Which of the following played a significant role in the development of modern rules still in use today?

The development of modern rules that are still in use today has been significantly influenced by religion. Historically, many modern legal systems and ethical standards have roots in religious texts and teachings. Religious frameworks often established moral codes, which evolved into formal laws and regulations that govern behavior in various societies. For instance, principles found in religious traditions have inspired legislation pertaining to family law, property rights, and even criminal justice.

In contrast, while sports, culture, and tribal systems have also contributed to the formation of rules and guidelines within specific contexts, they do not have the same overarching impact on modern legal and ethical standards as religion does. For example, sports create rules for fair play but are limited to their specific context and do not necessarily influence broader societal norms. Similarly, while culture informs customs and traditions, it varies greatly between societies and can lead to more localized practices rather than universally applicable rules. Tribe-based governance may also set certain standards, but these are often specific to tribal systems and do not translate effectively to wider societal application.
