Part 3. Below are some symbolized arguments in standard form. Some of them are fallacies of Affirming the Consequent (AC), Denying the Antecedent (DN), or Undistributed Middle (UM). Identify each by writing the abbreviation in the blank. If an argument is none of these forms, write N. This section asks you to stretch what you know into a new kind of problem. Use what you know from the homework and sections 1 and 2 of this exam to solve them. (4 points each, 20 total) 1. __________ ( B & C ) ? D ~ D____ ~ (B & C) 2. __________ ( B & C ) ? D ~ ( B & C ) ~ D 3. __________ ~ C ? A C_______ ~ A 4. __________ C ? I I________ C 5. __________ D ? C D ? B____ C
Explanation / Answer
1. UM
the argument commits Fallacy of Undustributed middle term as there is no link created between the major and minor premises. Accordingly, in this argument nothing follows beyond the plain statements of the premises themselves.
2. AC
The argument commits fallacy of affirming the consequent as it asserts that the minor premiss, ‘D’ will occur even if the antecedent ‘(B&C)’ does not hold true.
3. DA
The given argument is fallacious as it asserts the consequent would hold true from the relation with the antecedent.
4. AC
In this argument, the fallacy of affirming the consequent is made as it asserts that the consequent C would hold true irrespective of its relation with the premises.
