Why does the goal suddenly change from "Identify and bracket the premise and conclusion" to "background information and observation" in 6.1 then right back to "identify and bracket..." in 7.1 and on? I think a distinction must be made. Also, like the other replies state, this is a lot of repetitive questions. I get repeating things to get the idea, but some are just the same thing with one or two words changed. I like the idea, but if this were maybe 20 questions max (where each question asked something different, or at least every other question, rather than restating the question before it) this would be a great quiz.

Additionally, question 11.1 is problematic. There's no argument, but there IS a premise and conclusion. I do not believe it to be the author's conclusion as they state "after comparing genetic material...they concluded". If a trick question was going to be thrown in, I think discussion on the possibility of no argument should be discussed a bit more in previous lessons.

Great exercises!
