Questions 1 through 4 relate to the following ER diagram. The following ER diagram represents two entities and a relationship between them. Assume that we want to redraw the ER diagram above using an associative entity. We come up with the following partial solution, with circled numbers in the diagram indicating the incomplete parts. Each number is referred to in a question with the same question number. Please refer to these numbers to answer the questions. What should be the cardinality notation here?
