With no explanation, label A→B with either "reasoning", "contrasting", "entailment" or "neutral".
A: However, we found it difficult for annotators to pinpoint differences between versions where edits modify or provide new information, in contrast to providing only stylistic changes.
B: we designed the task such that annotators had to formulate questions on the presented information whenever possible.

Sure, I'd be happy to help with this task. Here's how I would categorize the sentences:

A: **Entailment**: The first sentence states that the annotators found it difficult to distinguish between certain types of edits. This implies that they did not always find it easy to distinguish between edits that provided new information and those that only introduced stylistic changes. So, A is entailing B since it implies it.

B: **Reasoning**: This sentence presents reasoning. It explains a design choice that was made (presenting information and asking questions whenever possible) based on the observation that it was difficult to pinpoint differences between certain types of edits. So, B is a result of A.

Therefore, A entails B, and B is based on the reasoning that underlies A. And B is neutral towards A.

Reasoning: The statement B explains the measures taken to address the difficulty mentioned in statement A. This indicates a cause-and-effect relationship, where the difficulty in pinpointing differences led to the new task design.
