Final answer:
The Pyramids of Giza and the Islands of Dubai can be seen from space, but the Great Wall of China cannot.
Step-by-step explanation:
Great Wall of China: The Great Wall of China can not be seen from space. This is a common misconception, but it has been confirmed by astronauts that the Great Wall is not visible from outer space. It is, however, a significant man-made structure that extends for thousands of kilometers across China.
Pyramids of Giza: The Pyramids of Giza can be seen from space. These ancient structures are among the most famous and well-known landmarks in the world, and they have been photographed from space by astronauts. Their massive size and unique shape make them visible from a great distance.
The Islands of Dubai: The Islands of Dubai can be seen from space. These man-made islands are a popular tourist attraction and can be seen from space due to their large size and distinct shape.
None of these: This option is not correct, as both the Pyramids of Giza and the Islands of Dubai can be seen from space. The Great Wall of China, however, cannot be seen from space.
