Answer:
A
Step-by-step explanation:
We want to find a passage that would not be useful when researching structures that don't exist anymore.
A: The Pyramids of Egypt are still standing today. If someone if researching structures that no longer exist, this wouldn't be helpful, because this structure still exists.
B: The Colossus of Rhodes was a statue that stood for 56 years, but it was ruined by an earthquake in 226 BCE. A paragraph on this structure would be helpful, because it no longer exists.
C: The Pharos of Alexandria was a lighthouse. It was also destroyed by an earthquake, in approximately 1480 . This would be helpful because this is also in ruins and no longer stands.
D: The Statue of Zeus at Olympia was lost in a fire in the 5th century. Since it no longer exists, this would be helpful.
Therefore, the passage that would be irrelevant when researching ancient structures that no longer exist is A: the paragraph about the Pyramids of Egypt.
