Answer:
The use of the abacus was expanded and refined.
Explanation:
The abacus was invented during the Yuan Dynasty which lasted between 1206AD till 1368AD and then it was expanded and refined by the Ming Dynasty (1368AD-1644AD).
There have been archaeological proof of this as the writings of Tao Zongyi describes in his book that the new servants, unlike the older and more experienced ones were "just like abacus heads" and that they would not move unless they were made to move. This bears credence to the fact that the abacus was already widely used then.
An abacus was used to count numbers.

Many people/groups were involved. Anti-war marches and other protests, such as the ones organized by Students for a Democratic Society (SDS), attracted a widening base of support over the next three years, peaking in early 1968 after the successful Tet Offensive by North Vietnamese<span>troops proved that war's end was nowhere in sight. I mean, who wouldn't be mad? There was a draft that forced citizens to fight in a war they didn't even believe in! A war that lasted 19 YEARS and 180 days!
