Please answer a question about the following article about Nonprofit organization:

The nonprofit landscape is highly varied, although many people have come to associate NPOs with charitable organizations. Although charities do comprise an often high profile or visible aspect of the sector, there are many other types of nonprofits. Overall, they tend to be either member-serving or community-serving. Member-serving organizations include mutual societies, cooperatives, trade unions, credit unions, industry associations, sports clubs, retired serviceman's clubs and peak bodies – organizations that benefit a particular group of people i.e. the members of the organization. Typically, community-serving organizations are focused on providing services to the community in general, either globally or locally: organizations delivering human services programs or projects, aid and development programs, medical research, education and health services, and so on. It could be argued many nonprofits sit across both camps, at least in terms of the impact they make. For example, the grassroots support group that provides a lifeline to those with a particular condition or disease could be deemed to be serving both its members (by directly supporting them) and the broader community (through the provision of a helping service for fellow citizens).
