Hello,

Improve the following sentences through the use of proper parallel constructions:-

- Oil reserves in Texas are not as great as Alaska.

Can I answer it this way?

Oil reserves in Texas are not as great as oil reserves in Alaska.
Yes, but I think you can also do it more concisely:

Oil reserves in Texas are not as great as in Alaska.
But what if I answered it in this way?

Will it be considered correct?
