Blank (iv)

Directions: Edit the text given below by choosing the appropriate options from the list given. Write the correct answer against the correct blank number.

So many false predictions about doom are (i) been making. It (ii) is saying that the world (iii) will soon come to an end. People say that the North and the South Poles (iv) had changed their places and lead to annihilation of all living existence.

The context shows people making predictions about future events: 'People say that the North and the South Poles (iv) _____ their places.' Since this is a direct statement/prediction about the future, 'will change' is appropriate. It shows what people claim will happen. 'Are changing' suggests it's currently happening, 'may change' indicates uncertainty, and 'would change' is conditional or reported speech - neither fits the context of a direct prediction.
