As an example of how this works ,when facial tissues were first put on the market in 1924 ,they were made in limited quantities and sold at 65 cents per box of 200. People liked these facial tissues immediately and began asking for them when they went into different stores. Because there was such a demand for the product, manufacturers began making tissues in larger and larger quantities. Because the manufacturers were making tissues in greater quantities, their production costs were lowered, so that the cost of tissues went down.In the meanwhile, the quality of facial tissues was constantly improving, because more manufacturers went into the business of making tissues and each manufacturer strove to make his product better than his competitors. Today, instead of costing 65 cents, a box of 200 facial tissues costs around one-third of that price, and they are both softer and stronger.
When people are free to compete--when they are free to make more things and make them better--everyone benefits.
According to the passage, we know the word "tissue" in Para. 2 Line 1 means "______".
A.cell
B.soft paper
C.organization
D.thin fibre
