It was easy as pie, the hardest part was the 8 marker on biodevices, the rest was cake. The space science option was a walk in the park, but I wasn't completely sure about the voyager probe question as I know nothing about the voyager probe. I just made up stuff about how it photographed the planets of the solar system which helped scientists to study the planets and gain an understanding of how they may have been formed, does anyone know what you were supposed to say?
