Q1820855 Inglês
LEIA O ARTIGO SOBRE TECNOLOGIA E RESPONDA A QUESTÃO. 

Modern and convenient — or are they?
history, people have felt that they are the most modern generation. Ever since the invention of the wheel or the building of the first bridge, people have said that the things now are more advanced, more efficient than ever before.
This has never been truer than in the early twenty first century. We love — and sometimes hate – our computers and related technologies. But do we use them well? 
Take mobile phones, for example. They started as an expensive luxury, used by the very rich, and have become a necessary item of business equipment. We can’t image without one. But many of those calls are not half assurgent as we think.
Most people talking on the phone on the train could easily wait until they in the office – and they should remember that the other passengers can hear what they are saying: what if one of your competitors is sitting on the train, too?
Then take email. It hasn't always been here.
Business worked with letters and phones for a very long time before email, but these days everybody seems to use it — but do they use it well? People think it’s quick, and that it makes everything quicker, and that quicker is good. But we need to be careful as well as quick. So, before you click to send the reply to that very urgent message, check it through carefully. People often just use the spell-check, but make sure the facts are correct, too, and that your message is polite.
Or take online ordering. This Has been with us for a very short time, but already there are businesses that run only online. What some companies forget is that older customers often have a lot of money to spend. But this type of customer wants to talk to a person, not a machine.
what problem does the writer describe about online ordering?
