Summarize Argument
The author concludes that Joan will have to do the class presentation to pass the course. He supports this by saying that if she’d gotten an A on her term paper, she could pass the course without doing the presentation, but she didn’t get an A on her term paper.
Identify and Describe Flaw
This is the flaw of mistaking sufficiency for necessity. The author treats “A on term paper” as necessary for “pass without presentation.” But in his premises, “A on term paper” is merely sufficient. So not getting an A on the term paper tells us nothing about whether she can pass the course without doing the presentation.
Maybe there are other ways Joan can pass the course without doing the presentation. For example, maybe if she got a B on the term paper, she’ll still pass without doing the presentation.
A
ignores the possibility that Joan must either have an A on her term paper or do the class presentation to pass the course
Like (D), the author doesn't ignore this possibility. In fact, he mistakenly assumes that it’s the only possibility. He assumes that Joan has to either have an A on the paper or do the presentation in order to pass.
B
presupposes without justification that Joan’s not getting an A on her term paper prevents her from passing the course without doing the class presentation
The author assumes without justification that just because Joan didn’t get an A on her term paper, she can’t pass the course without doing the presentation. But maybe there are other ways, like getting a B on the paper, that Joan can still pass without doing the presentation.
C
overlooks the importance of class presentations to a student’s overall course grade
The author isn’t concerned about Joan’s overall course grade. He only discusses whether or not she’ll pass the course.
D
ignores the possibility that if Joan has to do the class presentation to pass the course, then she did not get an A on her term paper
Like (A), the author doesn't ignore this possibility. He claims that if she needs the presentation to pass, then she didn’t get an A on the paper.
E
fails to take into account the possibility that some students get A’s on their term papers but do not pass the course
Other students’ outcomes are irrelevant. The argument is only addressing Joan.
