 ### Usage:
 
-* Predictions should be a list of K lists, each containing a single string with the solution instructions.
-* References should be a list containing a single string with the ground truth answer.
+* Predictions should be a list of K items, each containing a single string with the solution instructions.
+* References should be a single string with the ground truth answer.
 
 ### Example:
 
 ```python
 predictions = [
-    ["Draw a line AB\n Draw a circle with center A and radius AB"],
-    ["Draw a line BA\n Draw a circle with center B and radius BA"],
+    "Draw a line AB\n Draw a circle with center A and radius AB",
+    "Draw a line BA\n Draw a circle with center B and radius BA",
     ...
 ]  # These refer to K different generations trying to solve the same geometric problem
 
-references = [
-    "Draw a line AB\nDraw a circle with arbitrary radius intersecting AB at C"
-]
+references = "Draw a line AB\nDraw a circle with arbitrary radius intersecting AB at C"
+
 ```
 
 ### Results will be a dict containing the following keys
