Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 21 to 25.

One of the seven wonders of the ancient world, the Great Pyramid of Giza was a monument of wisdom and prophecy built as a tomb for Pharaoh Cheops in 2720 B.C. Despite its antiquity, certain aspects of its construction make it one of the truly great wonders of the world. The thirteen-acre structure near the Nile River is a solid mass of stone blocks covered with limestone. Inside are a number of hidden passageways and the burial chamber for the Pharaoh. It is the largest single structure in the world. The four sides of the pyramid are aligned almost exactly on true north, south, east, and west – an incredible engineering feat. The ancient Egyptians were sun worshipers and great astronomers, so computations for the Great Pyramid were based on astronomical observations.

Explorations and detailed examinations of the base of the structure reveal many intersecting lines. Further scientific study indicates that these represent a type of timeline of events – past, present, and future. Many of the events have been interpreted and found to coincide with known facts of the past. Others are prophesied for future generations and are currently under investigation. Many believe that pyramids have supernatural powers, and this one is no exception. Some researchers even associate it with extraterrestrial beings of the ancient past. Was this superstructure made by ordinary beings, or one built by a race far superior to any known today?

The word “intersecting” in paragraph 2 is closest in meaning to ____.
