M: Hello Jane.

W: Hello Paul.

M: Please coming. I’m just getting ready to go home. Susan is expectingme for dinner. I wanted to be on time for a change.

M: What will it cost, Jane?

W: A small percentage, about 1% and that can be built into the price ofthe bike.

M: Well, I don’t suppose there is much choice. All right Jane, let’sput it into action.

Q9: What do we learn aboutthe man’s daily life?

Q10: Why did the woman cometo see the man?

Q11: What makes the womanworry about the Indian Rupee?
