In a speech about AIDS and HIV, one of the speaker's main points describes ways to respond to the devastating news that you or someone in your family is HIV Negative. You know that HIV Negative means that someone isn't infected with the virus that leads to AIDS. How can you provide feedback to let the speaker know that you are confused

Speaker can be asked for the occurrence of positive and negative HIV conditions.

Explanation:

Here, the speaker can be asked to define two conditions when a person is HIV positive and another for HIV negative. If the speaker is able to distinguish between the two then it can be concluded that the speaker knows about the technicality of the infection that is positive state is indicative of infection and negative state is indicative of no infection condition from human immunovirus.  Then speaker mistake can be correct by asking this doubt by showing a state of confusion between the two states.

umm there is no difference

great question btw!
