Ethan, my take on your paragraph can be found below composed of 71 words. This paragraph is a bit complicated to paraphrase in only 75 words due to the numerous important information involved. So you have to learn how to combine the information into a continuous thought pattern such as the one I developed below. This takes lots of practice and even then, is a bit difficult to do because of the exam time constraints involved. So to complete this in the actual scenario, you need to be able to relax yourself and actually allow yourself time to think rather than panic and keep watching the clock. That is how you will fail this part of the test. Just breathe, relax, analyze, take notes, and write. Try to keep a clear head at all times.
