BALS Concentration/GE Questions

[PLEX]

I see BALS requires either:

• Option A: 42 credits of Liberal Studies courses that include at least 15 credits at the 3000/4000 level and no more than 6 credits at the 1000 level.
  

-OR

• Option B: Select an 18-credit concentration and complete an additional 24 credits of Liberal Studies courses.
  

Questions:

• I'm going to guess option B still has the same level requirements, overall, as option A, but I haven't found mention of level requirements specifically within the Concentration's 18 credits. Anyone know if that is specified?
  
• Next, I'm wondering if I can use some credits for the concentration and to also cover general ed?
  
• Lastly, just within GE, can one class be used for more than one GE requirement - while counting extra credits in another area to make up the total 45 required GE credits? 
  

More info: I'm working to gather up all my info to get degree plan options pinned down, but also having my own preliminary look around and wondered about the above. In short: in my 78 existing credits (47 RA), I'm hoping TESU would accept my communications credits that mostly don't map directly to their classes, but include 14 RA at 300-400 (Persuasive Speech, Research in Debate, Rhetoric of Feminist Movement, Women and Words) 11 RA at 200 (Forensics = competitive debate & speech 4 X 2cr, Debate and Argument), and more at 100 (RA Fund of Oral Comm, ACE Visual Comm, etc.). Some of the mid and upper seem fit for GE areas, as well as for concentration.

Thanks!
