Answer:
As an alternative ending, we can say that the remarkable rocket was not presumptuous and had a good relationship with the other rockets. However, it ended up falling out of the rocket basket, into a puddle of water and therefore could not be lit. Then it was put to dry and when it was ready to be used, it made a show of colors that left the Russian princess extremely surprised and delighted by the remarkable rocket's ability.
Step-by-step explanation:
An alternative ending is a different ending than the official ending of a story. At the real end of "Remarkable rocket", the rocket is discarded, after having gotten wet with its own tears at a time when it was being smug and put on. It was not put to dry, but thrown away. It was accidentally used by boys looking for sticks to light a fire. These kids lit the rocket at noon and it really blew up, but nobody saw it.
