Answer

Brief Explanations:

The text states that New Shepard is a reusable spaceship which addresses the non - reusability of traditional spacecraft. And the BE - 4 engine runs on methane which is less likely to clog engine fuel lines, solving the clogging problem of traditional engines.

Answer:

Traditional spacecraft cannot be reused: Blue Origin launched New Shepard. Traditional engines can get clogged: Blue Origin developed the BE - 4.
