The following appeared in the editorial column of a local daily newspaper:"The city corporation made the right decision when it unanimously voted to convert the public library system into a computer-skills training facility for public use. The converted facility will fill what is certain, based on national trends, to be a growing need among country residents for training in computer skills. And since our library system boasts more volumes per resident than any other system in the city corporation area, the remaining branches will adequately serve the future needs of the residents".Discuss what evidence you would need to properly evaluate the argument, and explain how evidence might strengthen or weaken the argument.
