input: Please answer the following: W: Yes, I know this quite well. But still there are some children who can't go to school because of their poverty. M: Yes, it's a matter of money. You see, education here is not completely free for the students. If it were so it would cost the government too much money. W: Do all parents send their children to state schools? M: Yes, nearly all of them. If you are rich, you may prefer to send your children to private schools, but it takes a lot of money. What was said before this conversation?

input question: W: I'm planting cabbage. M: What's that in your hand? W: Cabbage seed. You see, I put some soil in the box, sow the seed carefully like this, and then cover it with more soil. I'll keep the box in the shade so that the sun doesn't burn the little plants. M: Is that all? W: No. Later, in a few weeks' time I'll put the little plants in the earth. Then I'll water them to stop the soil from getting too dry. Several weeks after that, I will plant them in rows in the field. M: Do you have to feed plants like you feed chickens? Or do they grow up by themselves? W: In fact they grow better if you feed them. When the plants are in the ground I'll put some powder on the soil. The powder is made from fish, blood and bones. It'll make the cabbage plants grow big and strong. M: Like me! What was said before this conversation????
