<p><a href=“Opposite%20to”>QUOTE</a> most people I know, Annie, a good photographer (herself), actually (enjoys seeing) the photographs that her friends take (on their) vacations.</p>
<p>Answer is A</p>
<p>Not very particular (in) nesting (sites), house wrens (may nest) in birdhouses, mailboxes, building crevices–even in pockets (of) hanging laundry.</p>
<p>Answer is A</p>
<p>Both these questions test idiom knowledge. The first one should be “opposite of…”
although “opposite to…” is acceptable in some dictionaries. Im assuming CB doesn’t think it’s correct.</p>
<p>The second one should be “…particular OF…”

<p>There are almost no idioms involved here.</p>
<p>“Opposite” as an adjective does not apply to people. “Opposite to” and “next to” are commonly used to describe shapes and things in geometry. If two people’s personalities are similar, you would not say that one person is “next to” the other.</p>
<p>That being said, “opposite of” and “opposite to” are both acceptable phrases. Just because one is not allowed in one context does not mean it is an idiom. It is a simple matter of defining.</p>
<p>“the opposite of the word”
“an opposite to a word”
“the heir of the throne”
“an heir to the throne”</p>
<p>“The opposite” is specific. You use “of” to attach something specific to something general. A word has a specific opposite: a specific opposite of the word</p>
<p>“An opposite” is not specific. It can be given an active preposition like “to”</p>
<p>I could say that a gift is “a gift to you.” Once you receive the gift, it will be “the gift of you” because it is in your possession. </p>
<p>The only idiom involved here is “opposite” as a noun (i.e, two people can be “opposites” of each other). This is the only idiomatic expression. You cannot change this idiom to an adjective and say two people are opposite to each other. But if you could, it would be opposite to not opposite of because it is an adjective. Something is of something else if it is a noun (possession).</p>

<p>That is, X reduces Y.</p>
<p>There is only a clause. “By” connects a phrase and a clause: “by X, you get Y.”</p>
