Which of the following is not a method used by pressure groups to achieve their objectives?

The method that is not used by pressure groups to achieve their objectives is contesting for political positions. Pressure groups are organizations that seek to influence government policies and decisions without seeking to take political power themselves. They use various methods to achieve their objectives, such as employing lobbyists, embarking on demonstrations, and embarking on strikes and boycotts. Contesting for political positions, on the other hand, involves seeking political power through elections, which is a different approach from what pressure groups adopt. Pressure groups typically seek to influence policy from the outside, while political candidates seek to influence policy from within the government. Therefore, contesting for political positions is not a method used by pressure groups to achieve their objectives.
