<p>1.Now that Michiko (finished) the research, she feels (reasonably confident) (about writing) her paper on the (rise of) the progressive movement in the US.</p>
<ol>
<li><p>Chess players find that playing against a computer is helpful to improve....
i'm pretty sure the answer is "helpful in improving". I get questions like this seldom right and is there some list to study that tells you if an infinitive or a gerund will proceed the verb?</p></li>
<li><p>The students found fieldwork in the state forest more exciting and dangerous than any of them had (anticipated, having to be) rescued by helicopter during a fire.</p></li>
</ol>
<p>A. anticipated, having to be
C. anticipated:they had to be</p>
<p>I picked A. Why is A wrong and C right? What is the rule for using a colon? I thought that it was used to list thing.</p>
<ol>
<li><p>Should be “has finished”</p></li>
<li><p>It should be “helpful in improving their skills” or something similar.</p></li>
<li><p>I don’t know how to explain the logic behind this one, I’m honestly not great at that, but it has to do with tense. I do have a recommendation: try to chop out the extraneous bits of the sentence. Do you see the problem in this sentence?</p></li>

<p>“The students having to be rescued by helicopter during a fire”</p>
<p>silver, can you elaborate on number 1? i always have trouble with perfect tenses.
and i know you posted the link for gerunds and infinitives that follow verbs but i’m on a different computer and i’d appreciate it if you could post it again.</p>
<p>@Randwulf - i appreciate it but i have the answer explanations. I just need more detailed explanations.</p>
<p>“Now that” is always followed by the present perfect tense. </p>
<p>If we approach the issue logically, however, we can still conclude with some confidence that the present perfect tense is most appropriate. The present perfect tense indicates an action done with respect to the present. Michiko is still affected by her having finished the research: it has caused her to feel (present tense) confident about her writing.</p>
