Question

Difficulty: MediumSupporting Claims with Evidence and Details

The following sentences are from a draft of an essay about dendrochronology. To ensure that the paragraph logically builds its claim that tree-ring dating is a highly precise historical tool, in what order should the sentences be placed?

  1. 1Dendrochronology, the scientific method of dating tree rings, provides historians with an incredibly precise timeline of environmental and human history.
  2. 2This high level of precision is achieved because trees grow a new ring each year, with the ring's width reflecting the weather conditions of that growing season.
  3. 3By comparing these distinctive patterns from old living trees with wood samples from historic buildings or archaeological sites, researchers construct a continuous regional timeline.
  4. 4For example, researchers recently used a multi-century oak chronology to determine that a wooden shipwreck off the coast of England was constructed in exactly 1248 CE.

Answer

The sentences should be ordered starting with the introduction to dendrochronology, followed by the explanation of how precision is achieved through ring growth, then the methodology of comparing patterns to build timelines, and finally the concrete example of the dated shipwreck.
The paragraph flows logically from a general definition and claim about precision, to the biological mechanism enabling that precision, to the archaeological application of the mechanism, and finally to a specific historical example demonstrating that precision in practice.

Step-by-Step Solution

1
Identify the introductory sentence.
The sentence introducing dendrochronology and claiming it provides a precise timeline must come first.
It establishes the subject matter and key claim of the paragraph.
2
Connect the claim of precision to its scientific cause.
The sentence explaining how 'This high level of precision is achieved' via annual ring growth must come second.
The demonstrative pronoun 'this' directly links to the 'incredibly precise' claim in the first sentence.
3
Identify the logical link to larger scale applications.
The sentence describing how 'these distinctive patterns' are compared to wood samples to build regional timelines must come third.
It refers back to the patterns mentioned in the second sentence and explains how researchers use them to construct timelines.
4
Find the concrete supporting evidence.
The sentence starting with 'For example' about the shipwreck must come last.
It provides a specific real-world example that supports the general claims of precision and archaeological timeline construction established in the first three sentences.
