Question

This is year 348 BC. Aristotle is a famous Greek philosopher and scientist. One day he suddenly wakes up into future - The year 2017. He observes that the world has changed a lot.
Out of the following observations made by him, which observations are examples of change?

  3. Observation 2 & 3

Solution

The correct options are
A

Observation 1 & 2


C

Observation 2 & 3


  • Car was not present in 348 BC but in 2017, people use a car as a mode of transportation so it's a change.
  • Both in 348 BC and 2017 AD, his thirst is quenched by water so it's not a change.
  • TV was not present in 348 BC but in 2017 it was a reality so it's a change.
  • Cow used to graze fields in 348 BC and in 2017 AD also so it's not a change.

Hence, only the observations about the car and the TV are changes.
