Although 5 million people in a country have been illiterate each year in the past two years, the situation of illiteracy is not optimistic. The country's adult non-illiteracy rate is very low in Asia and the literacy rate is slower than that of neighboring countries. To sum it up, what does this passage mean? ['Five million people in a country are literate every year.', 'Literacy scores of a country are not comparable to those of Asian countries.', 'Unsatisfactory literacy performance in a country.', 'Literacy is too slow in a country.']
