Condense the sentence

The sentence in the green box is wordy and poorly constructed. Your goal is to improve each sentence without changing its meaning. You may omit words and/or substitute words. If you'd like to see how I've rewritten them, click the “How Chris might do it” button. Feel free to send in wordy sentences with examples of how you’ve revised them and I will gladly post them for others to see. Don’t forget to tell me your first name or screen name and age.
