 - `cluster`: An integer identifier for the cluster that the instance belongs to. <!-- The dataset is split into 'train', 'validation', and 'test' such that all instances from the same cluster belong to the same split. This is to ensure that there is no intersection of paraphrased questions across different splits. If you plan to create a new split of the dataset, it is important to maintain this clustering to avoid data leakage between splits. -->
