Long Answer Questions

Q1: How does Anand’s burglar alarm cause trouble, and what does this show about his inventions?
Ans: Anand’s burglar alarm creates a problem when it mistakenly drops a bag of water on his father, thinking he’s a thief. This leaves his father drenched and angry. The incident shows that the alarm has a major flaw—it can’t tell the difference between a family member and a real intruder. It also shows that while Anand is full of creative ideas, his inventions don’t always work well because he overlooks important details. His excitement for inventing is clear, but he sometimes forgets to make sure his gadgets are practical and reliable.

Q2: Describe how Anand and Anita react when Boppa breaks into their house.
Ans: When Anita hears strange noises, she wakes up Anand, and they find Boppa breaking in. Anita gets scared when she sees Boppa, a rough sweeper, holding a stick and demanding to know where their father’s room is. Anand quickly thinks of a smart plan and points Boppa to his own room with the time machine instead of their father’s, possibly to trick or distract him. Anita and Anand’s actions show they are both scared but also quick-thinking—Anita warns her brother, and Anand uses his invention to try to protect their home during this scary moment.

Q3: Explain the mysterious events surrounding the time machine during the burglary.
Ans: During the burglary, after Anand sends Boppa into his room with the time machine, strange things start happening. Crashing noises, a humming sound, and other odd noises come from the room, making it seem like the machine is working. When the neighbours come, they find only Boppa’s green scarf on the floor—he’s nowhere to be seen—and the time machine is still quietly humming. This is mysterious because no one knows where Boppa went. While the adults think he ran away, Anand believes the machine sent him back in time. The weird sounds and Boppa’s sudden disappearance make the machine seem even more mysterious.

Q4: What is the moral of the story, and how does Anand’s character reflect it?
Ans: The moral of the story is that creativity and imagination are important, even if they sometimes lead to mistakes, because they can help solve problems in unexpected ways. Anand shows this through his constant inventing. Even when things go wrong—like his burglar alarm soaking his father—he doesn’t give up. His time machine, which no one believed would work, might have actually helped stop the thief, showing his cleverness. Anand’s love for building gadgets and his ability to bounce back after failures teach us that being creative and not giving up are valuable traits, even if the results aren’t perfect.

Q5: Discuss how the story uses humour to highlight Anand’s inventive spirit.
Ans: The story uses humour to show Anand’s love for inventing, especially through the funny problems his gadgets cause. His burglar alarm, which soaks his own father instead of a thief, is amusing because it shows how his invention backfires in a silly way. The messy room full of wires and blinking lights for the time machine creates a comical picture of how serious Anand is, even when things seem unrealistic. The funniest part is when Boppa disappears and Anand proudly claims the machine worked, even though no one is sure. These moments make readers laugh while also showing Anand’s creativity, enthusiasm, and belief in his ideas, even when they don’t go perfectly.
