Multiple Choice 1 point What common theme emerges when comparing astronomical sites across different continents? They all used the same building materials They were all built by the same civilization They all demonstrate a shared fascination with the cosmos They were all abandoned at the same time

## Step 1<br />The problem is asking us to identify a common theme that emerges when comparing astronomical sites across different continents. The options provided are:<br />- They all used the same building materials<br />- They were all built by the same civilization<br />- They all demonstrate a shared fascination with the cosmos<br />- They were all abandoned at the same time<br /><br />## Step 2<br />We need to analyze each option and determine which one is the most likely common theme among astronomical sites across different continents.<br /><br />## Step 3<br />The first option, "They all used the same building materials", is unlikely because different civilizations had access to different resources and technologies, which would have influenced the materials they used.<br /><br />## Step 4<br />The second option, "They were all built by the same civilization", is also unlikely because astronomical sites were built by different civilizations across different continents.<br /><br />## Step 5<br />The third option, "They all demonstrate a shared fascination with the cosmos", is the most likely common theme. Regardless of the civilization or the materials used, the primary purpose of astronomical sites is to observe and understand the cosmos.<br /><br />## Step 6<br />The fourth option, "They were all abandoned at the same time", is unlikely because the abandonment of these sites would have been influenced by various factors such as cultural shifts, technological advancements, and environmental changes, which would have varied across different civilizations and continents.
