Is there anyone else that understands the contrapositive, but still doesn't fully understand how the original statement makes sense, i.e. although the necessary condition is there, it doesn't guarantee the stated outcome will happen? I am lost.

Hello. Could someone help me understand why "attempts" is the subject, and not "leaders"? If the sentence was " The opposition leaders attempts to sabotage the vote on the healthcare reform bill will backfire after the story is published. ", wouldn't "leaders" be the subject or would it still be "attempts"?

My hypothesis: The strength of an argument is based on the strength of the support between the premise and the conclusion. However, the conclusions must also be related to the premise. For example, the conclusion in the "Trash" argument is that "Mr. Fat Cat is the guilty party, having intentionally knocked over the bin to access the fish within." How can we prove Mr. Fat Cat intentionally toppled the bin? It is difficult to prove that. Had the conclusion stated yes he ate the leftover fish, it would be a stronger argument having a strong support.

With the "Tigers" argument, more supporting statements/evidence could have been provided to make it a stronger argument.

With the "Disney" argument, a lot of strong statements/evidence compared to the other 2 arguments, is provided.

So i got this question right pre-blind review (I was stuck between E and C and chose E on a hunch), but I chose C during blind review. That was hilariously unexpected. I guess i didn't realize that they weren't talking about restaurants in operation last year and the year before like the accountant was.

Challenge to sale manager's argument: Restaurants that were in operation both last year and the year before were in neighborhoods where customers' income decreased. Therefore, these customers couldn't purchase a lot of food from these restaurants, but it was your new restaurants that were in better neighborhoods with higher income that had more customers and purchases that increased your overall sales. It wasn't because the food is desirable.

Is this question/stimulus making a distinction between pest insect, pest species, and insects?

Hi,

Just in case this helps anyone: for me, the key word was "boosting" i.e. to increase the motivation. Hence, why I chose E, since it mentions the ability to increase their motivation.

So from this example, is it likely that sometimes the necessary condition will also be the conclusion?
