Question

Accepted Answer

In H. G. Wells's story 'Footprints Without Feet', the character Griffin is a scientist who is obsessed with the idea of making the human body invisible. This is the central theme of the story and is the reason why Option 3 is the correct answer. Griffin conducts numerous experiments to achieve this goal, ultimately succeeding in making himself invisible. His experiments involve manipulating the refractive index of the human body to match that of air, thereby rendering himself invisible to the naked eye. This scientific endeavor is the primary focus of the narrative and drives the plot forward.

Now, let's examine why the other options are incorrect:

1. **There is life after death**: This option is incorrect because the story does not explore themes of life after death. Griffin's experiments are purely focused on invisibility and have no connection to the afterlife or any metaphysical concepts.

2. **We can travel in future time**: This option is incorrect as well. The story does not involve time travel or any experiments related to moving through time. Griffin's scientific pursuits are entirely centered around invisibility, not temporal exploration.

4. **Man can live in space**: This option is also incorrect. The narrative does not address space travel or the possibility of human habitation in space. Griffin's work is grounded in the science of optics and invisibility, with no mention of space exploration.

In conclusion, Option 3 is the correct answer because the story 'Footprints Without Feet' is fundamentally about Griffin's experiments to make the human body invisible. The other options do not align with the plot or themes of the story.
