GRANT: Okay—a bit like a treasure hunt to start with. CLARE: Yes, and then they get their photo taken stepping through the portal. GRANT: And they'll have to write down their details—you know, name, phone number, email...No, hang on... let's keep it simple—just name and email address should do. CLARE: Then after, say, the thirtieth of July, people can visit the university Face book page and vote for their favorite photo. GRANT: So the photo with the most votes wins. CLARE: Yes, I think that should generate quite a bit of interest. GRANT: What about a cut-off date? CLARE: Of course...maybe, uh...the most popular photo as of 5 pm on the tenth of August will collect the pad. GRANT: And the winner will be notified by email. CLARE: And...the winning photo will be enlarged and published in full color on the university Face book page. Label the flow chart below. Write NO MORE THAN TWO WORDS AND/OR A NUMBER for each answer.
