I am interested! Thank you!

In the third paragraph, the author is countering the advocate's claim by stating that' [computer] conferences fall short of communities." He is making the claim that computer conferences cannot be thought of as communities.

Answer choice C says "counter the claim that [computer conferences cannot be thought of as communities.]" If the author were to counter "[computer conferences cannot be thought of as communities]," it would mean "the computer conferences can be thought of as communities.

This answer choice would actually support the advocate's claim and counter the author's claim. The author is not trying to counter his own claim in this paragraph, so it is incorrect.

Rather, the author uses "conferences can be both respectful and supportive" as support for his claim though conferences are similar in some aspects (respect & support), "conferences fall short of communities". (E)

You will use the front camera on your phone, so the image displays like a mirror. You will then point the screen towards your laptop, so the proctor can look at your laptop display/keyboard. They will also have you hold your laptop up and spin it around your room. I believe we are required to show all of this to limit cheating. I hope this helps. Good luck!
