Read the following passage and answer the questions given below:
Time is one of the most important things and the most valuable thing in the universe. The universe is dependent upon time. If there is no existence of time, then there is nothing. This universe is a 3 dimensional which we can see. But, time is very different, Time is 4 dimensional. Time is the most valuable thing in the world. Nothing can buy a time!
Time always goes forward, It doesn't move backward. Time is a precious thing. Once, the time goes, it can be never get backed. No one can go through their past and change their life. Because time doesn't move backward. The past time can never be retrieved.
Everything in the universe is just because of the existence of time. Nothing happens before time. Everything needs time to be done. Without the existence of time, it's impossible for any event in the universe. A bit of second is also very valuable. The existence of time is very necessary for the existence of any matter in the universe.
