Two hundred years ago, the clock began to control the world of work. Paid on the basis of how many hours they worked, people rushed to and from work.

The clock’s power may at last be weakening. Flexible working existed well before the pandemic?(疫情). Now remote working has brought a greater degree of freedom. A survey of 4,700 home-workers across six countries conducted by Slack, a corporate-messaging firm, found that flexible working was viewed very positively, improving both people’s worksite balance and productivity. Flexible workers even scored more highly on a sense of belonging to their organization than those on a nine-to-five schedule.

It is hardly surprising that workers prefer flexibility. Working an eight-hour schedule is restricting. Those are also the hours when most shops are open, and when doctors will take appointments. Parents on a conventional routine may be able to take their children to school in the morning but are unlikely to be able to pick them up in the afternoon.

It is also not astonishing that home-workers feel they are more productive. After all, few people can concentrate for eight hours on end. There are points in the day where people feel like staring out of the window or going for a walk; these may be moments when they find inspiration or recharge themselves for the next task. When they do this in an office, they risk the boss’s disapproval; at home, they can work when they are most motivated.

What is striking about Slack’s study is the widespread support for home-working. Overall Just 12% of the workers surveyed wanted to return to a normal office schedule. In America black, Asian and Hispanic employees were even more enthusiastic than their white colleagues. Women with children were generally happy about it, reporting an improvement in their work-life balance.

Of course, the new schedule carries dangers: people may lose all separation between work and home life. To maintain some human contact, companies may adopt a mixed model in which workers go into the office for part of the week. But overall office-workers’ freedom is to be welcomed. The clock was a crud master and many people will be happy to escape its control.

I am Peter Hodes, a volunteer stem cell courier. Since March 2012, I've done 89 trips — of those, 51 have been abroad. I have 42 hours to carry stem cells (干细胞) in my little box because I've got two ice packs and that's how long they last. In all, from the time the stem cells are harvested from a donor (捐献者) to the time they can be implanted in the patient, we've got 72 hours at most. So I am always conscious of time.

Which of the following can replace the underlined word “courier” in Paragraph 1?

“When you leave work you’re usually an expert in whatever you did. Then you start something new and everyone is younger than you, they know more than you do, they’re probably better at risk-taking, I think they’re better educated. It’s easy to feel intimidated (胆怯的). But remember you have skills that you’ll be able to build on.” Allison says, “Art gives me a different place in the world. When I’m making staff, and I’m hard at it, I feel very joyful.”

Which word can best describe Allison Barnes according to the last paragraph?
