The ancient cliff dwellings of the ancient Puebloans in the

Question

The ancient cliff dwellings of the ancient Puebloans in the southwestern United States may have been constructed much more quickly than within the 150-year span previously supposed by scientists, significantly altering researchers' understanding of societal development in Native American cultures. Pueblo oral histories hold that during the mid-13th century, a tribal leader named White Shell Woman organized a coordinated movement of communities into cliff dwellings for protection and resource management. But archaeologists had been unable to scientifically confirm this rapid transition, in part because of limitations with traditional pottery dating methods.

Recently, researchers, knowing that tree rings form annual growth patterns, applied dendrochronology to wooden support beams collected from various cliff dwelling sites. The technique measures both early and late wood formation within each ring, providing precise annual markers of when trees were harvested for construction. Dates from the samples that best reflect cutting time—those with bark still present—ranged from 1248 to 1265 CE, suggesting there was intensive cliff dwelling construction during that period. Because, the researchers argue, these structures served as centers for food storage and resource distribution, the rapid construction likely indicates a significant shift in community organization.

The events described by Pueblo oral histories agree with these new dates, and the cliff dwellings provide tangible archaeological evidence that this sociopolitical shift happened within a single generation of Ancestral Puebloans. This compressed timeline suggests that environmental pressures and increased regional conflict accelerated the need for protective structures far more quickly than previously thought.   1

Q1)  Answer:  D 
paragraph 1 of the passage reads  "Pueblo oral histories hold that during the mid-13th century, a tribal leader named White Shell Woman organized a coordinated movement of communities into cliff dwellings for protection and resource management"

Also toward the end of paragraph 2  "because, the researchers argue, these structures served as centers for food storage and resource distribution, the rapid construction likely indicates a significant shift in community organization."

Therefore we are able to infer that the dwelling were definitely used for food and protection, but why? It must certainly be due to some outside factor which is causing this shift (i.e. maybe torrential rain and prolonged extreme weather conditions).

Note:   I was stuck between C and D but I believe D is a clearer inference because how does the use of dwellings for food storage indicate anticipated long-term occupation of the dwellings? Maybe it was short term use to protect against an external factor? Hence, I chose D.

Q2  Answer:  C 
I believe its C because the passage discuses the use of testing the trees rings (new method, not previously used) to provide a conclusion that debunks researchers initial theory and aids previous historical theories. Hence C.

I am not too confident about my answer choice for Q3 or particularly my reasoning but I went with C. I used a process of elimination.

Please let me know your thoughts!

I liked C for question 3

The passage states that dendrochronology measures early and late wood formation within tree rings to provide  precise annual markers of when trees were harvested.  This supports the inference that the analysis helps determine the  year the trees were cut. 
 
  A:  Incorrect. While the trees were likely used shortly after harvest, this is not directly stated or emphasized. 
  B:  Incorrect. The passage does not specify that the presence of bark indicates late growth season harvest. 
  D:  Incorrect. The passage does not discuss identifying specific locations where the trees were felled. 
  E:  Incorrect. The passage suggests that the presence of bark is useful for dating, but it does not state that only the outermost rings provide accurate information.

A. The wooden beams used in cliff dwelling construction were cut and used immediately after being harvested.  Eliminated  No menion of period between harvesting and use has been mentioned.
B. The presence of bark on the beams indicates that the trees were harvested during the late growth season.  Eliminated  The presence of bark only made for better specimen to conduct studies of age.
C. The analysis of early and late wood formation helps researchers determine the year the trees were cut.  Suitable  This can be inferred from "  The technique measures both early and late wood formation within each ring, providing precise annual markers of when trees were harvested for construction   "
