Footprints Without Feet โ€” 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.

Griffin had carry out experiment after experiment to prove that the human body could become invisible.
Show Answer & Explanation
Errorcarry
Correctioncarried
RulePast Perfect โ€” had + past participle
Explanation

'Had' is the auxiliary verb for past perfect. It must be followed by the past participle (V3). 'Carry' is the base form. The past participle of 'carry' is 'carried' (regular: carry โ†’ carried โ†’ carried). So: 'had carried out'. Using 'had carry' is a common error โ€” the student recognises the past perfect structure but puts the wrong verb form after 'had'.

NCERT original: Griffin, the scientist, had carried out experiment after experiment to prove that the human body could become invisible.

Exercise 2Gap Filling

Choose the option that best fills the blank in the sentence below.

The two boys were amazed to see fresh muddy imprints of a pair of _____ feet.
A.bare
B.big
C.wet
D.muddy
Show Answer & Explanation
Answerbare
RuleReading Comprehension โ€” Chapter Detail
Explanation

The NCERT opening describes 'the fresh muddy imprints of a pair of bare feet' โ€” Griffin's footprints were visible because his feet were muddy even though his body was invisible. 'Bare' (unshod, without shoes) is the key word โ€” the mystery is footprints with no visible person. 'Big', 'wet', and 'muddy' are distractors; 'bare' is the precise NCERT word.
