Step-by-step explanation:
The purposes of the underlined feature in the procedural text on how to make pour-over coffee are to draw the reader’s attention to the steps of the procedure and to help separate the steps and the measurement information. Highlighting steps ensures that readers can easily follow the coffee-making process, whereas separating the measurements provides clarity on the quantities of ingredients needed, which in this context, involves measuring both the water and coffee. Measurements are essential in recipes to ensure the correct ratios are used for the desired results, much like when doctors measure vital signs to assess health conditions.
