title: RegEx to Extract Multiple Choice Questions
body: <p>I have 24 exams in a plain text file with 50 MC questions each plus a bunch of other stuff.  Here is an example of what I'm trying to capture:</p>
  
  <p><strong>1 Studying oral histories, archaeological evidence, and cultural histories are methods most often used by 
  (1) 
  economists (3) philosophers 
  (2) 
  anthropologists (4) political scientists</strong> </p>
  
  <p>I'd like to capture the stem and the 4 answer choices for each question, or at the very least, just the stems.  </p>
  
  <p><strong>How do I get it so the regex captures everything from the digit (question number) all the way up to, but not including, the first open parenthesis of the first answer choice?</strong></p>
  
  <p>So far, I have: \d{1,2}\s</p>
