The following passages concern a plant called purple loosestrife.

Topic

The ecological and sociological perspectives on the spread and control of purple loosestrife, an invasive wetland plant.

Framework

Present Debate

Main Point

The two passages offer contrasting views: Passage A (science perspective) focuses on the negative ecological impact of purple loosestrife and emphasizes the need for scientific control, while Passage B (sociological perspective) challenges the framing of loosestrife as purely an environmental threat and suggests that social/economic motivations underlie the push for its control. *Most Valuable Sentences:* - Passage A: (end of Passage A) - Passage B: (end of Passage B)

P1 (Passage A): Description of Invasion and Impact

This paragraph introduces purple loosestrife as a highly invasive species with a big negative impact on native wetland plants and possibly wildlife. It discusses how hard it is to control, describes failed and limited management efforts, and notes that research on long-term solutions is lacking.

P2 (Passage A): Call for Action & Control Methods

Here, the scientific report urges the need for integrated management and stresses that early intervention is key to minimizing ecological damage.

P1 (Passage B): Critique of the “War” on Loosestrife

The sociological voice jumps in here, calling out how loosestrife control is justified as an environmental crusade. The paragraph suggests that the framing is as much about the cultural story we tell (nature vs. invasive weed) as it is about real environmental danger.

13.

Which one of the following, if true, would cast doubt on the argument in passage B but bolster the argument in passage A?

  1. Correct

    Localized population reduction is often

    Why this is right

    This definitely helps us argue that purple loosestrife is scary and should be stopped. Passage B was downplaying the risk by saying that the impact of purple loosestrife has been pretty minimal so far. Only the canvasback has been identified as endangered by purple loosestrife. It may be negatively impacting furbearing mammals, but none of them can be considered threatened in North America. This answer is saying, "sure, it's not dire yet across the whole North American continent, but a local population reduction often comes just before widespread endangerment of a species. So if we do nothing than pretty soon this local population reduction could balloon into widespread endangerment." This helps A's alarmist point of view.

  2. Purple loosestrife was barely noticed

    Strengthens Passage B

    Because this sounds like it's downplaying the severity of loosestrife (it was barely noticed), this answer is working more towards supporting B's position.

  3. The amount by which overall

    Strengthens Passage B

    This is saying that if loosestrife were to mess up some of the species that are hunted and trapped, it would significantly hurt the hunting industry. This strengthens B's position that the main reason people are being hysterically worried about loosestrife is because they're worried about losing out on revenues from hunting and trapping.

  4. Some environmentalists who advocate taking

    Strengthens Passage B

    Passage B claimed that "the scientific effort to liberate nature from purple loosestrife is still connected to its philosophical origin as an instrument to control nature to the satisfaction of human desires." This answer choice is supporting that point, because it's talking about people who are trying to eradicate loosestrife because of their philosophy of controlling nature.

    6% picked this

  5. Purple loosestrife has never become

    Strengthens Passage B

    Passage A wants to eradicate loosestrife before it becomes a problem. Passage B's position is that we don't need to worry about loosestrife, so this is supporting B by saying that "even where it grows naturally and no attempt is made to eradicate it, it's never become a problem."
