Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions from 1 to 7. 

     Companies big and small are plotting their post-pandemic working futures, and it seems likely that ever fewer of us will fully return to the office as it was before. If the Covid-19 crisis subsides and economies can largely reopen, the experiences of so many people working from home over the past year will surely shape what happens next. For many of us, this could emerge as a return to the office for three days a week. Patterns will obviously vary, but a common aand Friday at home. 

     This coming shift will largely be driven by employers making a calculation between two different, equally important forces. One is what companies see as the need for in-person creativity and connections, which will spur their desire to bring people back into offices. For many, we are at our most creative working face to face, meeting people, talking over lunch and coffee, or gathering in groups. At home, however, we tend to be more efficient in the daily tasks that make up much of working life. This is the competing force that may keep many of us out of the office, even after Covid. Working at home under the right conditions - which means in your own room with good broadband and no children around - can be highly efficient. This greater efficiency on current tasks also combines with other factors, like the time saved by avoiding the daily commute, offering a compelling reason for people to stay at home. The past year of Covid home working has perhaps opened many more people's eyes to this. 

     As companies come to decisions on new working arrangements, they will be essentially making a basic trade-off: the expectation of greater creativity in new projects at the office, but greater productivity on existing tasks at home. And, as with most trade-offs, the right answer is not all or nothing - but something in the middle. Employees seem to prefer this working pattern too. In a recent survey of 5,000 employees in Britain, working in the office for three days a week was the most popular choice. Not only is this pattern more efficient for companies, then, but it also helps to keep employees happy and motivated.
