Question

in this excerpt, the author states that plans are \already in the works\ for even bigger structures. this suggests that

a the principles used in future buildings will not be much different than those used in ancient ones.

b new buildings will be safe but very expensive to build.

c new structures will eventually be made that will be larger than the ones mentioned in the selection.

d modern engineering can no longer find new ways to build things.

these three creations are true marvels of the modern age. they are in the record books today for being the biggest and the best in the world. but plans are already in the works for even taller buildings and longer tunnels and bridges. modern engineering continues to push the edges in search of bigger, better, faster, more. what exactly will tomorrow hold?

Explanation:

The text notes current structures are the biggest/best, but plans are underway for even taller buildings, longer tunnels/bridges. This directly aligns with the idea that larger structures than the current ones will be created. Options A, B, and D have no support in the provided excerpt.

Answer:

C. new structures will eventually be made that will be larger than the ones mentioned in the selection.
