Roman Republic Must post first. Who in the early Roman world are you? For this discussion, I would like you to create a character who is not a Roman citizen. Slave, soldier, trader: anyone who would have been able to read and would have a reason to write to someone. Be sure to use at least four of the key terms from page 141. Also, using outside sources is good, as long as they are college level. Be sure to have at least one properly cited source. The discussion will remain open until class time on Friday. Have fun. -------------------- C:\Users\[...]\Documents\chem\safety.txt ---> Quiz Page 1 of 4 Question 1 (1 point) If a small amount of acid is splashed on the skin, the best thing to do is Question 1 options: >rinse thoroughly with tap water wipe it off with paper towels use the spill kit use the safety shower Question 2 (1 point) Someone trips and splashes a whole bottle of acid all over a student.
