The phrase “alternative stable state” in ecology refers to the tendency of many ecosystems to have different, stable configurations of biotic and abiotic conditions across large time scales separated by what are called regime or phase shifts. Alternative stable state theory claims that instead of a forest transitioning slowly along a gradient toward a different stable state, that forest will reach a crucial tipping point (known as an ecological threshold) as deforestation occurs. Any change beyond this threshold will lead to a rapid change towards the second stable state of the biome in question, in this case a grassland.

Ecologists typically describe this theory with an analogy: Picture a set of three hills, between which are two valleys with a ball sitting in one of them that you want to push into the other. \ If you don’t push enough, the ball just rolls back down to where it started, but if you give the ball a big enough push, it will roll all the way into the valley on the other side of the hill. From there, it would require a similarly big push to get the ball back to where it started. Stable states are the valleys – where the balls want to stay if no outside forces are involved. However, if there is a big enough change in the environment to cause the ball to roll all the way up the hill to its highest point (the ecological threshold), the ball can be forced from one valley into another relatively quickly – this is a phase shift.

Until recently, most work discussing alternative stable states was theoretical – the idea of purposefully changing an environment to this extent was considered unthinkable – but several cases of confirmed alternative stable states have been reported. For example, disrupting the balance of phosphorous in a clearwater lake can lead to out-of-control phytoplankton blooms. Reducing this addition of phosphorous has so far not been an effective way of stopping the phytoplankton blooms, leading researchers to think that the ecosystem has been pushed into a new local equilibrium. This idea of hysteresis – that the state of an environment depends at least in part on its history and not just its current state – is at the core of many debates surrounding alternative stable state theory. However, whether most ecosystems that can exist under multiple stable states will readily convert between the two is still an open debate.

Which of the following is confirmed in the passage as causing a phase shift in the environment?

Feminist literary criticism is literary criticism informed by feminist theory, or more broadly by the politics of feminism. Its history has been widespread and varied, from classic works of nineteenth-century women authors such as George Eliot and Margaret Fuller, to cutting-edge theoretical work in women's studies and gender studies by "third-wave" authors. In the most general and simple terms, feminist literary criticism before the 1970s—in the first and second waves of feminism—was concerned with the politics of women's authorship and the representation of women's condition within literature, including the depiction of fictional female characters. In addition, feminist criticism was further concerned with the exclusion of women from the western literary canon – an exclusion that most feminist critics suggest is due to the views of women authors not being considered universal.

Since the development of more complex conceptions of gender and subjectivity and third-wave feminism, modern feminist literary criticism has taken a variety of new routes, namely in the tradition of the Frankfurt School's critical theory. It has considered gender in the terms of Freudian and Lacanian psychoanalysis, as part of the deconstruction of existing relations of power, and as a concrete political investment. It has also been closely associated with the birth and growth of gay studies. The more traditionally central feminist concern with the representation and politics of women's lives has continued to play an active role in criticism. More specifically, modern feminist criticism deals with those issues related to the patriarchal programming within key aspects of society including education, politics, and the work force.

Recently, Lisa Tuttle has defined feminist theory as asking "new questions of old texts." Consequently she cites the following as the primary goals of feminist criticism: \ to uncover a female tradition of writing; to interpret symbolism of women's writing so that it will not be lost or ignored by the male point of view; to analyze women writers and their writings from a female perspective; to examine sexism in literature; and to increase awareness of the sexual politics of language and style. Only through such analysis, she argues, can a proper view of feminist criticism be framed moving forward.

According to the passage, all of the following would likely be a concern for feminist critics during the first and second waves of feminism EXCEPT:

According to the passage, all of the following are considered new routes of modern feminist literary criticism EXCEPT:

In day-to-day functioning, people rely on both memory and knowledge of that memory, referred to as metamemory. For example, a person often cannot immediately recall a name upon meeting someone, but they feel that they know it. This feeling is the result of monitoring memory. Because of this feeling-of-knowing (FOK), most people will continue to search their memory for this name. Once a name is generated, people then monitor and decide if they are confident enough to use that name.

Memory monitoring involves evaluating the ongoing progress of any aspect of memory. Experiments that evaluate memory monitoring typically have individuals make subjective judgments about their memory at various stages of learning and recall. Participants are asked a series of questions. After each question that they answer, they are asked to provide a retrospective confidence (RC) judgment, rating the likelihood that their response is accurate. When participants do not answer a question, they are asked for their prospective FOK judgment, assessing whether they nonetheless feel they do know the answer (for example because they think they may be able to remember it at some point in the future).

Perhaps predictably, RC judgments are highly correlated with actual knowledge of a topic. FOK judgments, however, correlate rather weakly—albeit positively—with actual knowledge. While there are some instances where the FOK is the result of a momentary inability to recall something, more often than not the FOK stems from the sense that one should know something, for example because the field is familiar.

Research has resulted in a general consensus that, when monitoring memory, individuals infer whether a particular response will be, or has been, remembered based on the inputs that are readily available. However, the particular inputs used differ depending on when memory is assessed. Prospective FOK judgments are thought to be based on familiarity of the cue, accessibility of information about the memory, or a combination of the two. In contrast, it is widely accepted that RC judgments are based on the memory-retrieval experience—that is, the “on-line” experience of directly retrieving some previously studied item.

According to the passage, FOK judgments and RC judgments differ in all of the following ways EXCEPT that

Based on the information in the passage, in which of the following situations would a RC judgment occur?

In 2004, Jared Diamond published Collapse, a rigorous analysis of why certain ancient societies have perished. His groundbreaking study explored the environmental and historical factors that contributed to the demise of the “Viking colonies” of Greenland, the Polynesians of Easter Island, and the Anasazi of the American southwest. Diamond’s core thesis was that human recklessness and lack of foresight were the major factors in precipitating the ends of these societies. 

Diamond’s work was among the first to seek out the commonalities between deforestation in Easter Island and resource depletion in ancient Greenland. Because he posited that human agency played a key role in determining whether cultures disintegrate or thrive, his message was viewed by many prominent environmental activists as a call to action – societies can remain vibrant providing they make prudent decisions regarding resource management.

However, many critics have claimed that Diamond’s explanations for the extinctions of ancient societies were simplistic, and placed undue blame on the regions’ inhabitants. For example, Terry Hunt, an archaeologist at the University of Hawaii, has claimed that the Polynesian deforestation, which Diamond attributed to the recklessness of the native peoples, was actually caused by predatory rats. Moreover, Hunt has noted that Diamond overlooked the role that European disease played in decimating native populations. If these other factors are taken into account, the issue of blame becomes a far more complex one and some of Diamond’s positions may need to be reconsidered.

According to the passage, all of the following were used by Diamond or Hunt to support their positions EXCEPT:
