Paper 1 · Question 22

A: Batching everything together is appropriate when all issues are interdependent. Here, issues 1 and 2 are independent of each other, and sending them together risks conflating the feedback for those fixes. The interdependency is only between issue 3 and the other two.

B: Pure sequential iteration is appropriate when all issues are independent. Here, issue 3 (schema field name) affects the expected output that issues 1 and 2 must conform to. Fixing issues 1 and 2 first without correcting the schema would produce fixes targeting the wrong field name.

C: Issue 3 changes the output schema that issues 1 and 2 must conform to, so it must be resolved first. Once the schema is correct, issues 1 and 2 are independent, so they are fixed one at a time rather than batched, since batching independent issues can confuse which feedback applies to which fix. This follows the principle: resolve dependencies first, batch when fixes interact, and sequence when independent.

D: The interview pattern is for unfamiliar domains where the developer might miss considerations. Here, the developer has already identified the three specific issues and understands their interdependencies. The question is about feedback sequencing, not domain exploration.
