Its efforts are concentrated on immediate social and legal threats to child safety and development, ensuring that the government’s internal policies and laws effectively safeguard the youngest citizens.

Explanation

The Saha ionization equation provides a robust mathematical framework that relates the observable characteristics of a star’s light to its physical state. By analyzing which atoms are ionized and to what degree, astronomers can accurately deduce the surface temperature. The reason correctly identifies that the quantitative relationship between ionization, temperature, and pressure is what makes this determination scientifically possible.
