 | **Spatial Relation** | Identify the relative positions of objects |
 | **Trajectory Description** | Summarize the trajectory of moving objects or camera|
 
+### Dataset Fields Explanation
+
+The dataset contains the following fields, each with its respective description:
+
+| Field Name        | Description |
+| :---------------- | :---------- |
+| **Video**         | The string corresponding to the video file. |

+| **Task**          | The string representing the task type, e.g., "3D Video Grounding," "Ego-Centric Orientation," etc. |
+| **QType**         | The string specifying the question type, typically a multiple-choice question. |
+| **Question**      | The string containing the question presented to the model. |
+| **Prompt**        | Additional information that might be helpful for answering the question, such as object descriptions. |
+| **time_start**    | A float64 value indicating the start time of the question in the video (in seconds). |
+| **time_end**      | A float64 value indicating the end time of the question in the video (in seconds). |
+| **Candidates**    | A dictionary containing answer choices in the format `{"A": "value", "B": "value", ...}`. |
+| **Answer**        | The string corresponding to the correct answer, represented by the choice label (e.g., "A", "B", etc.). |
+| **Answer Detail** | A string representing the precise value or description of the correct answer. |
+| **ID**            | A unique integer ID corresponding to the specific video in which the question appears. |
+| **Scene**         | The string describing the scene type of the video, such as "indoor," "outdoor," or "desktop." |
