How can you guarantee that your talk or speech will be interesting to your audience? is this good advice? why or why not? justify your response.

If you want to make sure it's interesting, you have to cater your speech/talk to your target audience. This is good advice. A 15-page detailed Powerpoint presentation with note cards would do as much good when presenting to kindergarteners as a water hose would do good in a flood. But, say, it was a fire, then the water hose might come in handy. In our case, your boss at the business meeting would find your Powerpoint much more interesting than kindergarteners would. 

Hope this helps! Have a nice day :)
