Suddenly, a ditty strezzle boofed into George’s grep. Tony blaired, “Oh George, that ditty strezzle is boofing your grep!”After reading and studying the paragraph, and without referring to the paragraph, please answer the following questions:Physics 207: Lecture 1, Pg 9A quick “quiz” on what not to do…1 . When were George and Tony in Donlon?2 . What did the ditty strezzle do to George’s grep?3 . What kind of saples did George and Tony pepper?4 . What was Tony’s reaction?5 . What do you imagine happened next?6 . Based on the incidents in this story, do you think George and Tony will want to return to Donlon? Why or why not?Physics 207: Lecture 1, Pg 10A quick “quiz” on what not to do…1 . When were George and Tony in Donlon?Fernday2 . What did the ditty strezzle do to George’s grep?Boofed3 .
