With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: There is a single government-owned radio network, a growing number of private radio stations, and one government TV station. The fixed telephone system, with just 18,000 lines, serves the few inhabitants who used landlines in 2012, but the wireless communications systems remain inadequate. The mobile cellular system is growing rapidly and had an estimated 4.8 million lines in 2012. Internet usage is very low, reaching just 1.5% of the population in 2012.
text_B: If an economist had only read that short sentence about the telephone network and thus knew nothing else about this country (not even its name or location), would he be more likely to guess that this is a country like Sweden where mobile phones were established due to the astonishingly high costs of the otherwise world-class telephone system (made justifiably famous in the opening credits to Monty Python and the Holy Grail) rather than a country in Africa, where residents were practically forced to leapfrog over woeful utility service and into the modern cellular era.
YES.
