<p>It’s a tricky level 5 question. I will be glad if you help me with that. </p>
<p>Passage:
A blog can seem like a waste of time to some, since there is no guarantee readers will come and comment. Maintaining it with new posts and an interesting layout can seem like a chore. Why does someone bother to create a blog if it isn’t to peddle a product or to get in touch with consumers? [ The principal reason to blog is because you have something to say," claims one expert on blogging. “While the cadre of readers may be small, it is not really how many sets of eyeballs are reading your material that’s important, but who the eyeballs belong to. Blogs are written by influencers, and it is often other influencers that read them.”]</p>

(A) analyze a hypothesis
(B) account for a phenomenon
(C) advocate an action
(D) pose a question
(E) qualify a claim </p>
<p>I was struck when I found out that the answer is B … So why? Why not E? What does choice B mean?</p>
