The question provides a list of students: Emily, Ann, Brian, and Grant. It mentions that their responses about studying on Sunday are shown in a Venn diagram. However, the Venn diagram itself is not provided in the question.
Step 2: Analyze the Given Data
Since the Venn diagram is not provided, we cannot directly determine who studied on Sunday. The question asks for the names of students who studied on Sunday, but without the Venn diagram, this information is unavailable.
Step 3: Conclude Based on Available Information
Given the lack of a Venn diagram, it is impossible to determine which students studied on Sunday. The question cannot be answered without the visual representation of the Venn diagram.
Final Answer
The question cannot be answered without the Venn diagram.
