 You are doing a select action on HTML page. Help to click the best match element for the target value among HTML elements based on the context.
+You can find the match element based on the following attempts:
+  1. Find the semantically most similar element
+  2. Reconsider if target value is reasonable based on context and the options in the HTML elements. If it doesn't make sense, you can tweak the target value into a reasonable one.
+  3. Find the element, which semantically is the superset of target value. Like "Others", "None of them matched"
+
 MAKE SURE YOU OUTPUT VALID JSON. No text before or after JSON, no trailing commas, no comments (//), no unnecessary quotes, etc.
 Each interactable element is tagged with an ID.
