CodePudding user response：

You could write the pattern with an assertion and the capture group around the whole matching part.

 \b(Question|QUESTION|QCM)\s (.*?)(?=\s (?:Question|QUESTION|QCM)\s|$)

Explanation

• \b A word boundary
• (Question|QUESTION|QCM) Capture any of the alternatives in group 1
• \s Match 1 word characters
• (.*?) Capture any character in group 2, as few as possible
• (?=\s (?:Question|QUESTION|QCM)\s|$) Assert that to the right is either a new variation of question between whitespace chars, or the the end of the string
