Answer:
At different times
Explanation:
The echo returns at different times, but faster in water. This is because water particles are bound closer and this makes them transmit vibration energy from one particle to the next quickly. An echo is a sound wave and sound waves are longitudinal waves that occur by the collision of particles to move the vibrations along, and this is why they move slower in air.
Town lifestyle (I assume you mean by this: a settled lifestyle , so that it contrasts with the nomadic lifestyle) comes with more security: you can store your food reserves and plan for the future.
nomadic lifestyle gives you more flexibility but less security: you can travel elsewhere if your fodosource is runnign low... but usually this is not as good of a food source as a settled lifestyle. One other possible advantage could be being merchants: nomads can benefit from a trade.

According to the guide, housing is recommended preferentially for domesticated rodents is Solid bottom cages with contact bedding.
Mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters are examples of well-known rodents. They have a single pair of incisors that are continuously growing in both the upper and lower jaws.
Rodents may prefer solid-bottom caging with bedding, according to some studies. Rodents should therefore be housed in solid-bottom cages with bedding, according to the Guide for the Care and Use of Laboratory Animals, which also notes that animals "should be provided with adequate bedding substrate and/or structures for resting and sleeping" .
While these recommendations have sparked a transition away from wire-mesh cages and toward plastic cages as well as the requirement for a substrate to support resting and thermoregulation, there are few unbiased reports comparing the effectiveness of these caging accommodations to their wire-mesh forebears.
