問題文

選択肢
- A command that declares its arguments and replies, so the person building the workflow can wire earlier values into it and use its result afterwards.
- A step that declares its inputs and outputs, so the person running the workflow can type fresh values into it and read its result immediately.
- A step that declares its own inputs and outputs, so the person building the workflow can wire the earlier values into it and use its result afterwards.
- A shortcut that declares its context and payloads, so the person building the workflow can wire earlier values into it and use its result later.
