Grammar questions NEED HLP!

<h1>9) Many people think taxes are too [high, consequently, some of these people do not report]</h1>

<p>My answer: high, therefore, some of those people do not report
Right answer: high;consequently, some do not report
(Note: I know how to use semicolon, but I though you can use ",therefore," as a transition instead of a new sentence kinda deal with a semicolon.)</p>

<hr>

<h1>17)[Crossing and recrossing] the stream, stepping on or over slipper rocks, and [following] a trail [that grew] steeper and steeper, the hikers soon realized [how challenging] their day would be.</h1>

<p>My answer: C) that grew.
Right answer: E) No error
(Note: I though that since most of the choices had "-ing", then grew was wrong, and that it should be "that WAS grOwING".)</p>

<hr>

<h1>25) As a student becomes [familiar with] both early and contemporary Native American Literature, [one] may [notice that] traditional stories [have influenced] recent ones.</h1>

<p>My answer: E) No error
Right answer:B) one
(Note: I checked Pronoun-antecedent. "a student"= singular, "one"=singular so I ignored it, looking back it should be "they"?, but how would i notice that during a actual test?)</p>

<hr>

<p>For the sake of being terse(improving paragraphs), </p>

<h1>32) I chose B) providing an additional example</h1>

<p>Right answer: emphasizing a major point
(Note: I always get the main idea ones wrong, passage is best described as.. how it fuctions...)</p>

<hr>

<h1>35)Which revision would NOT improve ___</h1>

<p>"We know that she tried to learn about everything she found-- I believe she would have much to say about the many countries she lived in."</p>

<p>My answer: Change the dash to a semicolon
Right:Change "much" to "tons of things."</p>

<hr>

<h1>8) It is hard for some young people to believe that women were at onetime not admitted to some [colleges, but they have since become coeducational].</h1>

<p>My answer: colleges, but they are now coeducational
Right answer: colleges that have since become coeducational
(Note: have trouble with since and when related questions like consequently, because, therefore, like when to use which)</p>

<hr>

<p>Just need help understanding why i got it wrong, like is it my process of thinking??</p>

<h1>9: You’re mistaken about therefore. You can’t use it as a coordinating conjunction.</h1>

<h1>17: The participles crossing, stepping and following all modify hikers, and they are all parallel constructions to each other. The clause that begins that grew modifies trails, not hikers, and so it doesn’t need to be parallel to the other elements in form.</h1>

<h1>25: One is an indefinite pronoun, used to refer to a person not previously identified. Because this sentence specifies a singular antededent, student, the correct pronoun would be *he or she<a href=“or,%20if%20you’re%20old%20and%20stodgy,%20just%20%5BI%5Dhe%5B/I%5D”>/I</a>.</h1>

<h1>35: Changing the dash to a semicolon is warranted; a semicolon is the appropriate mark of punctuation to use between two closely connected independent clauses. But replacing much with the much more colloquial tons of things isn’t going to make the sentence better standard American English.</h1>

<h1>8: The problem in this sentence is with faulty coordination that leads to confusing pronoun reference. The form “Women were once…, but they have since…” suggests that women have since…whatever. But women have not become coeducational; colleges have. By making the second clause subordinate–it became an adjective clause modifying colleges–the writer of the revised sentence has made it clear that it was colleges, and not women, that became coeducational.</h1>

<p>Thank you so much for the thorough answer. Like in #17,25,and 8==> how would i MAKE SURE i will NEVER miss these types of questions again? What should i learn up on, and how, google them or something? Like How did you do #17, i just though all verbs would be parallel, but I never thought of asking what modifies what.</p>
