[单项选择]It is no longer just dirty blue-collar jobs in manufacturing that are being sucked offshore but also white-collar service jobs, which used to be considered safe from foreign competition.

These can now be delivered electronically from anywhere in the world, exposing skilled white-collar workers to greater competition.
The standard retort to such arguments is that outsourcing abroad is too small to matter m
A. Service-sector has sustained a great loss.

C. Most economists underestimated the effects of off-shoring.
