10. Scientists predict technological changes in the next century, they will be as dramatic as was the development of the transcontinental railroad in the last century.
...
(E) century as dramatic as</p>
<p>This question kind of threw me off, because I thought the answer (E) was incorrect. Should not it be 'century will be as dramatic as' because it is referring to something that did not happen yet and will happen in the future?</p>

6. Rilke, the great German poet, could not continue his search for angelic spirits until he can rely on a strength greater than his own.

<li>Surface mining is safer, quicker, and cheaper than deep mining, but the greater is its toll in human misery.
...
(B) it has a greater human misery toll
...
(E) its toll in human misery is greater</li>
</ol>
<p>pg 414: That the changes in the next century haven’t happened yet is implied when you say (E). Your suggestion is also correct; the “will be” in choice (E) is implied.</p>
<p>pg 416: (B), because the sentence is talking about the nineteenth century, which happened in the past, so “will be” should be “was.”</p>
<p>pg 417:
26. (C), because the sentence says that the harmful effects (Note: “effects” is plural) of noise pollution have become known, so “has” should be “have.”</p>
<ol>
<li>(C), because it should be “preoccupation with.” That’s just something you have to remember.</li>
</ol>
<p>pg 429
6. (B) because the answer should match “could not continue his…” So we use “could rely on…” instead of “can rely on…” If the sentence had started, “Rilke, the great German poet, can not…” then (A) would be correct.</p>
<ol>
<li>(E). Both choices say the same thing, but (B) is awkward. There is no such thing as a “greater human misery toll.”</li>
</ol>
<p>pg 414: Are you sure that it is not necessary to specify future tense? I always thought that the SAT emphasized tense as an important topic.</p>
<p>pg 416: Although the sentence is talking about the nineteenth century, how do you know that the sentence was written after the nineteenth century? The original text could have been written before the nineteenth century, which would make the sentence correct.</p>
<p>pg 414: Well, the SAT does emphasize tense as an important topic. I’m just saying that answer choice (E) is one way to say your longer suggestion.</p>
<p>pg 416: I haven’t thought of that! That’s a very good point. You’re right. If the sentence were written in the eighteenth century, it would be correct as it is. They shouldn’t have that question on the practice exam. I guess you’d just have to assume that the sentence was written for today.</p>

Scientists predict changes as dramatic as the development of the railroad, or; Scientists predict changes will be as dramatic as the development of the railroad. I think the sentence needs the ‘will be’ otherwise it just sounds completely wrong.</p>
<p>The word “predict” already implies it will happen in the future. “As dramatic as the development of the railroad” is just a modifier – think of it as an adjective. You wouldn’t have any problem with the sentence, “Scientists predict major changes,” would you? It’s the same thing.</p>
