+### [Dataset Summary](#dataset-summary)
+
+Common Sense Explanations (CoS-E) allows for training language models to
+automatically generate explanations that can be used during training and
+inference in a novel Commonsense Auto-Generated Explanation (CAGE) framework.

+
+- **Size of downloaded dataset files:** 4.10 MB
+- **Size of the generated dataset:** 2.23 MB
+- **Total amount of disk used:** 6.33 MB
+
+An example of 'train' looks as follows.
+```
+{
+    "abstractive_explanation": "this is open-ended",
+    "answer": "b",
+    "choices": ["a", "b", "c"],
+    "extractive_explanation": "this is selected train",

+- `choices`: a `list` of `string` features.
+- `answer`: a `string` feature.
+- `abstractive_explanation`: a `string` feature.
+- `extractive_explanation`: a `string` feature.
+
+#### v1.11
+- `id`: a `string` feature.
+- `question`: a `string` feature.
