Show answer
(Content 2 – any two points; Expression 1) Noodle flatters Think-Tank to protect his ego and appears to agree with him respectfully.

Show answer
(Content 3 – any three points supported by textual evidence; Expression 2; Accuracy 1) The Martians had spaceships and advanced technology, yet they were terrified by a book of nursery rhymes. Their leader, Think-Tank, believed himself the most brilliant being in the universe, but his arrogance hid a lack of real understanding.

Think-Tank decoded ‘Mother Goose’ as a secret code: he read ‘Hey Diddle Diddle’ as an Earth plan to reach the moon and ‘Humpty Dumpty’ as a threat to his own egg-shaped head.

Show answer
(Content 3 – any three points supported by textual evidence; Expression 2; Accuracy 1) The Martians, led by the arrogant Think-Tank, planned to invade Earth but understood nothing of its culture. Their interpretations of earthly things were strange and funny: Think-Tank took the library for a barn and then a haberdashery, and decided that books were sandwiches, ordering Omega to eat one, who found it very dry. When they examined ‘Mother Goose’, he read the innocent nursery rhymes literally, lacking any sense of human culture or humour. ‘Mistress Mary, quite contrary’ seemed an Earth plan of weapons and spies, ‘Hey Diddle Diddle’ suggested Earthlings could reach the moon with animals, and …
