问题如下：
Which of the following is most likely to be correct?
选项：
A.Total factor productivity can be directly observed in the economy.
B.Total factor productivity is reflected by the technological change.
C.Total factor productivity is accounted for the capital inputs.
解释：
B is correct.
Total factor productivity is not accounted for the capital and labor inputs.Total factor productivity can not be directly observed in the economy and must be estimated.
考点： Total factor productivit
解析： Total factor productivit不能够被直接观测到，通常一国经济增长扣除劳动力增长部分以及资本增长部分后，得到的剩余部分就是 Total factor productivit 部分。所以A选项错误。
Total factor productivit 主要受技术进步的影响，所以B选项正确。
C选项说法错误，是一个打酱油的选项。
