According to the signaling view of education, education a. only helps firms sort workers into high-ability and low-ability workers b. increases human capital and the wages of workers c. can make any worker into a superstar d. reduces the wage gap between highly-educated and less-educated workers

The signaling view of education primarily suggests that education serves as a signal to employers about a worker's ability rather than necessarily increasing their actual productivity or human capital. Let's analyze the options: a. **Only helps firms sort workers into high-ability and low-ability workers**: This aligns closely with the signaling view, as it emphasizes the role of education in signaling rather than enhancing skills. b. **Increases human capital and the wages of workers**: This is more aligned with the human capital theory, which posits that education increases skills and productivity. c. **Can make any worker into a superstar**: This is an exaggeration and not supported by the signaling view, which does not claim that education can universally elevate all workers to high levels of success. d. **Reduces the wage gap between highly-educated and less-educated workers**: This is not a direct implication of the signaling view, which suggests that the wage gap may persist due to the signaling function of education. Based on this analysis, the correct answer that aligns with the signaling view of education is: **a. only helps firms sort workers into high-ability and low-ability workers.**
