Including Keffer's memory helps achieve the author's purpose because the author's purpose is to inform, and this informs the reader about pedestrians, and what they should do! It's important to know what Keffer remembered because it helps achieve the authors' purpose, and adds on to more information mentioned earlier in the text. It also gives us Keffer's point of view!
I think the correct answer would be the third option. Using an implied main idea would not be a good strategy for writing a supporting sentence. These sentences should contain substance or evidences that would support the main idea of what you are writing. Using implied ideas would be very vague for the readers making the readers doubt on what message you are conveying. Supporting sentences should be straight to the point and be very specific and should provide a good foundation for the main idea. Using facts, examples and statistics that are verified by reliable people are very good strategies in writing supporting sentences.
