The main idea tested here is understanding how the Tet Offensive differed in scale from earlier U.S. operations. Tet was not a few isolated strikes; it was a broad, coordinated campaign in which North Vietnamese and Viet Cong forces attacked across many provinces and several major cities simultaneously, involving multiple divisions. This large, multi-front effort marked a major increase in the scope of fighting and showed that enemy forces could mount sustained operations across the country, despite years of U.S. escalation. In contrast, earlier U.S. actions were more limited in geographic reach and force size, focused on targeted engagements rather than a country-wide, multi-division push. That broader, massed, multi-division nature across the South is why the correct description emphasizes widespread offensives and endurance.
