premise: Dave Ward, born 12 July 1959, is a British Trade Unionist and General Secretary of the Communication Workers’ Union (CWU), which was formed through the merger of the Union of Communication Workers and the National Communications Union in 1995. The CWU is the largest Trade Union in the United Kingdom for people working in the Postal and Telecommunications industry with over 200,000 members.
hypothesis: Trade Unions are good for zebras.
reason: Some zoo workers were represented by trade unions. Believe it or not, workers at the Baltimore Zoo were represented by the United Steelworkers of America. But not every zoo is represented by this kind of organization. Also, trade union members and their families go to zoos. Their attendance would, in fact, contribute to the welfare of zebras. But it is not true that zebras 100% need unions to survive. If every trade union in the world dissolved, it would not eliminate the zebra population.
