The uranium in nuclear reactors comes from supernova explosions.

Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false) and choose the correct explanation.

Answer: this statement makes sense.

Explanation:

Supernova explosion is a bright powerful explosion of the start, it takes place at the end of the cycle of a star. This explosion is caused by having too much matter in it's core, As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in a massive explosion of a supernova. During this explosion Elements heavier than iron are formed. An uranium atom is heavier than an iron atom, so uranium falls into this category of elements that comes from supernova explosion.
