 # 📝 Dataset
   ## Data Description
 
-  Each data point in our dataset is represented as a dictionary with the following keys:
+  The dataset comprises two parts, the txt book and the json QA tuples. Each json file has a corresponding txt file with the same filename (as the novel title). 
+  Each json file comprises a `list` of `dict`s, where a `dict` has a basic structure as follows.
 ```
+[
     {
-        "Question": The input question,
-        "Options": [
-            Option A,
-            Option B,
-            Option C,
-            Option D
-        ],
-        "Complex": "mh",
-        "Aspect": "times"
-    }
+        "QID": the QID which remains unchanged for tracking updates (only happen if necessary),
+        "Aspect": the question classification in 'aspect', e.g., "times",
+        "Complexity": the question classification in complexity, e.g., "mh",
+        "Question": the input question,

 Currently we are only open-sourcing the fields above, without including the `Evidences` field in the case of answer leaking. However, individuals in need of the `Evidences` field for analysis can contact us (see [📮 Contact](#-contact)) to obtain it.
