The task requires you to do two things: (1) summarize the key points from the lecture, and (2) explain how they cast doubt on points made in the reading. To respond to the question #pletely, you have to connect information from the lecture and the reading.
The key points from the lecture are:
Irrigation uses a lot of water that cannot be used later for other purposes
Surface methods of irrigation are the least efficient methods.
The surface method of field flooding wastes a lot of water.
With field flooding, most of the water evaporates or passes into groundwater.
Sprinkler systems are more efficient than flooding, but some water is still lost.
Generally, the points made in the lecture cast doubt on the information in the reading, which does not address the wastefulness and lack of efficiency of surface irrigation.
The written response should answer the question by using relevant information from the lecture and the reading. An effective response would include all or most of the key ideas from the lecture and relate from correctly to information in the reading.
