emma had to borrow a pair of jeans from katie because she spilled cranberry juice everywhere.

Explanation:

The pronoun "she" is vague here as it could refer to either Emma (the one borrowing jeans) or Katie (the one lending jeans). We analyze the context: Emma needed to borrow jeans, possibly because Emma (she) spilled juice, or maybe Katie (she) spilled juice leading to Emma needing to borrow. So both Emma and Katie are possible antecedents.

Answer:
