the eastern coast of Mexico, has many hidden caves, one of which is larger than Monaco.</p>
<p>Can someone help me with this one?
Each of the authors A)who was honored at the city’s new bookstore’s open house
B)had been writing for more than twenty years and C)had published at least two national best-sellers during D his or her career. No error </p>
<p>I thought it should be “who were honored”, but it’s actually no error. Why?</p>
<p>It’s E (no error) because the sentence is correctly written. Each is singular.</p>
