We provide the BCOPA-CE test set, which has balanced token distribution in the correct and wrong alternatives and increases the difficulty of being aware of cause and effect. ### construction 1. for each premise of the 500 samples in COPA-test set, we generate one event manually which is a plausible answer to the opposite question type of the original sample. 2. obtain 500 triplets of <*premise*, *cause*, *effect*> 3. construct 1000 samples by giving two different questions (cause or effect) to each triplet.
