Question

When I was a child, there used to be a fair in my town during the Diwali and Id festivities. Among the many things I saw was a strange puppet show. There were three puppets, one of a man, another of a woman, and the third one of a rakshasa (demon). Whenever the rakshasa was brought close to the woman, she would turn her face away. But when the man was brought close to her, she would turn back and face the man.

• (A) The strange behaviour of the woman puppet was:
  1. definitely because someone was moving it with sticks or strings.
  2. definitely because there were magnets fixed in the heads of all three puppets.
  3. could be because of magnets in the heads of all three puppets or someone moving them
  with sticks or strings.
  4. just a random thing. Since we were children then, we thought it was happening in a
  particular way.
• (B) If there were magnets fixed in the heads of the puppets inside the head such that one end
  of the magnet was at the mouth (M) and the other at the back of the head (B), then the
  arrangement of the north (N) and south (S) poles of the magnets must be like:
  1. man: M-N, B-S; woman: M-N, B-S; demon: M-N, B-S
  2. man: M-N, B-S; woman: M-S, B-N; demon: M-S, B-N
  3. man: M-S, B-N; woman: M-S, B-N; demon: M-S, B-N
  4. man: M-S, B-N; woman: M-N, B-S; demon: M-S, B-N
  directions.
• (C) One of my friends stayed back one day at the show and kept looking at the puppets for a
  long time. He asked the manager of the show to move the puppets in certain ways. The 3 manager as a kind person and with my friend's insisting, he agreed to do what my friend asked
  for. But he did not tell the friend if there were magnets in the puppets. But the next day, the
  friend told us that he was sure that there were magnets inside the puppets’ faces. What did he
  ask the manager to do and what could he have seen? He must have seen the effect after
  asking for moving the puppets:
  1. backwards towards each other.
  2. at different speeds.
  3. up and down.
  4. On the same plane, but in different directions.

Hint:

When testing for magnets in puppets, try manipulating them in ways that would expose magnetic fields, such as moving them towards each other or rotating them.

Answer 1

The Correct Option is A

The strange behaviour of the woman puppet could have been due to the use of magnets, which interact based on polarity. Moving the puppets in specific ways would have shown that the interaction between the magnets was the cause of the movement. The north and south poles of the magnets would align such that when brought near each other, the movement was determined by the magnetic interaction.
