Question

archaeologists used to believe that the shang dynasty was the most powerful group in bronze age china. but recently, archaeologists have made many discoveries at sanxingdui (san-shing-dway), a site over 800 miles away from the shang capital.
like the shang, the sanxingdui culture used bronze for weapons, tools, and elaborate statues. however, the culture was separate from the shang dynasty and other cultures on the north china plain. based on objects and remains from the sanxingdui site, archaeologists believe that the sanxingdui culture was also very powerful.

based on the passage, what is one thing that archaeologists learned from the sanxingdui site?
both the shang dynasty and the sanxingdui culture made stone tools.
the sanxingdui culture was part of the shang dynasty.
there was more than one powerful culture in china during the bronze age.
the shang dynasty was more powerful than the sanxingdui culture.

Explanation:

The passage states archaeologists once thought the Shang dynasty was the only powerful Bronze Age Chinese group, but discoveries at Sanxingdui show this culture was also powerful, meaning there was more than one powerful culture in that era. The other options are incorrect: the text mentions bronze (not stone) tools, says Sanxingdui was separate from the Shang, and does not claim the Shang was more powerful.

Answer:

There was more than one powerful culture in China during the Bronze Age.
