Final answer:
The most tolerant form of intergroup relations is pluralism, while at the other end of the continuum are amalgamation, expulsion, and genocide.
Step-by-step explanation:
Intergroup relations (relationships between different groups of people) range along a spectrum between tolerance and intolerance. The most tolerant form of intergroup relations is pluralism, in which no distinction is made between minority and majority groups, but instead there's equal standing. At the other end of the continuum are amalgamation, expulsion, and even genocide-stark examples of intolerant intergroup relations.
