Which of the following describes a sub-revolutionary terrorist objective?

The correct answer identifies the objective of sub-revolutionary terrorism, which seeks to influence an unwilling government. Sub-revolutionary terrorists typically engage in acts designed to coerce a government to change its policies or practices, often when they believe the government does not represent the interests of a particular segment of the population. This could include pressing for social reforms, civil rights, or attention to specific political issues. The focus is on altering government actions rather than outright overthrowing the current regime, which distinguishes it from revolutionary objectives.

Supporting this, the other options represent different objectives: eliminating a rival group is more characteristic of inter-group conflicts rather than targeting a government, supporting the current regime contradicts the fundamental goal of sub-revolutionary terrorism, and while recruiting new members is a common tactic for many terrorist organizations, it is not specific to the sub-revolutionary objective of influencing governmental policies.
