Question

(a) a noble encyclopedia
(b) a tome about rockets
(c) Mother Goose
(d) a secret file

Answer 1

Mother Goose is the correct answer to this question.

Answer 2

Mother Goose stopped the Martian invasion of 2040. The Marian invasion is mentioned in a play The Book that Saved the Earth. The Martians are inhabitants of Mars who plan to invade Earth and take control over the Earthlings.  

The Martians enter a library and get hold of a book of nursery rhymes called Mother Goose. One of the Martians, Think-Tank reads the rhymes and thinks it is a threat to Mars and its people. This makes him inform all Martians and call off the invasion.
