QUESTION TEXT: A student has taken twelve courses and…
QUESTION TYPE: Strengthen – Exception
CONCLUSION: The student will probably get another B.
REASONING: The student has gotten a B in most of her 12 courses so far.
ANALYSIS: The past can help predict the future, but it can’t guarantee the future.
So while the conclusion is appropriately hedged (“probably”), it would help to know more about this course, if conditions in the student’s life are the same, etc.
___________
- CORRECT. This weakens the argument. The student might get an A instead of a B.
- This shows the student will probably get a B, no matter what type of course she takes.
- This shows that at least one condition is still true.
- This shows that the student got a B in a large majority of her classes. If she only got a B in 7 of 12 classes (still “most” classes), the conclusion would be less likely.
- This shows the student knows the subject matter at a B level.
