What is the age of the Great Wall?

  1. About 1 billion years

  2. About 10 billion years

  3. About 100 billion years

  4. About 1 trillion years


Correct Option: B
Explanation:

The Great Wall is estimated to be about 10 billion years old, which makes it one of the oldest structures in the universe.

How was the Great Wall formed?

  1. By the collision of two superclusters of galaxies

  2. By the gravitational collapse of a large cloud of gas and dust

  3. By the merger of two smaller galaxies

  4. By the expansion of the universe


Correct Option: B
Explanation:

The Great Wall is thought to have been formed by the gravitational collapse of a large cloud of gas and dust. This collapse would have caused the gas and dust to clump together and form galaxies and galaxy clusters.

What is the future of the Great Wall?

  1. It will continue to grow in size

  2. It will eventually collapse in on itself

  3. It will be torn apart by the expansion of the universe

  4. It will remain the same size


Correct Option: A
Explanation:

The Great Wall is thought to be still growing in size as new galaxies and galaxy clusters are formed. This growth is expected to continue for billions of years.

What is the significance of the Great Wall?

  1. It is the largest known structure in the universe

  2. It is the oldest known structure in the universe

  3. It is the most massive known structure in the universe

  4. It is all of the above


Correct Option: D
Explanation:

The Great Wall is the largest, oldest, and most massive known structure in the universe. It is a fascinating object that is still being studied by astronomers.
