Read the passage carefully, then choose the best answer for each question.
WHO WAS SACAGAWEA?
There are more statues of her than of any other American woman. Her face is on a U.S. coin. Clearly, she was an important person. But what do we know about the real Sacagawea?
Sacagawea was part of a Native American tribe called the Shoshone. At the age of 13, she was taken away by people from the Hidatsa tribe. She was living among the Hidatsa when Meriwether Lewis and William Clark met her in 1804.
Meriwether Lewis and William Clark were mapmakers. These pioneers were exploring the western part of the U.S. Because Sacagawea spoke two different Native American languages, they asked her to travel with them, along with her husband and baby son.
Sacagawea became an important part of the group and helped the explorers in many ways. For example, on May 14, 1805, a strong storm tipped over  one of their boats. Sacagawea stayed calm. She acted quickly and was able to save many of the maps and other things from the water. Her actions saved important knowledge from being lost.
As they traveled, Sacagawea helped Lewis and Clark talk to the Native American people in each village they visited. She helped the explorers make friends among the Native Americans, so they could trade with them. She also helped Lewis and Clark find a way across the mountains to the Pacific Ocean, and helped them find food on the way.
Sacagawea died when she was about 25. Sadly, we don't know much more about this amazing woman. But two hundred years later, she is remembered as an important woman in U.S. history.

C.She started living with the Hidatsa tribe when she was 13 years old.
D.Sacagawea helped Lewis and Clark in many ways.
