The Founders Conceived of Congress as "Congressus," a Coming Together

The Founders conceived of Congress as "congressus," a coming together, in contrast with:

B) the Spanish Contendere, based on the root word "contende" (to contest)
C) the Roman Senate, based on the root word "ate" (having eaten)
D) the French Guillotine, based on the root word "guillot" (to cut off)
