<p>Please explain the answer and what could have been a better alternative to the answer. Thanks!</p>
<p>1.) Advances in seismology HAVE LED some scientists TO SPECULATE that soon we WILL PREDICT earthquakes AS ACCURATE AS we predict the weather. NO ERROR Answer: AS ACCURATE AS</p>
<p>2.) HAVING HEARD both local candidates give speeches, Tina WAS CONVINCED that neither of them WERE LIKELY
TO BE ELECTED in the primary. NO ERROR Answer: WERE LIKELY</p>
<p>3.) The weather in Arizona and New Mexico is like SOME PARTS OF California, but DESPITE THIS similarity THERE ARE important climatic differences within these regions. NO ERROR Answer:SOME PARTS OF</p>
<p>1) Change to AS ACCURATELY AS because accurate here should be an adverb --> ACCURATELY
2) Change to WAS LIKELY since neither should be followed by a singular verb.
3) Uhm, this one I am not so sure, probably it is too wordy? I guest it should be replaced by PARTS OF, just cross out the word SOME… not so sure…</p>
<p>Oh wow! Problems 1 and 2 I already know somewhere in my mind, but I guess I totally didn’t see it. Thanks! And as for 3, the answer key says B… perhaps by having “parts”, it is implied that it’s “some” of California. </p>
<p>Number three is a comparison error. The sentence tries to compare “weather” to “parts of California.” The sentence should compare “weather” with “weather in parts of California.”</p>
<p>Like CaptainAmerican said, the neither is considered singular. It’s easier to see when you know that “neither” is really a shortened version of “neither one.” Neither one WAS likely to be elected. </p>

<li>In triangle ABC (imagine an equilateral-looking triangle that is NOT drawn to scale with angles labeled a on bottom left, b on top, and c on bottom right), if a>b>c, which of the following must be true?</li>
</ol>
<p>I. 60 < a < 180
II. 45 < b < 90
III. 0 < c < 60</p>
<p>The answer is I and III only. </p>

<li>In the sequence below, the first term is 4, the second term is 7, and each term after the second term is the non-negative difference between the previous two terms. If the nth term is the first term of the sequence that is equal to zero, what is the value of n?</li>

<p>WRITING
The bolded words are incorrect and should be changed.
According to one study, half of the adults in the country can neither read such basic material as newspaprers OR fill out job applications. Should it be “nor”? .</p>
<ol>
<li><p>Despite the historical society’s lengthy deliberations about the restoration of the old museum, there REMAINS several unresolved questions about the soundness of the building. I thought “remains” was normal since “questions” was plural.</p></li>
<li><p>The committee members regained a sense of unity and purpose only when the mayor issued a mandate that clearly established the task BEFORE IT. Should be “BEFORE THEM?” I honestly was confused with the phrase, but I think I’m right with that assumption.</p></li>
<li><p>Widowed in 1859, novelist Margaret Oliphant succeeded to TO PROVIDE for her own and her brother’s children with the profits from the books… Should it be “in providing”?</p></li>
<li><p>The phrase “The enormous sums bid on Mary’s impressionist paintings demonstrate…” seems weird to me. Can you say “enormous sums bid?”</p></li>
</ol>
<p>Please give me a better replacement for the bolded words/why it’s grammatically incorrect. Thank you!</p>
<ol>
<li><p>Sorry, I know how to solve this one, but I cannot clearly explain it in English ( I am an Vietnamese - 9th grader ). However, you can simply base on the given in-equation and the sum of three angles (180) to logically assume the correct answer.</p></li>
<li><p>It is easy to recognize that we need to apply the absolute value in this sequence. For me, I just take the absolute value of every number and count the result. Just do the math, it will take you little bit more time, but it is better than spending time reasoning, right?</p></li>
</ol>
<ol>
<li><p>Yes, it is “nor”.</p></li>
<li><p>I think the word “deliberations” determines that “there” here is a plural noun, so it should be followed by “remain”</p></li>
<li><p>I think “it” here is kinda ambiguous. Probably, the sentence contains ambiguity…</p></li>
<li><p>“the enormous sums bid” is normal since “bid” acts as a past participle verb. You can simplify the sentence like this: “The enormous sums THAT ARE bid on Mary’s impressionist paintings demonstrate…”. Because we have shortened this sentence by crossing out THAT ARE and the second clause is passive, “bid” stays the same. You get it? Yah,…sorry, I am pretty wordy. </p></li>
</ol>
<p>Ok, I have come up with a good explanation for Q.1</p>
<ol>
<li>a>b>c and a+b+c=180 ( a,b,c are angles of a triangle)</li>
</ol>
<ul>
<li>We have a>b>c, so let’s say: b=a-x and c=a-y ( 0<x,y< a)</li>
<li>We also have a+b+c=180 (basic stuff)</li>
<li>Substitute the values of b and c above:
a+b+c=180
=> a+(a-x)+(a-y)=180
=> a+a+a-x-y=180
=> 3a-(x+y)=180
=> 3a=180+x+y
=> a= (180+x+y)/3
=> a= 60 + (x+y)/3</li>
<li>Since x and y are all greater than 0 => (x+y)/3 >0
=> 60+ (x+y)/3 > 60
=> a > 60.</li>
<li>a has to be smaller than 180, obviously. </li>
<li>There we go, 60<a<180</li>
<li>Apply the same stuff for c and you will get your answer. =D></li>
</ul>
The verb “remains” is talking about what? “Questions.” Since questions is plural, the verb should be “remain.” There REMAIN questions. </p>
<p>
The sentence is using “before” in a context like this: “The mayor established the task before [the committee members]” So the pronoun has to be “them.” </p>
<p>
Yes, a gerund goes here. </p>
<p>
It’s like saying “The large amount INSCRIBED on the scroll…” or “The small sticker FOUND on the apple…”</p>
<p>As for those math questions, are they official SAT questions or are they from a practice book?</p>
<p>Thanks, CaptainAmerican (I’m Viet as well, 11th grade) and humbuggs. Greatly appreciated it! Your explanations are always thorough. Those are real PSAT math questions.</p>
<p>And CaptainAmerican, I got lost when you said “so let’s say: b=a-x and c=a-y.” Why do we do that?</p>
<ul>
<li><p>Because a>b, we can find b by subtract “x” value from a. ( e.g: 5>2 => 2= 5-3 — here, a=5, b=2 and x=3)</p></li>
<li><p>Same thing, a>c, then c=a-y (e.g: 5>1 => 1= 5-4 —here, a=5, c=1 and y=4 )</p></li>
<li><p>x and y here are numbers satisfying 0<x,y<a</p></li>
</ul>
<ul>
<li><p>I just use x and y as values to find b and c depending upon a. I just hope the explanation is easier to understand. Since you are Vietnamese, b và c là hàm số, còn x và y là biến( thay đổi đươc nhưng phải thoả điều kiện.) Còn a có thể coi là 1 hằng số ( không thay đổi). Mình mới học xong Toán 9 nên chỉ biết giải thích vậy thôi. :D</p></li>
