It is understood that when two unions quarrel over three jobs, the argument is settled by giving each union two.

A、reporter who has visited plants throughoutEurope has an impression that the pace of work is much slower here. Nobody tries too harD、Tea breaks do matter and are frequent. It is hard to measure intensity of work, butBritons give a distinct impression of going at their tasks in a more leisurely way.But is all this so terrible It certainly does not improve the gross national product or output per worker. Those observant visitors, however, have noticed something else aboutBritain. It is a pleasant place. Street crowds in Stockholm, Paris and New York move quickly and silently heads down, all in a hurry. London crowds tend to walk at an easy pace (except in the profitable, efficient city, the financial district).Every stranger is struck by the patient and orderly way in whichBritons queue for a bus; if the saleswoman is slow and out of stock she will likely say, "Oh dear, what a pity’’; the rubbish collectors stop to chat and call housewives "Luvs".Crime rises here as in every city but there still remains a gentle tone and temper that is unmatched inBerlin, Milan orDetroit. In short, what is wrong withBritain may also be what is right. Having reached a tolerable standard,Britons appear to be choosing leisure over goods. According to the passage, the argument of jobs between unions is settled by means of ______.
A、competitions in their productivity
B．providing more job opportunities
C．negotiations held between the two parties
D．obtaining 33 percent more productivity
