[单项选择]Time, as we know it, is a very recent invention. The modern time-sense is hardly older than the United States. It is a by-product of industrialism--a sort of psychological analogue of synthetic perfumes and aniline dyes.
Time is our tyrant. We are chronically aware of the moving minute hand, even of the moving second hand. We have to be. There are trains to be caught, clocks to be punched, tasks to be done in specified periods, records to be broken by fractions of a second, machines that set the pace and have to be kept up with.
Another time-emphasizing entity is the factory and its dependent, the office. Factories exist for the purpose of getting certain quantities of goods made in a certain time. The old artisan worked as it suited him with the result that consumers generally had to wait for the goods they had ordered from him. The factory is a device for making workmen hurry. The machine revolves so often each minute; so many movements have to be made, so many pieces produ

[单项选择]Early that June Pins XII secretly addressed the Sacred College of Cardinals on the extermination of the Jews. "Every word we address to the competent authority on this subject, and all our public utterances," he said in explanation of his reluctance to express more open condemnation, "have to be carefully weighed and measured by us in the interest of the victims themselves, lest, contrary to our intentions, we make their situation worse and harder to bear."

The record of the Allies was far more shamefu
