Topic: Social Science


Paragraph 1

  • Paragraph note
    • Author's correction: New evidence shows that Indus Valley was an unparalleled civilization
  • Views, minor Meta-Structures, and the author's attitude
    • Old belief: Indus Valley was archaeologically uninteresting because it had typical architecture and no palaces or citadels (last sentence)
    • Author's correction: Recent excavations show Indus Valley had a combination of characteristics not present in any other civilization (last sentence)
    • Comparison of Indus Valley to other Bronze Age civilizations:
      • Geographically, it was a larger urban civilization than Egypt or Sumer (first and second sentence)

    • List of Indus Valley's achievements:
      • Brick cities on flood-proof terraces with long, straight streets (first sentence)
      • First urban sewer system (first sentence)
      • Possibly featured a democratic system of government (second sentence)
      • Thrived without armies (last sentence)

    • Author's attitude: "carefully organized" (first sentence), "top traders" (second sentence)

Paragraph 4

  • Paragraph note
    • Author's correction: Recent evidence suggests the decline of Indus Valley due to environmental reasons, not an invasion
  • Views, minor Meta-Structures, and the author's attitude
    • History books'/Wheeler's view: Indo-Aryan invaders led to Indus Valley's decline (second sentence)
    • Author's correction:
      • Lack of written or archaeological evidence supporting Wheeler's view (third sentence)
      • Excavations show Indo-Aryans weren't even present in the region at the time alleged invasion (fourth sentence)
      • Archaeological evidence shows relocation south of Indus Valley (fifth sentence)
      • Indus Valley people probably spread out into smaller cultures due to drought/food shortages or an earthquake (sixth through last sentence)
    • Cause-and-effect relationships:
      • Indo-Aryan invaders led to Indus Valley's decline, according to Wheeler and many history books (second sentence)
      • Drought could have caused lands to be unfarmable, which would cause an abandonment of city centers, according to the author (seventh through eighth sentence)
      • An earthquake could have caused rivers to change directions and caused migration to the country, according to the author (last sentence)
    • Author's attitude: "not certain" (first sentence), "lack of written evidence" (third sentence), "no archaeological evidence" (third sentence), "In fact" (fourth sentence), "most likely" (sixth sentence), "may" (seventh sentence), "may" (last sentence)

Main Point: New archaeological evidence reveals that the Indus Valley was an unparalleled ancient urban civilization and that its decline was more likely due to environmental changes, undermining previously held beliefs about the civilization.

Key Lines?

Paragraph 1, Sentence 3 (P1, S3) - Previously held belief and author's correction

P4, S2 - Previously held belief about the decline

P4, S6 - Author's correction about the decline

Meta-Structure?

Correcting the Record: This passage utilizes a Correcting the Record Meta-Structure*. In fact, the author corrects the record twice in this passage. First, the author corrects the mistaken belief that Indus Valley wasn't much to write home about. Over the second and third paragraphs, the author argues that new archaeological evidence shows that Indus Valley was an advanced, expansive, and productive civilization. Then, the author corrects another mistaken belief about Indus Valley's decline in the final paragraph. The author asserts that recent archaeological evidence undermines the long-standing view that an Indo-Aryan invasion led to the fall of the Indus Valley civilization. It's more likely, the author avers, that Indus Valley dispersed into smaller regional societies in response to some environmental change.

When a passage utilizes a Correcting the Record Meta-Structure and the author provides an alternative view to replace the mistaken one, the main point is usually the author's opinion about that alternative view. Unfortunately, the author never summarized their opinion about the new view on Indus Valley, so we'll have to piece together a summary for our author. We wrote that the main point is, "New archaeological evidence reveals that the Indus Valley was an unparalleled ancient urban civilization and that its decline was more likely due to environmental changes, undermining previously held beliefs about the civilization."

*Some may argue that this is a Criticizing a Viewpoint or Rebutting Critics Meta-Structure — understandably so, since there's considerable overlap between these Meta-Structures and the Correcting the Record Meta-Structure. If either of those designations makes more sense to you, then it's totally OK to go with either! Doing so will yield the same main point and broad understanding of the text we came up with by designating this passage a Correcting the Record Meta-Structure. Technically speaking, when the passage frames the view the author rebuts as misunderstood or ill-informed, it's best to consider the passage a Correcting the Record passage. The old view in this passage is ill-informed since those who held the old beliefs about Indus Valley didn't have access to the author's recent archaeological evidence. If the author otherwise argues another view is wrong, unjustified, or misguided, it's best to consider the passage a Criticizing a Viewpoint passage. And when the view the author rebuts is framed as a criticism, it's best to consider the passage a Rebutting Critics passage

List: The predominant minor Meta-Structure in this passage is a list. In the second and third paragraphs, the author list tons of reasons why the ancient Indus Valley civilization was impressive. We summarized each item on the list in the Passage Summary. If you'd like to save yourself some fact-finding missions on the inevitable Minor Point questions, you can try to memorize a few key items. Here's what we recommend memorizing about ancient Indus Valley:

  • Good city planners, with nice roads and sewage systems
  • Good at agriculture, particularly rice and cotton
  • Good at trading, getting as far as the Arabian Sea and Mesopotamia

Of course, if you have trouble memorizing stuff, you don't have to. You can always check the passage to anticipate what the correct answer will say. We'll discuss how you can do this most efficiently in the question explanations.

