Please explain again

Hi, for a question like this, we want to start by finding the flaw. Our conclusion is that emotions are not physical phenomena. However, we have no idea what makes something a physical phenomenon or not a physical phenomenon. So, in order to make this argument valid, we need something that will prove, from the promises, that emotions are not physical phenomena. E does that, it proves that anything that cannot be explained by the sciences mentioned is not a physical phenomenon.
