If a country has a very large young population but a weak education system, which future challenge may emerge?

Correct answer: Low-skilled labor force and unemployment

A very large young population can become an advantage if people receive good education and useful skills. If the education system is weak, many young people may reach working age without the knowledge or training required by employers. The economy may then face a large supply of low-skilled workers, limited productivity, underemployment, and unemployment. The challenge can be especially serious when job creation does not keep pace with the growing number of entrants.

Option A is correct because it connects weak education with a low-skilled labor force and possible unemployment. Elderly dependency does not immediately become zero merely because the population is young; other age groups still require support. Children do not suddenly disappear, and pension pressure would not be the only possible problem. The outcome is not inevitable, but it is a clear and important risk when human-capital development is inadequate.
