Incipience, or the preliminary stage, occurs when a group of people becomes aware of a social problem and begins to feel a shared sense of grievance. This stage is marked by a general mood of discontent before the movement becomes organized or gains significant public attention. It serves as the foundation upon which later stages, such as coalescence and bureaucratization, are built.

While 'social change' is the broader term for these alterations, the provided answer key identifies 'social movements' as the correct choice. Social movements are organized efforts by groups to promote or resist change, and they are a primary mechanism through which structural and cultural shifts are enacted in society.

International Human Solidarity Day is an annual observance established by the United Nations General Assembly. It is celebrated on December 20th to highlight the importance of solidarity as a fundamental value in international relations. The day serves to remind governments to respect their commitments to international agreements and to raise public awareness about the necessity of global cooperation in addressing poverty and social inequality.

Resource Mobilization Theory (often referred to as Resource Development in some contexts) is a major sociological theory that emphasizes the importance of resources—such as money, labor, and organizational skills—in the success of social movements. It posits that movements are not just products of grievances, but require the strategic mobilization of resources to achieve their goals, making it a dominant academic perspective.

The term 'terrorism' originated during the French Revolution, specifically during the 'Reign of Terror' (1793–1794). It was initially used to describe the actions of the revolutionary government, which utilized systematic violence and intimidation to suppress perceived enemies of the state. Over time, the meaning of the word evolved from state-sponsored repression to describe non-state actors using violence to achieve political goals, but its etymological roots remain firmly in this historical period.

Social movements are organized efforts by groups of people to bring about or resist social change. These movements are not restricted by scale; they can emerge at the local level, expand to regional or national levels, and in the modern era, frequently operate on a global scale to address transnational issues.

Frame extension occurs when a social movement organization expands its primary frame to encompass interests or points of view that are incidental to its primary objectives, thereby attracting a broader base of support.

A revolutionary movement is a type of social movement dedicated to carrying out a revolution. Unlike reform movements, which seek to change specific aspects of a system, revolutionary movements aim to overthrow the existing social, political, or economic order and replace it with a completely new structure.

New social movements (NSMs) typically focus on identity, quality of life, and cultural issues rather than purely economic or class-based struggles. The labor movement is considered an 'old' social movement because it is rooted in industrial class conflict and economic demands, whereas environmental and anti-nuclear movements are classic examples of NSMs.

Social movements are defined as sustained, organized efforts by a large group of people to bring about or resist social change. Unlike crowds, which are often temporary and spontaneous, or rumors, which are fleeting, social movements possess a structured organization and long-term goals, making them the most encompassing form of collective behavior in sociological study.
