Dear Bobby, Rita, and Jessica,
You did a good job this time. The passages are easier to follow, and the ideas are nice.
My suggestions are: 1. Pay attention to the sentence structure. Though this is for speaking, you still have to make complete sentences, and mark punctuations at the correct place. 2. You had several difficult words in the script, so please pronounce them as clearly as you can when you speak. Good luck and I am looking forward to your presentation! 
