In A, both donating money and volunteering at the hospital are effects of a common cause. The argument infers volunteering from the cause of donating money. TO make it more understandable, the logic error can be explain with a plain example: A helped B with his homework (effect). So A must be nice (cause). So he also clean the classroom after school (effect). The problem of D is that civic-minded and giving fund to orchestra are not two distinct effect of a common cause. Giving fund ==> civil-minded. E is not the same logic. |
