1. What is Non-null ? Junior A. the rule that when a non-null field resolves to nothing or errors, the failure bubbles up to the nearest nullable ancestor B. the top-level response key listing problems encountered, returned alongside any partial data that did succeed C. the schema modifier, written with a trailing exclamation mark, guaranteeing a field or argument can never be the absence-of-value D. the open-ended response map carrying non-standard metadata, such as error codes or tracing, outside data and errors
2. Which term means: "the schema modifier, written with a trailing exclamation mark, guaranteeing a field or argument can never be the absence-of-value"? Junior A. Errors-as-data B. Null propagation C. Partial response D. Non-null
3. Which statement is correct? Junior A. Non-null — the open-ended response map carrying non-standard metadata, such as error codes or tracing, outside data and errors B.
