Nuclear reactions provide us with enormous amounts of energy.

Currently, there is no feasible way to harness this energy from fusion and use it to power our infrastructure, but several years down the road, it is possible that it could supply us with the energy we need.

In a way, we are able to use some of the energy from fusion reactions.

In many disciplines, multiple-choice tests have been developed to gauge student prior knowledge and assess learning.

Effective instruction hinges in part on understanding what prior knowledge students bring to the classroom, and on evaluating how this knowledge changes during instruction.
