Helps a bit, but couldn't the readers' response by potentially not reading the magazine or being "suspect" of its integrity also classify under "the readers' response to ads"? The way I see it, the readers are still "responding to advertisements they see in the magazine" via finding it "suspect," not reading it, etc.

This one is so hard lol. Even deciphering between D and E is super difficult. Could anyone #help me understand their differences better? Thanks

Thank you!

Could someone help me by identifying the differences between necessary and sufficient assumptions? #help (Added by Admin)
