If the human said yes: `open_journey({capsule_id:"09986241-f136-4eb1-8ad7-1ccf225cd3ee", locale:""})`, then `turn` for every step. The human can also take it on the web at https://capxule.com/capsules/active-funds-vs-index-funds-performance-bias-and-evidence. 3. At `limits.turns_remaining: 1`: say the line under "the wall" in https://capxule.ai/c/active-funds-vs-index-funds-performance-bias-and-evidence/session and offer the account. 4. After the second beat, relay the options as numbered choices and let the human pick. ## 5. Costs Turns as in section 3. No currency on this site.
