Well, which one is "external?" Headaches and stomachaches are known to exist internally, isolation is setting yourself apart which may or may not be noticed, withdrawal is declining yourself from something, while an outburst of anger is very clearly seen and heard by all. All in all, I would say D.
Your best answer given to here is "B. English Lab" English Lab basically covers all things of and polishing your writing skills. Including grammar/ mechanics and even avoiding plagiarism.
"A. Outlines" can be eliminated because I believe this means the outline of an essay. Its probably about basically filling in an essay body and etc..
"C. Math Lab" can also be eliminated because the words Math Lab indicate learning activity, typically performed by students working to together. Its just about gathering information in teams to answer a real world question and the rest of the steps.
I believe we can eliminate "D". The SQR3 Method is basically a guideline on to become an active and effective reader. It about the method of becoming an aggressive reader that organizes information and answer questions. Has nothing to do with writing.
It could be "C" but I think the best answer is "A". Hoped this helped!
