Task: Question Answering
Input (English): passage: Fusion power is a form of power generation in which energy is generated by using nuclear fusion reactions to produce heat for electricity generation. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, and at the same time, they release energy. This is the same process that powers stars like our Sun. Devices designed to harness this energy are known as fusion reactors.
 question: can fusion be used as an energy source?
Output (English): Yes
