a) The Book That Saved The Earth Summary 

This story by Claire Boiko is a humorous science fiction narrative set in a future time. The story is about a teacher, Miss Frampton, and her students who are studying Earth's history. The plot takes place in a future world where Earth is under threat from an alien species called the 'Zorastrians.' These creatures, in their bid to conquer Earth, have come across an ancient book that they believe holds dangerous powers. The book is none other than a simple English text, The Book That Saved the Earth.

The students, under the guidance of their teacher, are learning about how different historical events and cultural artefacts shaped the present world. As the Zoroastrians try to destroy Earth, they accidentally misinterpret the book, considering it a weapon due to its title. Their confusion and misunderstanding lead to a series of events that ultimately prevent the aliens from succeeding in their mission.

At the end of the story, the aliens retreat, realizing the book holds no power over them. This teaches a valuable lesson about how perceptions can differ and how an object or concept can be interpreted in many ways, even if it is benign or harmless in reality.

b) Key Incidents that happened in the story:

Abandoning the Invasion Plan

  • Earth is saved, unknowingly, by a simple children’s book.
