Paragraph- Sent 1: If you build a campfire, you start with a large stack of sticks and logs.
Sent 2: As the fire burns, the stack slowly shrinks.
Sent 3: By the end of the evening, all that is left is a small pile of ashes.
Sent 4: What happened to the matter that you started with?
Sent 5: Was it destroyed by the flames?
Sent 6: It may seem that way.
Sent 7: What do you think happened?
Sent 8: The truth is that the same amount of matter still exists.
Sent 9: The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases.
Sent 10: The gases floated off into the air, leaving behind just the ashes.
Sent 11: Although matter was changed, it was not created or destroyed.
Sent 12: Because the same amount of matter still exists, we can say that matter is conserved.
Sent 13: You may wonder how it can be conserved if something is now missing?
Sent 14: Assume you had measured the mass of the wood before you burned it.
Sent 15: Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes.
Sent 16: What would you find?
Sent 17: The ashes and gases combined have the same mass as the wood you started with.
Sent 18: This example illustrates the law of conservation of mass.
Question: The fact that ashes and gases combined have the same mass as the wood you started with illustrates what law?.

Ex Output:
The law of conservation of mass.

Ex Input:
Paragraph- Sent 1: We drove about a great deal--the country at the back of Deauville, going away from the sea, is lovely--very like England--charming narrow roads with high banks and hedges on each side--big trees with spreading branches meeting overhead--stretches of green fields with cows grazing placidly and horses and colts gambolling about.
Sent 2: It is a great grazing and breeding country.
Sent 3: There are many haras (breeding stables) in the neighbourhood, and the big Norman posters are much in demand.
Sent 4: I have friends who never take their horses to the country.
Sent 5: They hire for the season a pair of strong Norman horses that go all day up and down hill at the same regular pace and who get over a vast amount of country.
Sent 6: We stopped once or twice when we were a large party, two or three carriages, and had tea at one of the numerous farmhouses that were scattered about.
Sent 7: Boiling water was a difficulty--milk, cider, good bread and butter, cheese we could always find--sometimes a galette, but a kettle and boiling water were entirely out of their habits.
Sent 8: They used to boil the water in a large black pot, and take it out with a big spoon.
Sent 9: However, it amused us, and the water really did boil.
Question: Who hires a strong pair of Norman horses for the season?.

Ex Output:
Friends.
