Note that it is asking for conservation and management of water:
Use technology to produce clean water. If technology can be used to create more clean water without losing natural resources, by all means use technology for it.
Use water wisely at home and in industry. This is the definition of conserving water and managing usage of water.
Use techniques and tools to reduce water loss. This is the pathway to conserving water.
Those that are in a grey area:
Take care of living things that live in water. This should occur, and it is managing the water condition, but as for conserving water, that is a different story.
Encourage recreational activities year-round. Recreational activities usually do not have to do with water in a major way, but year-round is a bit too much. Of course, if all these recreational activities use large amounts of water, then it will end up in the "not" section.
Those that are not:
Stop using water in all areas of life. You will need to drink water first off, and a human cannot survive for longer than 3 days without water. You also need water to help you stay clean, as well as other tasks.
Your definite correct answers are the first 3 listed, and the 2 after is up to how you view if it is both managing as well as conserving water.
