Was Grandfather aware that Ravi was following him? How do you know?
Yes, Grandfather was fully aware that Ravi was following him.
We know this from Grandpa's remarks and actions after the incident. When Ravi's mother asked what they did, Grandpa coolly replied that he didn't know about Ravi, who "just disappeared instead of staying at home to look after me." This clever response shows he knew Ravi had secretly trailed him.
Furthermore, Grandpa gave Ravi a detective story book as a gift, which directly hints at his awareness of Ravi's detective-like behaviour. Grandpa also made a pointed remark about "how to avoid getting fooled when one is trailing a suspect," and Ravi noticed a twinkle in Grandpa's eye, wondering if it was an innocent gleam or a mischievous one, confirming Grandfa was playing along all along.
Explanation
The question tests whether students can infer Grandfather's awareness from his dialogue and actions. The context provides clear evidence: Grandpa's cool remark to the mother about Ravi 'disappearing', his gift of a detective story book, his comment about 'trailing a suspect', and the mischievous twinkle in his eye all point to him knowing Ravi was following him.
Solution Steps
Step 1: Identify Grandpa's awareness from his dialogue to the mother where he mentions Ravi 'disappeared'
Step 2: Note the significance of the detective story book gift
Step 3: Connect Grandpa's remark about 'trailing a suspect' and the 'twinkle in his eye' as final proof of his awareness
