A
I think this answer to be A. Clustering doesn’t make sense, if anything, it would make things more difficult. Keeping a journal wouldn’t exactly have any certain effect. A is the best option because authors often BRAINSTORM before writhing a paper
It's a compound sentence because it has 'and'.
What the verbs fit, set, and read have in common is that they keep the same form no matter what tense is used.
You can say - I read a book every day. Or Those pants fit you nicely. Or I set the table often.
And if you want to say all that in the past tense, it would look the same:
I read a book yesterday. Those pants fit him nicely a long time ago. I set the table two days ago.
