Nancy's presentation fell flat when she discovered that the audience had little or no background on her topic. what did nancy do wrong?

she did not research about the audience that will be present in her presentation.

Explanation:for her to only find out during presentation that the speech did not relate to her audience clearly tells us that she didn't do research on her audience before even preparing for the speech.

One needs to find out more about the people they are going to be delivering a speech for before preparing the speech so that what ever point one presents will actual capture their interest and they can even relate to it so a background check on who you are going to be presenting to is very important.

they used personification to make the truck seem mean and violent.

hope this !
