Final answer:
The MCC promoted uniformity of play in cricket by codifying the rules to ensure the game was played fairly and consistently. Promotion of cricket by the MCC had nothing to do with cricket as a religion or drug use, which is against the spirit of sport.
Step-by-step explanation:
The Marylebone Cricket Club (MCC) played a significant role in the promotion and development of cricket. One important aspect of the MCC's promotion was to encourage uniformity of play throughout the game. This included codifying the rules, which brought a standard set of rules to the game that could be universally applied, thereby ensuring that cricket was played fairly and consistently across different regions.
The promotion of cricket by the MCC did not involve endorsement of cricket as a religious practice or the use of performance-enhancing drugs. On the contrary, sports authorities, including those associated with cricket, have historically taken a strong stance against the use of such drugs due to the potential health risks, the importance of equality of opportunity, and the desire to maintain the spirit of sport.
