Final answer:
The sentence that requires a transitional phrase to improve flow is 'Sprinter's shoes organized a charity fun run last fall. The fun run raised $25,000 for the construction of a community running path,' where a transition like 'Consequently' would clarify the relationship between the event and its outcome.
Step-by-step explanation:
The example that needs a transition word or phrase between sentences to connect the ideas is: sprinter's shoes organized a charity fun run last fall. The fun run raised $25,000 for the construction of a community running path. A suitable transition would clarify the cause-and-effect relationship between the two sentences. For instance, adding 'Consequently,' or 'As a result,' at the beginning of the second sentence will improve the flow of the paragraph and help readers understand that the fun run was successful in raising funds.
Using transitional words and phrases is vital in writing to bridge ideas, showing how they connect or are opposed to each other. Transitions also help guide readers between paragraphs and make the writing structure more coherent and easier to follow.
