Question 51-52refer to the following information. The bad news about a slow-but-steady recovery is clear: lingering long-term unemployment, stagnant wages, and a housing recovery that is leaving many middle-income families behind. But one interesting side-effect of the boring recovery is that it puts to rest （for now） the popular fears of an AI/robot revolution taking all of our jobs. In that brave neo-industrial world, one thing you would expect to see is GDP growth rapidly outstripping employment, as robots did a bunch of work while Americans sat around waiting for federal welfare checks. Quite the opposite, in the last few years, GDP-per-worker has all but stopped growing. What does the word “outstripping “mean?
A. Promoting B. Exceeding. C. Improving D. Technicians.
