Do you mean flag on 7Sage or on LSAC's Law Hub? If you mean Law Hub, it is directly right of the questionstem. It is an outline of a flag and then once you click it, it fills in,
It's labeled as an MSS question, though I think it could also be interpreted as an MBT question. Thankfully, either interpretation works here, and this is not a questionstem used on more recent tests.
Very worth, especially for the CLIR. While it doesnt work out on every situation, it definitely gets you open to thinking in different strategies which can help out when I'm frozen/paralyzed while understanding a questionstem.
