The government health service has said that it definitely will not pay for patients to take the influenza medicine Antinfia until the drug's manufacturer, PharmCo, provides detailed information about Antinfia's cost-effectiveness. ███████ ███ █████████ ████ █████████ ████ ███████████ █████ ███████ ███████ ████████ ███████ █████ ██████ ██████ ██ █████████ █████ ███ ████ ██ ██ ██████████ ████████████ █████████ ████ ████ ██████ ████ ██ ███ ██████████ ██████ ███████ ████ ███ █████████
The government will not pay for patients to take Antinfia until the manufacturer provides information about the drug’s cost-effectiveness. This information can only be obtained by performing massive clinical trials. The trials cannot be performed until the drug is in widespread circulation, which will happen only if the government pays for Antinfia.
Government pays → provide detailed info → massive clinical trails → widespread circulation → government pays
This chain is circular, and the stimulus says the government is not paying. You can run the contrapositive back and draw any valid inference along the chain. (no widespread circulation, no clinical trials, no detailed info)
