Kate and Ann Petrova are twins. They are schoolgirls. The twins are very much alike, and their teachers never know which is which.

One day the teacher of English says, "Kate Petrova, take your book and come up to my table!" But Kate does not know the lesson. She cannot read the new text. So she says to her sister, "Help me, Ann! I don't know the lesson. I can't read the text. You go and do it!"

Ann stands up and goes to the teacher's table. She begins to read. She reads the text very well.

The teacher says, "You read very well, Kate Petrova, you get a five. Shut your book and sit down."

Ann goes to her place and sits down. The twins are happy. But the teacher wants to ask Ann Petrova, too. He says, "And now Ann Petrova, you take your book and come up to

my table!" And he looks at Kate.

Now Kate must go and read the text. But she cannot read it. The twins do not know what to do.

Ask two questions to the text.
