The Hohokams built canals for all of the following EXCEPT for transportation. Here's why:
1. **Crop irrigation**: One of the primary reasons the Hohokam people constructed canals was to divert water from rivers to irrigate their crops in the arid desert environment where they lived. This allowed them to grow various crops successfully.
2. **Washing**: The canals built by the Hohokams were also used for washing purposes. They used the water in the canals for cleaning and washing activities, which were essential for their daily lives and hygiene.
3. **Drinking**: While the Hohokam canals provided water for irrigation and washing, they were not used for drinking purposes. The water in the canals might not have been suitable for drinking due to potential contamination from various sources.
Therefore, the correct answer is that the Hohokams did not build canals for transportation. The primary functions of their canals were irrigation, washing, and possibly some ceremonial or symbolic purposes, but not for transportation.
