I thought if a M.P. question asked a question, the answer was the answer?

I have the same question. And also, why is it acceptable here to use what is implied? I thought we had to abandon "reading between the lines" and use only what is explicitly stated?

Hi @MelodyWilson and @emilymorganized, Happy to help! While the answer to a question in a main point question stimulus is usually the correct answer, this is not the case here because the answer to the question sets out a condition. The stimulus tells us that it would be right for the government to abandon efforts to determine at what levels to allow toxic substances in our food supply only if it can reasonably be argued that the only acceptable level of toxic substances in food is zero. Government abandon efforts --> Acceptable level is zero Acceptable level is NOT zero --> Government should not abandon efforts The stimulus then goes on to tell us that virtually all foods cannot be said to have a level of zero toxic substances. The sufficient condition in our contrapositive is met. Therefore, we can conclude the necessary condition i.e. the government should not abandon their efforts to determine acceptable levels for toxic substances in our food supply. In this way, the conclusion is implied because it is not directly stated by the stimulus, but it can still be properly drawn by diagramming out the conditional logic used and taking the contrapositive. Hope this helps! Please let us know if you have any further questions.

Thank you so much! Understanding the sufficient & necessary lessons and then going BACK to the main point questions helps a lot!

Wow-Victoria, this was the best explanation out of all the ones I've read! I sometimes forget that these problems are helpful to diagram; not just the logic games.

Very nicely explained!!!!!

Happy you guys got things squared away!
