the empire state building has a tall antenna on its roof.
the chrysler building is shorter than the empire state building.
the chrysler building was built before the empire state building.
the empire state building was once the tallest building in the world.

Explanation:

To find the central idea, we analyze each option:

• The first option is a detail about the Empire State Building's antenna, not a central idea.
• The second option compares heights but is likely a supporting detail.
• The third option is about the building time, also a detail.
• The fourth option states a significant fact about the Empire State Building's status as the tallest building, which is a central idea as it conveys a main point about the building's significance.

Answer:

D. The Empire State Building was once the tallest building in the world.
