What was the significance of the halfway covenant in new england? allowed women to vote in local elections gave church membership and political rights to children of puritan church members granted church membership to native americans gave political rights to mixed-race children?

The first answer is correct. The Halfway Covenant allowed the children of unbaptized Puritans to become themselves baptized and, thereby, allowed to have political and church rights and benefits. The unbaptized parents, in comparison, had no rights in the colonies and localities whatsoever.
