This assignment is worded very strangely, but keep in mind there is a total of 18 paragraphs. Try to keep the paragraphs limited to what is required. This is a lengthy assignment and usually is 3 – 4 pages in length. The tricky part that stumps most students is the strange way the directions are written. But you must adhere to the policy or points are counted off.

1. Write a one-paragraph INTRODUCTION that addresses both Dry Cleaning and Fracking

2. Write a five (5) paragraphs article review (not 2, not 6; but 5) on the Sinshelmer, et al article about dry cleaning.

3. Write a five (5) paragraphs article review (TOTAL of 5, not five each, not 3 and 2; but 5) on the Heywood and Chen et al articles about fracking and discuss the use of liquid Carbon Dioxide alternative. All this in a TOTAL of five paragraphs.

4. Write a five (5) paragraphs article review (not 2, not 6; but 5) on the Taylor et al article on the use of Carbon Dioxide as an alternative source in dry cleaning and fracking.

5. Last, write a two-paragraph summary (Conclusion) about P2 alternatives to dry cleaning and fracking.

There is no need to make your paper longer; it will not improve your score.
