Which of the following is a promise advertisers cannot make promoting their fitness product?

"you can improve your cardio with our three days per week dance lessons."
"you can strengthen your core completing the ab work series."
"target your belly fat to lose weight there first."
"shape and tone with our muscular endurance videos."

"Target your belly fat to lose weight there first."
 Of the four, this is what advertisers cannot make as a promise when it comes to promoting their fitness product. There is simply no guarantee that anyone who uses their product would lose weight. And should they lose weight, there's no guarantee that the first to be shed off would be the belly fat area.

Ithink the correct answer would be that since the disease is passed by a hand shake and can be cured with antibiotics that it could be an infection. an example could be that once when i was working in a bush camp, i got blood poisoning from blood blisters that got infected. our cook did not wash his hands after going to the bathroom and he passed staphyloccus on to the crew he fed. one other person also got a bad similar infection on the side of his face. i had to be rescued by helicopter and taken to the hospital so i wouldn't die!
