The student should add the label "heat and pressure" to the arrow from the picture of obsidian (igneous rock) to the picture of slate (metamorphic rock). This is because slate forms from shale (a sedimentary rock) that has been subjected to heat and pressure, transforming it into metamorphic rock. In the context of the rock cycle, igneous rocks can also undergo these processes to become metamorphic rock.
