Context: Scores of people queued up to use a cash machine after it started giving out double the money requested. The cash machine, outside a Sainsbury's store in Barham Road, Hull, attracted a big crowd of people hoping to take advantage of the fault, on Tuesday night. Police officers were eventually sent in to guard the machine and prevent anymore money from being withdrawn. The fault is thought to have affected cash machines at supermarkets across the city. It is not yet known whether the customers will have to repay the cash or how much money was taken out. A spokeswoman for Humberside Police said, "Officers were sent to the cash machine to prevent anyone else from withdrawing anymore money. We have also tried to make contact with the owners of the machine." The spokeswoman said those who benefited from the fault could be traced and could face theft charges, but investigations would only take place if the operator made a complaint. The cash machine is owned by a company called Payzone, a spokesman later confirmed. He said the fault was due to the machine being filled with notes of the wrong denomination . An investigation is underway into the incident and the machine had been taken out of service, he added. The Payzone spokesman said, "The transit company which is contracted to service this ATM has filled it up with the wrong denomination of notes, meaning it is paying out double what it should have. " He could not say how much money had been taken out of the machine, or whether it would have to be paid back. It was understood that a number of cash machines in Hull owned by other companies had also been affected by this problem, he added. 
 Question: Who caused the cash machine not to work properly?

Ex Output:
the transit company.

Context: People all over the world today are beginning to hear and learn more and more about the problem of pollution.Pollution is caused either by man's release of completely new artificial substances into the environment,or by releasing greatly increased amounts of a natural substance,such as oil from oil tankers into the sea. The whole industrial process which makes many of the goods and machines we need and use in our daily lives,is bound to create a number of waste products which upset the environmental balance,or the ecological balance as is also known.Many of these waste products can be prevented or disposed of.But while more and more new and complex goods are produced,there will be new,dangerous waste to be disposed of,for example,the waste products from nuclear power stations.Many people,therefore,see pollution as only part of a larger and more complex problem,that is,the whole process of industrial production and consumption of goods.Others again see the problem mainly in connection with agriculture,where new methods are helping farmers grow more and more on their land to feed our ever-increasing population.However,the land itself is gradually becoming worn out as it is being used,in some cases,too heavily,and artificial fertilizers can not restore the balance. Whatever its underlying reasons are,there is no doubt that much of the pollution caused could be controlled if only companies,individuals and governments would make more efforts.In the home there is an obvious need to control litter and waste.Food comes wrapped up three or four times in packages that all have to be disposed of;drinks are increasingly sold in bottles or tins which can not be reused.This not only causes a litter problem,but also is a great waste of resources,in terms of glass,metals and paper.Advertising has helped this process by persuading many of us not only to buy things we neither want nor need,but also to throw away much of what we do buy.Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying,excessive consumption and careless disposal of the products we use in our daily lives. 
 Question: Many people see pollution as only part of .

Ex Output:
the whole process of industrial production and consumption of goods
