Class 7 English Poorvi Unit 3 Chapter 1 MCQs with Answer – My Brother’s Great Invention

Anita tells the story using her own experiences and observations. As Anand’s sister, she knows his earlier experiments and the family’s reactions. Her mixture of amusement, doubt and fear shapes the way readers learn about his inventions.

Anita says that she is fourteen and that Anand is one year younger. This makes him thirteen. Their ages help readers understand why the children consider themselves old enough to manage while their parents are away for one night.

Several thefts have occurred in the colony, so Anand decides that a burglar alarm is needed. His invention begins as an attempt to solve a real problem, although its design does not work as safely or accurately as he expects.

Anand designs the alarm to work when the door opens gently, assuming that a thief would enter that way. His father also opens doors softly. The device cannot distinguish him from a burglar, so the water falls on him.

Anand shows an elaborate drawing of doors, wires and bells, which he calls a blueprint. The plan makes him feel professional. It gives Anita a chance to ask how the invention will work and question one of its assumptions.

After watching Back to the Future, Anand decides to make a time machine himself. The film gives a new direction to his inventive enthusiasm. His family expects another noisy period because his projects usually involve taking household gadgets apart.

Anand often dismantles household gadgets to obtain parts for his inventions. His father locks the toolbox, while his mother watches her oven and mixer. Their actions show concern about what his enthusiasm may do to useful things at home.

The story describes a fortnight of frantic activity before Anand announces that his machine is ready. A fortnight means two weeks. During this time, his room becomes crowded with wires, springs, levers, bulbs and a large control panel.

Anand’s mother asks him not to do anything with the time machine until the parents return. He promises reluctantly because he feels his invention deserves respect. The promise adds tension when the machine later becomes involved in an unexpected emergency.

Anita stays awake to finish a novel after Anand falls asleep. The book is a murder story, which makes the strange nighttime sounds even more frightening. She eventually wakes her brother when she believes someone is trying to enter.

Boppa has recently been sweeping the compounds along their row of houses. This work lets him observe when occupants are away. Anita realises that his familiarity with the neighbourhood has helped him choose opportunities to enter empty homes.

Anand deliberately sends Boppa to the wrong room because the delay may give the children time to act. He expects the intruder to struggle with finding the light switch. This quick decision shows presence of mind during danger.

The children recognise Mrs. Sharma’s voice as she arrives with her husband and Dr. Mohan. These neighbours respond to their cries and release them. The scene shows that nearby adults provide help when the children face an unexpected threat.

The green scarf that Boppa wore is found near the panel of switches. It supports the children’s account that he was present. However, this object alone does not explain where he went or prove that he travelled through time.

Anand insists that his invention sent Boppa into the past. The adults consider other possibilities, and nobody confirms what happened. The ending remains mysterious, so a reader must distinguish Anand’s confident belief from an event clearly established by the story.

Papa decides that the time machine is unsafe and has it taken apart. This prevents further testing. As a result, the family cannot check Anand’s claim about the disappearance, and the story keeps its unusual ending open to imagination.

Anand begins a new project involving a telephone to contact creatures in outer space. His confidence remains strong despite earlier difficulties. This ending suggests that his curiosity and desire to invent will continue to create further adventures for the family.

Sceptical means doubtful or not easily convinced. Anita questions whether the alarm can recognise a burglar. Her doubt is reasonable because a family member might open the door in the same way, which is exactly what happens later.

Onomatopoeia uses words that imitate the sounds they describe. Clanging suggests a loud metallic sound, while tick-tock imitates a clock. The story’s sound words help readers imagine both the noisy inventions and the frightening disturbance at night.

Had vanished is in the past perfect and identifies the earlier action. Reappeared describes what happened later. The grammar activity uses this tense relationship to help students place two past events in their correct order without confusing the sequence.
