Washington State is experiencing a water shortage, and Iowa has extremely high precipitation in the form of rain and snow. Match the technologies with the states that can use them to reduce the impact of natural disasters.

Given that the Washington State has a serious problem of lack of water, while Iowa has the opposite problem, a balance should be sought to redistribute this proportion of water between the states.

The most viable and appropriate option to resolve this situation would be to build a dam on the Mississippi River, which forms the eastern border of the state and collects the largest amounts of rainwater in its flow.

Then, this dam should be connected through channels and aqueducts with the other Iowa rivers, such as the Cedar River, until reaching the Missouri River, the river that marks the eastern border of the state.

There, the course of the aqueducts should be piped so that they run underground to the west, supplying not only the Washington State, but all the states that in the course of the pipeline have aridity problems, through different extraction and pumping points.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
