[单项选择]Our visit to the excavation of a Roman fort on a hill near Coventry was of more than archaeological interest. The year’s dig had been a fruitful one and had assembled evidence of a permanent military camp much larger than had at first been conjectured. We were greeted on the site by a group of excavators, some of them filling in a trench that had yielded an almost complete pot the day before, others enjoying the last-day luxury of a cigarette in the sun, but all happy to explain and talk about their work. If we had not already known it, nothing would have suggested that this was a party of prisoners from the nearby prison. This is not the first time that prison labor has been used in work of this kind, but here the experiment, now two years old, has proved outstandingly satisfactory.
From the archaeologists’ point of view, prisoners provide a steady force of disciplined labor throughout the entire season, men to whom it is a serious day’s work, and not the rather carefree holiday
A. found that the prisoners worked far better than students.
B. did not like the prisoners’ carefree attitude to work.
C. were willing to take only a few prisoners to work on the site.
D. were often forced to discipline the prisoners.
