Read the sentence to find out whether there is any error in it or not. The error, if any, will be in one part of the sentence. The number of that part (which has the error) is the answer. If there is no error, the answer is (4). Ignore errors of punctuation, if any. There is no way that a population of nine (1)/ billion can meet it’s energy needs(2)/ without causing damage to the planet(3). No error (4)?

Option 2 : billion can meet it’s energy needs

The error is in part 2 as the contraction ‘it’s’ is incorrect. The statement should be ‘can meet its energy needs’ instead of ‘can meet it’s energy needs’.

Therefore the correct statement is:

There is no way that a population of nine billion can meet its energy needs without causing damage to the planet.

Usage of ‘its’ for better understanding are as follows:

The fish is too big for its aquarium.

He put the book back into its place.

On the other hand, the usage of it’s is as under:

It’s his fault that he forgot to bring his pen.

It’s a fact that human body undergoes changes from time to time.
