Write a question about the following article.

When I realized that my entries are becoming shorter and less important , I stopped . It 's not because I want to store up emotions to create a beautiful entry but because I am losing my social life and it ( writing entries ) might get my grades down . So , I planned to change . Wrote some now funny plans and goals to reach .

Question:
Why might entries bring their grades down ?
[i] Because writing takes up too much of their time . [ii] Because they spend too much time online as it is . [iii] Because they would rather focus on other things . [iv] None of the above choices .
