The correct options are:

1. The canals connected waterways which increased trade: The building of canals in China during the Song and Tang Dynasties played a significant role in promoting trade and economic growth. The canals connected various regions, allowing for the transportation of goods and the expansion of commerce.

2. The canals improved the irrigation system in the rice fields: Canals were used to irrigate the rice fields, improving agricultural production and contributing to food security in China. The transportation of water through canals helped in efficiently distributing water to the fields.

3. The canals were eventually used for military routes: While the primary purpose of the canals was to facilitate trade and agriculture, they also had military significance. Some canals were later used as strategic routes for moving troops during military operations. This allowed for quicker movement of soldiers and resources during times of conflict.

However, the statement "The canals made it easier for neighboring nations to attack China" is not accurate. While the canals provided improved connectivity and transportation, they did not directly facilitate attacks from neighboring nations.
