- The families of the dead scientists
- Correct answer: A man who leaps onto the platform

Question 4. In the line "Now, fettered to the very machine he had planned and constructed," what does fettered mean?
- Correct answer: Chained or held fast
- Praised as its creator
- Blamed in public for it
- Kept away from it by law
Fettered means chained or bound so that a person cannot move freely. Layeville is welded inside the pendulum of his own machine and cannot get out.

Question 5. At the trial, what do the jeering throngs first cry out for?
- Layeville exiled from the city forever
- A full inquiry into what went wrong
- Layeville forced to repair his machine
- Correct answer: The machine and its inventor both destroyed
The crowd shouts, "Destroy the Time Machine!" and "And destroy this MURDERER with it!" Nobody asks for an explanation; the story shows mob justice, a crowd hungry for revenge rather than understanding.

Question 7. Who looks after Layeville once the humans decide he is not worth the bother?
- The schoolchildren who ride the moving sidewalk
- Correct answer: Robots that bring food, clean the cell and oil the machine
- Prison guards whom the tribunal sends every morning
- Tourists who pay to drop food parcels down the tube
"The robots took care of him now. Evidently the humans thot it a waste of time to bother over their prisoner." The robots bring food, clean the cell and oil the machinery, and they keep at it for a thousand years.

Question 8. In the line "Continuous, monotonous movements over and above the ground," what does monotonous mean?
- Correct answer: Dull, repeating without change
- Graceful and lovely to watch
- Sudden and hard to predict
- Wildly fast and out of control
Monotonous means dull because it never varies. The swing goes up and down, back and forth, the same way every time, and the sameness is part of Layeville's torment.

Question 9. What destroys the people of the city while Layeville swings?
- A blast of fire from the rebuilt time machine
- Correct answer: Black gelatinous masses that suck out life
- A fleet of rocket ships from a rival city
- Robots that rise up and turn on their makers
"Alien creatures fluttered down, great gelatinous masses of black that sucked out the life of all." An hour later they were gone, and the city was dead.

Question 10. Why does Layeville feel elation after the alien attack?
- He thinks the attack proves his theory
- He thinks the robots will now let him go
- Correct answer: His prison has shielded him from death
- He hopes the creatures will free him
"Where the other men had planned the pendulum as a prison it had been an asylum against annihilation now!" The punishment meant to torment him is what kept him alive.

Question 11. How long does the pendulum swing before the visitors stop it?
- About one week
- About one century
- About ten years
- Correct answer: About a thousand years
"A thousand years this pendulum had swung." The robots kept it going long after every human was dead.

Question 12. In the line "it had been an asylum against annihilation now," what does asylum mean?
- Correct answer: A safe shelter from danger
- A trap that holds a captive
- A sentence for a grave crime
- A hospital for the mentally ill
Here asylum means a place of safety or protection. The pendulum, built as a prison, became the shelter that saved Layeville from the creatures that killed everyone else.

Question 13. Why does Layeville think his title, THE PRISONER OF TIME, is ironic?
- He meant to free people from time and now he must serve it
- Correct answer: His invention became a clock, and he marks out its years
- The judges once praised him as the master of all time
- He was sentenced for a crime that took no time at all
He finds it ironic "that he should invent a time machine and have it converted into a clock, and that he, in its pendulum, should mete out the years." The man who wanted to travel through time now measures it with his own body.

Question 14. The words 'up and down, back and forth' recur all through the story. What does this repetition do?
- It marks each place the story jumps in time
- It repeats the chant of the crowd at the trial
- Correct answer: It imitates the pendulum's ceaseless swinging
- It shows the robots counting the hours
The repeated phrase swings back and forth like the pendulum itself, so the reader feels the same dizzy, endless motion that Layeville does. The story opens and nearly closes with it.

Question 15. The story's title and its central image of a prisoner and a swinging pendulum echo which earlier work?
- Washington Irving's Rip Van Winkle
- Hawthorne's The Minister's Black Veil
- Melville's Bartleby, the Scrivener
- Correct answer: Poe's The Pit and the Pendulum
The title and the pendulum point to Edgar Allan Poe's The Pit and the Pendulum (1842), where a prisoner lies beneath a swinging blade. Bradbury, a lifelong admirer of Poe, puts his prisoner inside the pendulum instead.

Question 16. When the visitors open the cell, what does the skull's grin suggest?
- Correct answer: That Layeville, in the end, had beaten time by outlasting it
- That Layeville had gone insane, just as he had feared
- That Layeville died laughing as the visitors landed
- That the robots had kept Layeville content all along
The skull grins "as if it knew that it had conquered something. Had conquered time." Layeville had indeed "travelled along the centuries," just as he once dreamed, though not in the way he meant.
