<p>Answer: C
Why is it C? And what gives the clue that it is C (so basically how do you know it is C)? And what is the correct replacement?</p>

<p>Lastly, how do you determine the difference between a past and a past perfect (including other tenses too), meaning if it is in the right usage or not?</p>
<p>The first one is C because all you need is “wrote”. “had wrote” just sounds awkward and unecessary.
The second one is just “busier”. Having the “more” there is redundant.</p>
<p>Thanks but… what I really want to know is Why is it C? And what gives the clue that it is C (so basically how do you know it is C)? And also how do you determine the difference between a past and a past perfect (including other tenses too), meaning if it is in the right usage or not?</p>
<h1>1. This is an error in verb form. You need to use the perfect passive participle, which in this case is “written.” “Wrote” is simple past.</h1>
<h1>2. To form an adjective in the comparative degree, you usually add -er to the positive degree. Sometimes you add “more” in front of the positive degree instead. But you never use “more” and “-er” at the same time. So it should just be “busier”</h1>
