To tackle this crisis, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing. After 6.___________ (graduate) in 1953, he worked as a researcher. Yuan Longping realised that larger fields were not the solution. Instead, farmers needed to boost 7.__________ (yield) in the fields they had. How this could be done was a challenging question at the time. Yuan was 8.____________ (convince) that the answer could be found in the creation of hybrid rice.
