問題文

On the ports tab of an object that fetches one matching row when a call reaches it from inside another object, single letters mark what each port is for. The developer has to say which letter marks the one field handed back to the caller. In the same load, a row-level error mark is expected to show up in the log, and the team has to say at which grade of logging it actually turns up. Which pairing is right?
