Final answer:
The transition 'However' should be added to the beginning of sentence 7 to enhance the organization of the paragraph.
Step-by-step explanation:
To enhance the organization of the paragraph, the transition 'However' should be added to the beginning of sentence 7.
This transition introduces a contrast or contradiction to the previous information, indicating that the following sentence will present an opposing point of view or unexpected information. It helps to transition smoothly to a different perspective or idea.
For example, Sentence 6 might state a positive outcome, and adding 'However' at the beginning of Sentence 7 allows the writer to introduce a different viewpoint or present a counterargument, improving the overall organization of the paragraph.