Last Thoughts?

The author expresses a lot of attitude in this passage. Way more than we usually see in social science passages. The author apparently admires the Indus Valley civilization for its accomplishments. The author seemingly doesn't care for Wheeler's ill-informed take on the Indus Valley civilization's decline. Because the author expresses this many opinions in this passage, expect at least a few Tone questions.

Strategy Overview

Review the main point, and use notes or highlighted/underlined text in the passage to recall the author's attitude, and find the answer that best reflects your understanding of the main point/author's attitude

Answer Anticipation

This question asks us about the author's view, but doesn't provide any insight into the topic of the correct answer or where the supporting information might show up in the passage. This means the correct answer is likely to relate back to the author's main point. As such, we'll need to rely on our big-picture understanding of the passage to answer this question. We should start by reminding ourselves of the main point (either by reviewing what we said after reading the passage or by rereading our answer to the main point question). We can also review any notes about the author's attitude or any text we highlighted because it expressed the author's opinion. After doing that, we can head to the answer choices, tabling those that don't line up with the main point. For those answer choices that conform to the author's main point, we'll use our notes and the passage to see if it's correct.The main point of the passage was, "New archaeological evidence reveals that the Indus Valley was an unparalleled ancient urban civilization and that its decline was more likely due to environmental changes, undermining previously held beliefs about the civilization." It's not efficient to review the author's view on each of the Indus Valley's many accomplishments. Instead, we can just recall that the author seems quite impressed by those achievements. Regarding Indus Valley's decline, the author definitely isn't buying Wheeler's theory and seems pretty convinced the decline was due to catastrophic environmental changes, like a drought or earthquake (P4, S6-9). But we should also recall that the author claims "the causes of the civilization's decline ... are not certain" (P4, S1). So, the author probably hasn't committed to any single explanation for Indus Valley's decline.

Answer choices

  1. A
    Because the Indus Valley Remaining source text redacted.
    Why choice A is not credited

    (A) Is this consistent with the passage's main point and what we reviewed from the author's attitude?

    Not really. This answer choice says that the author prefers the earthquake explanation for Indus Valley's decline. That doesn't comport with the author's claims that "the causes of the civilization's decline ... are not certain" (P4, S1). And if we reviewed the passage, we'd see that the author says that an earthquake "may have" led to geological changes that spurred a mass relocation of Indus Valley denizens (P4, S9). That "may" is not a strong enough assertion to conclude that the author thinks the earthquake explanation is "most likely."

  2. B
    Only a disaster as Remaining source text redacted.
    Why choice B is not credited

    (B) Is this consistent with the passage's main point and what we reviewed from the author's attitude?

    No. Even more than (A), this answer choice suggests the author went all-in on the earthquake explanation. That's not supported by the passage. The author says, "the causes of the civilization's decline ... are not certain" (P4, S1), suggesting they may be open to non-catastrophic-environmental-change explanations. The author also says that "severe drought," which may not be "as catastrophic as an earthquake," could have led to Indus Valley's decline (P4, S7).

  3. C
    Archaeologists' understanding of the Remaining source text redacted.
    Why choice C matches the stem

    (C) Is this consistent with the passage's main point and what we reviewed from the author's attitude?

    Yes, this seems to be consistent with the author's belief that catastrophic environmental changes, like a drought or earthquake, led to Indus Valley's the decline (P4, S6-9). Of course, the author hasn't committed to any specific explanation (P4, S1). So, it's reasonable to assume that the author would want archaeologists to search for signs of earthquake damage in the former Indus Valley cities. Doing so would either provide evidence for or against a theory the author thinks is plausible. Decisive and experienced test-takers would likely select this without reviewing the passage.

    If we did review the passage, we'd find even more reasons to select (C). The author says Indus Valley is a "seismically volatile region" (P4, S9) but doesn't say there's evidence of an actual earthquake near the time the civilization fell. On the other hand, there is evidence of severe drought (P4, S7). So, searching for signs of earthquake damage would either support the earthquake explanation (if such evidence is found) or the severe drought explanation (if no such evidence is discovered).

  4. D
    The cities of the Remaining source text redacted.
    Why choice D is not credited

    (D) Is this consistent with the passage's main point and what we reviewed from the author's attitude?

    No. For that reason, savvy test-takers would table or eliminate (D) without checking the passage.

    Besides, we wouldn't find any evidence to support (D) even if we reread the entire passage. The author never says the cities in the Indus Valley civilization should have been better prepared for major earthquakes. The author never even says an earthquake definitely led to the demise of the Indus Valley civilization.

  5. E
    The demise of the Remaining source text redacted.
    Why choice E is not credited

    (E) Is this consistent with the passage's main point and what we reviewed from the author's attitude?

    Nope. Once again, this answer choice implies that the author went all-in on the earthquake explanation (which involves altering major rivers' courses, see P4, S9). That's not consistent with the author's assertion that "the causes of the civilization's decline ... are not certain" (P4, S1) or the claim says that an earthquake "may have" led to the end of the Indus Valley civilization (P4, S9).
