<p>For #19–
You “put” questions “to” people-- just as you “put” it “to” the test. Put the idea “to” rest. She “put” me “to” shame. Put goes with “to” not “toward.”</p>
<p>Think outside the box. Loop it around. Yo.</p>
I recognize that this is an old thread, and I apologize for reviving it. However, it does irk me to know that your question remains unanswered. I do happen to have an official answer key to the questions from the first test you posted, and although you most likely don’t care now, I will post the answers with brief explanations anyway for anyone else who happens to stumble upon this thread and is in need of the correct answers.
14) Answer: B. I got this wrong, and put "No Error." In hindsight, I realize that "better suited" is the grammatically correct way to say this.
19) As a poster above pointed out, the answer is B, since you do not put a question 'toward' something, you put a question 'to' something. The sentence used some unfamiliar phrasing.
28) E, No Error. If you google "enter into," it comes up as "become involved in (an activity, situation, or matter)." This would make sense, as the readers are becoming immersed in the fictional world of their book (aka a SITUATION).
29) E, No Error. I mistakenly put D because I thought that "so late an hour" should be corrected to "such late an hour." Turns out they're both grammatically sound.
Hope that helps

Grave digging again but for #14, “Jocelyn, my friend (since) junior high school, believes she is (more well suited) to a career in the sciences (than to) the business career her parents (have urged her) to pursue”, @ColonelBoss is right. You cannot place “more” next to an adjective that already has a comparative form. The comparative form of “well” is “better”, so not only is “better suited” more concise, it is also the grammatically correct answer.
But notice I said “more concise” (XP), because “concise” does not have a comparative form (conciser?). So “more” is only used to place a word in the comparative sense if that adjective does not already have a comparative form.
the 19th question has an answer of C. The word towards" is wrong… You don’t put something towards someone, you put TO.
Sorry, the answer B.
