Section A
Scientists scanning and mapping the Giza pyramids say they&39;ve discovered that the Great Pyramid of Giza is not exactly even. But really not by much. This pyramid is the oldest of the world‘s Seven Wonders. The pyramid’s exact size has (26) puzzled experts for centuries， as the “more than 21 acres of hard， white casing stones” that originally covered it were (27) removed long ago.
Reporting in the most recent issue of the newsletter “AERAGRAM，” which (28) chronicles the work of the Ancient Egypt Research Associates， engineer Glen Dash says that by using a new measuring approach that involved finding any surviving (29) remnants of the casing in order to determine where the original edge was. They found the east side of the pyramid to be a (30)maximum of 5.55 inches shorter than the west side.
The question that most (31) fascinates him， however， isn&39;t how the Egyptians who designed and built the pyramid got it wrong 4，500 years ago， but how they got it so close to (32) perfect. “We can only speculate as to how the Egyptians could have laid out these lines with such (33) precision using only the tools they had，”Dash writes. He says his (34) hypothesis is that the Egyptians laid out their design on a grid， noting that the great pyramid is oriented only (35) slightly away from the cardinal directions (its north-south axis runs 3 minutes 54 seconds west of due north， while its east-west axis runs 3 minutes 51 seconds north of due east)—an amount that&39;s “tiny， but similar，” Atlas Obscura points out.
