The Great Pyramid is about 137 metres high today, but it was once A. higher B. highest C. high too D. more high A. higher B. highest C. high too D. much high

The Great Pyramid's current height of 137 metres is lower than its original height due to erosion and the loss of its outer casing stones. This comparison requires the comparative form of the adjective "high."

Answer: A. higher

The structure "was once..." implies a comparison between the pyramid's past and present state. The correct comparative form of "high" is "higher" (not "more high," which is grammatically incorrect). "Highest" would require comparing to multiple other structures, which isn't the case here. When you visit the Great Pyramid today, you're seeing a structure that's approximately 9 metres shorter than it was when it was first built—proof that even the most enduring monuments change over time. Have you ever wondered how ancient engineers ensured such precise measurements with the tools available to them?
