2. This option implies that lawmakers are reacting to issues that are deemed essential or urgent by the public, such as healthcare reform, environmental protection, or education initiatives.
3. By considering and addressing societal needs, Congress aims to improve the well-being of the population and address pressing concerns that impact society as a whole.
4. Therefore, when analyzing the reasons behind the laws passed by Congress, focusing on perceived societal needs helps understand the legislative process and the priorities of lawmakers in responding to the demands and challenges faced by the population.
