Answer:
A sect is far less likely to proselytize, or try to recruit new members; NRMs, on the other hand, spend much of their resources in trying to expand their membership.
Explanation:
Sect is a term that describes a subgroup of people that carved out from the existing but bigger religion, such that their beliefs and practices are slightly different at superficial level. For example Amish religion is considered a sect to Protestant faith.
While NRM which is an acronym for New Religion Movement is a term that explains the religion or form of spirituality whose forms is attributed to modern ideology or origin, such that, it infuses the existing societal norms and cultures into its practices and beliefs. For example Christian Reformed Church in North AmericaAmerica
Thus, Sect already has the exisiting members or group of people carved out with the teachings and practices well known among its members. However, NRM, due to its formations, do put more efforts in getting new and more members in their movement, by preaching their teachings and set of beliefs to people so as to entice the public towards them.
