<p>Hey, I think you both got all the answers right. I have a minute so I'm going to see if I can clarify the grammar. It's kind of complex, so I wouldn't worry about mastering it. I hope this helps you more than it confuses you. :) </p>
<p>Before I jump in here I'm going to give you the quick version:</p>
<p>a) You might be able to raise your score slightly by mastering the present perfect verb tense, which would also help you master words like "since."</p>
<p>b) If you don't have lots of time and you're not shooting for an 800, don't stress too much about specific verb tenses: instead, try replacing difficult words with simple ones and using your ear. You guys both got all the right answers even without understanding <em>exactly</em> what was going on. That's true of most top scorers.</p>
<p>Here goes!</p>
<ol>
<li>After the prince characterized modern architecture (as ugly-A), he (has been-B) (severely-C) criticized for having been (so outspoken-D) in public.</li>
</ol>
<p>B: The verb "has been" is the present perfect. We use this tense in two ways: a) to describe an action or duration that started in the past and has continued to the present; b) when we don't know or don't care at what time the past action actually took place. In the second case, the emphasis is on a completed action in the present. So, for instance, you might say, "HAVE you SEEN that movie?" and someone else might answer "No, I HAVEn't SEEN it." In this dialogue, we don't care <em>when</em> the movie was seen or not seen, we only care <em>if</em> it was seen or not seen. So we use the present perfect. On the other hand, we would never say "What HAVE you DONE yesterday?" "Well, last night I HAVE GONE to a movie." The reason the second example sounds so weird is that we never use the present perfect when we're talking about an action that happened at a specific time (i.e. yesterday/last night).</p>
<p>The purpose of the sentence is to tell us <em>when</em> the prince was criticized, and your verb choice should reflect that purpose. You can see how this works if you simplify the above problem by replacing the hard-sounding words in the questions with easy-sounding words: "After the prince characterized her as ugly, he has been criticized. . ." sounds really funny. Once you change the words, you can tell that the verb "has been" needs to be "was." </p>
<ol>
<li>I have gone (to-A) (only one-B) football game (after-C) I (graduated-D) from high school.</li>
</ol>
<p>This is very related to the problem above, but it's not identical. Here, the word "after" is wrong; you actually need "since," because you are talking about a range or duration of time: however many weeks, months, or years it's been since you graduated. (Since that time continues right up to the present, it's correct to use the present perfect here). Phrases with "after" is normally used to describe definite events (usually ones that are already over). For instance, if somebody says "She did yoga after she gained thirty pounds freshman year," you kind of assume that she has stopped doing yoga, right? But if someone says, "She has done yoga ever since she gained thirty pounds freshman year," you kind of assume that she's still doing yoga. We use the word "since" in the second example sentence to show that we're talking about a duration that continues to the present. </p>
<p>You might also notice that, when we use the word "since," we also use that HAS BEEN/HAS DONE tense. . . the present perfect. </p>
<ol>
<li>The radio station received (the most number-A) of calls from listeners (on the evening-B) (it-C) aired a discussion of (the music of-D) Aretha Franklin.</li>
</ol>
<p>As DrumsAreForGirls said, you can't say "most number." It could be "greatest number"; it could also be simply "the most calls." This is just an idiom thing. We use "most" primarily to describe adjectives (it was the most difficult test ever) or to refer to a majority of something (most of the girls in our class can't whistle). We wouldn't say "the majority of the number of calls"; that's weird. We would say "the majority of calls." So, equally, we don't say "the most number of calls"; we simply say "most calls." </p>
<ol>
<li>When the village elders (present-A) recommendations, (there is-B) (hardly ever-C) any opposition (against-D) their proposals.</li>
</ol>
<p>Idiom (prepositions). The word "opposition" needs the preposition "to": . . . there is hardly ever any opposition to their proposals. There are lists of noun/preposition pairs in most prep books and also online, if you feel like memorizing them, but in my experience you usually get a poor return on investment for memorizing those lists unless your score is already in the solid 700s.</p>
