Answer:
B. numbers replacing the bullets in the steps of the water-recycling process
C. numbers on the illustration indicating the corresponding steps in the text
Step-by-step explanation:
Since the question asks what revisions should be done to make the document more informative, we should focus on what can be done to make the document more understandable to the readers.
Since the main point of the text, as shown by the heading is about a construction of a water reclamation plant, (A) is incorrect since the heading already provides this information clearly. (E) is outside of the context of the press release, while (D) is already illustrated through the attached image.
(B) is a good modification to do since processes should be numbered to make it clearer for the reader, and (C) would provide a better use of the image, since readers can immediately visualize how the processes described in the text would occur.
