How do you understand
Bees are very hard-working animals, and their greatest work is pollination. On one trip, they often visit 50 to 100 flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about 80 percent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planet.

1. What was the captain’s problem
2. When did the captain’s problem start
3. How did the captain send a message to Billy
The engine of the ship stopped working.
It started just 10 hours after the ship left New York.
He sent a message to Billy by tying a note to a homing pigeon named Arny.
4. Why did the captain say “That’s a good sign”
5. Why was Arny so thirsty
Because Arny kept flying higher and farther away from the ship, showing that the note might be sent successfully.
Because he had flown in fog and over the sea, for more than four hours.
Somewhere in the Atlantic Ocean, 1862.
The captain sighed. This was the thickest fog he had ever seen. They were over 330 kilometres from the closest land, so he didn’t know where to go. The ship was on its way to Europe. Just ten hours ago they left New York, but now the engine stopped working. Clearly, they needed help!

Suddenly, the captain remembered the homing pigeons. He ran to them quickly, wrote a message for help, and tied it to Big Blue’s leg. Big Blue flew up and then returned almost right away.
The captain became more worried.

“You are our last hope, little guy,” said the captain as he tied a note to Arny, the smaller and younger of the two pigeons. The captain threw him into the air. Arny flew around and around, higher and higher. Soon, the bird was away from the ship, and the captain couldn’t see Arny anymore.
“That’s a good sign,” said the captain with more hope.
Almost 340 kilometres away, Billy heard fast-moving wings come into his building and go straight to the water bowl.

“Hi there, little guy. Well, aren’t you the thirstiest bird!” Billy smiled. Then he saw the note.
Billy knew what to do. He took the note, running as fast as he could to the company office. There, he learnt Arny had flown in fog and over the sea, for more than four hours.
Thanks to Arny, people sent help to the ship.
The captain later explained, “Arny really is the most amazing bird!”
