question 1 of 5
in the midst of dramatically increasing population density, a rapidly evolving and changing economy, and a growing need for skilled laborers in a variety of industries, bn vocational school is hard at work to make a better future for china, one student at a time
over the last four decades, chinas population has undergone a sweeping shift from rural farming villages to rapidly expanding cities. mandatory benefits and state - regulated wages have provided better prospects for migrant workers who dont mind doing the jobs urban residents consider \dirty\ or too dangerous. however, it is not as easy for the migrants children. unless they can acquire job - relevant training, many of these relocated families will find themselves unemployed as the economy transitions to a more specialized workforce. for this reason, free and low - cost vocational education is in high demand
public perception of vocational schools, and how this affects policy and regulation has also done a disservice to the institution. historically, the chinese people have esteemed higher education and have a low regard for someone who works in the trades. state - run vocational schools are plagued by budget shortfalls,
according to the passage, one - third of domestically produced products in china meet quality - control standards because:
a the speed of production is too fast to ensure consistency
b inferior materials are being used as a cost - cutting measure.
c workers are not adequately trained to operate machinery.
d the standards of quality control are impossibly high.

Explanation:

The passage discusses China's changing economy and the need for skilled laborers. It mentions that urban residents consider certain jobs "dirty" or dangerous, and unless migrants' children can acquire job - relevant training, they may face unemployment. This implies that a lack of proper training (workers not being adequately trained to operate machinery) is a factor. Option C aligns with this as it points out a training - related issue which could affect quality control (if workers can't operate machinery properly, quality might be compromised). Options A (speed of production) and B (inferior materials) are not mentioned in the context related to quality - control standards. Option D (impossibly high quality standards) is also not supported by the text.

Answer:

C. workers are not adequately trained to operate machinery.
