Select the most appropriate option to fill in blank no.4.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. were.
The passage talks about the planet Earth. As the line talks about the position where you stand so that you are nearer the centre of the earth, so, the appropriate word for filler 4 is 'were' as 'if + were' is used to indicate an assumption.
