POLAR PIONEER
Matthew Henson: Arctic Explorer
Robert Peary and Matthew Henson both wanted to be great explorers. When Peary needed someone to join him on his trip to the North Pole, he thought of Henson. They had once worked together in Central America. At the time, it was unusual for an African American to be a well-known explorer. Henson wanted to change that. So, though he knew the trip would be hard, he agreed to go.
First, they traveled by ship to Greenland. The members of Peary's team lived among the Inuit people there. The Inuit called Henson "Maripaluk—Matthew, the Kind One.” Henson learned their language. The Inuit taught him how to live outdoors on the ice, find food, build igloos, make snowshoes, and drive dogsleds through the snow and ice.
To the Top of the World
Between 1891 and 1906, the Peary-Henson team made seven attempts to get to the North Pole. Each time, they learned hard lessons about the dangers there. Sleds broke. Dogs died. Men got hurt. They got close to the North Pole, but they always had to go back.
In 1909, they decided to make one more attempt. Peary and Henson found themselves within 56 kilometers (35 miles) of the North Pole. Peary sent Henson ahead. Henson made a trail through the snow for Peary to follow. Peary followed 45 minutes later. "I think I am the first man to sit on top of the world,” Henson told Peary.
The team returned home as heroes. Both men's dreams had come true: They were the first explorers to reach the North Pole.
What is the main idea of the second paragraph?
A.The Inuit have a difficult life in Greenland.
B.Henson learned how to speak the Inuit language.
C.The Inuit gave Henson a name.
D.Henson learned many things from the Inuit.

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.
Which of the following sentences is likely to be true?
A.The author thinks Sacagawea was too young to travel.
B.The author would like to know more about Sacagawea.
C.The author believes the story of Sacagawea is not true.
D.The author thinks Sacagawea didn’t deserve to be remembered.

THE DISEASE DETECTIVE
Six children were in the hospital. They were very sick, but the doctors didn't know what to do. They called Dr. Richard Besser, an expert on strange illnesses. Dr. Besser knew just what to do.
Finding a Cause
First, Dr. Besser needed to find the cause of the illness. He used a microscope to look for germs like bacteria in the children's bodies. Dr. Besser found that all the children had a strain of the bacteria E. coli. Then he looked at the bacteria's DNA. The DNA showed him that this strain of E. coli was dangerous to humans.
Where Did It Come From?
Dr. Besser knew E. coli could move from animals to humans. Perhaps the children had touched animals that carried the bacteria? Besser found other E. coli cases in the area where the children lived. But it wasn't enough.
Besser then made a list of what the sick children had eaten. They had all eaten cheese, apple juice, and fish. He then made a list of what healthy children in the area had eaten, and compared his lists. They had eaten the cheese and fish, but not the apple juice.
Case Closed
Besser went to where the apple juice was made. He saw that there were animals around the apple trees, and he saw the workers using dirty apples that had fallen on the ground. More importantly, he saw that the apples were not washed before the juice was made, and that the juice was not heated. Doing these things would kill the bacteria. Besser then knew it was the apple juice that made the children sick.
Besser's E. coli case has a happy ending. The children got better. And what Besser learned that day now helps keep others safe.
Which of the following is NOT true about E. coli?
A.It’s a kind of plant.
B.It can make people sick.
C.It moves from animals to people.
D.It’s dangerous to humans.
