Q: Passage: Mach argued that, in effect, the water experiment in an otherwise empty universe would remain flat. But if another object were introduced into this universe, perhaps a distant star, there would now be something relative to which the bucket could be seen as rotating. The water inside the bucket could possibly have a slight curve. To account for the curve that we observe, an increase in the number of objects in the universe also increases the curvature in the water. Mach argued that the momentum of an object, whether angular or linear, exists as a result of the sum of the effects of other objects in the universe (Mach's Principle). Question: Mach argued that the momentum of an object exists as a result of the sum of the effects of what?

A: effects of other objects in the universe

Q: Passage: Kenneth Gergen formulated additional classifications, which include the strategic manipulator, the pastiche personality, and the relational self. The strategic manipulator is a person who begins to regard all senses of identity merely as role-playing exercises, and who gradually becomes alienated from his or her social "self". The pastiche personality abandons all aspirations toward a true or "essential" identity, instead viewing social interactions as opportunities to play out, and hence become, the roles they play. Finally, the relational self is a perspective by which persons abandon all sense of exclusive self, and view all sense of identity in terms of social engagement with others. For Gergen, these strategies follow one another in phases, and they are linked to the increase in popularity of postmodern culture and the rise of telecommunications technology. Question: In what classification is a person who regards all experiences are role play and becomes alienated from his or her social self?

A: The strategic manipulator
