The Book That Saved the Earth — Grammar Exercises
Two grammar exercises based on real NCERT sentences from this chapter. Practise the editing and gap-filling formats tested in CBSE Section B.
Exercise 1Editing / Error Correction
The sentence below has one grammatical error. Find the incorrect word and write the correction.
Show Answer & Explanation
The play is set in the 'past' of the future — the Historian narrates events that (in the play's fiction) have already happened. All narrative verbs are in the past tense. 'Order' is the present/base form. The simple past of 'order' is 'ordered' (regular: add '-ed'). 'Ordered' is the correct past tense form here.
Exercise 2Gap Filling
Choose the option that best fills the blank in the sentence below.
Show Answer & Explanation
Think-Tank's line is 'Mirror, mirror, in my hand, who is the most fantastically intellectually gifted being in the land?' — a parody of the fairy tale 'Snow White'. The NCERT text has 'hand', not 'eye', 'mind', or 'heart'. This detail is significant because Think-Tank carries a mirror as a symbol of his vanity. The exact word 'hand' is from the verified NCERT text.
