To accurately respond to your question, I would need to see the specific introductory paragraph in question. However, based on the options provided, here’s how you might determine the technique used:
- If the paragraph includes a story that relates to the main topic, it uses "telling a brief related story."
- If it presents a compelling fact that grabs attention, it uses "telling an interesting or surprising fact."
- If it connects the topic to something the readers commonly experience, it uses "using a connection to the readers’ experiences."
- If it paints a clear and striking picture through words, it uses "using a vivid image or description."
Please provide the introductory paragraph so I can help identify the technique the writer used.
