(First-price sealed-bid auction) Alice is selling her 2000 chevrolet cavalier to her friends, Bob and Charles. Bob attaches a value of S$8,000 to Alice's old car, while Charles's value of the car is S$10,000. (These valuations are common knowledge between Bob and Charles.) Alice designs the following auction to sell her car: First, she asks each of them to write his bid on a piece of paper. Then Bob and Charles give their bids (nonnegative integers) to Alice. Notice that when Bob and Charles write down their bids, they don't know each other's bid (so called "sealed bid"). After Alice receives the sealed bids, the bids are shown to everyone, and the car will be sold to the person who has the higher bid at the price equal to his own bid. When there is a tie (Bob and Charles bid the same amount), then Alice would flip a fair coin to decide who will get the car. In this game, Bob has 8000 strategies and Charles has 10000 strategies.

The wholesaler buys goods in large quantities from the manufacturers and sells them in smaller parcels to retailers, and for this service his selling price to the retailer is raised several percent higher. But his job is made more difficult by retail demand not necessarily running level with manufacturers' production. Because he adjusts or regulates the flow of goods by holding stock until required, he frees the manufacturer, to some extent, from the effect on production of changing demand and having to bear the whole risk.
The manufacturer can then keep up a steady production flow, and the retailer has no need to hold heavy stocks, who can call on the wholesaler for supplies any time. This wholesale function is like that of a valve in a water pipe. The middleman also bears part of the risk that would otherwise fall on the manufacturer and also the retailer.
The wholesaler provides a purely commercial service, for which he is too well rewarded. But the point that is missed by many people is that the wholesaler is not just someone adding to the cost of goods. It is true one could eliminate the wholesaler but one would still be left with his function: that of making sure that goods find their way to the people who want them.
"Middleman" in the passage almost equals to all the following in meaning EXCEPT______.
A.go-between
B.intermediary
C.manufacturer
D.wholesaler
