Question 8

How is B not the exact same flawed reasoning as the argument we were initially given? even when he diagrams it, the diagrams are identical in reasoning yet the conclusion drawn is different. I'm confused as to why and how they are different.

never mind I got the answer from another discussion post

Hi Marco,

Glad the other post was helpful! In case anyone looks to this post in the future, the stimulus is flawed becasue it confuses siffienct and necessary. We could diagram it as

If P -> Obligation for trash cans
BUT Not P -> no obligation.

Put plainly, the argument fails to consider that the city might have an obligation for other reasons.

B Tells us
If Birthday -> Balloons
but Not Ballons (yet) -> not birthday.

In the stimulus we simply negate the sufficient condition, but B tries to take the contrapositive, but mistakes the time frame.

If we are to be extracting the logic for diagram, should we not be focusing on that? If we cannot rely on the diagram we take time out to draw; focusing on other factors such as time frames and obligations for other reason, what then is the essence of diagramming?

The diagram of answer choice B is the exact same as the diagram for the passage. I was very suprised when the instructor glossed over it as not the right answer. I still do not understand the answer you gave in the discussion post.

Why can't we rely on our diagram here?

The passage is as follows:
If PL - otc
But not PL - not otc

In order words
If X then y
But since not X then not y

B is as follows:

If birthday then balloons
But since not balloons, then not birthday.

Or
If X then y
But since not y, then not X.

See in the second statement the X and Ys are flipped in b. They are not flipped in the initial. The diagrams are not the same.
