Anyway, when you click on the link, you will notice that there are 36 different pages ~ each with more than 20 articles, so the good news is that you've got lots of options. Next, notice that for almost all of the articles, it estimates how long it will take you to read it. Most are 20 to 25 minutes. Some are 15 minutes. Others are over an hour. I'm asking you to read a minimum of 45 minutes combined for both blogs, so if you accomplish that requirement all in one single article, that's totally fine. However you slice it up is up to you.
In terms of the writing, I'm looking for 150 words for each article that you read: a short 75-word paragraph of summary and a short 75-word paragraph of your personal response. If you decide to "kill two birds with one stone" and read one of the articles that is 45 minutes or longer, then just do one longer 300-word entry: half summary and half response.
Two more things: there are a few pieces on this site which lean more on the adult side of things. I'm asking you to use your best judgement and go with something that you would say is appropriate for school. PLEASE clearly label your entries, so I can easily figure out which is blog #6 and which is blog #7. Finally, you do not have to do these at the same time or in the same comment. Do one now and one later if you like.
