Difficulty: EasySelecting the Best Title

Dendrochronology is the scientific method of dating environmental events and archaeological artifacts by analyzing growth rings in trees. Each year, a tree adds a single layer of wood beneath its bark, with the thickness of the ring reflecting the climate and moisture conditions of that growing season. By comparing overlapping patterns of rings from living trees to preserved ancient timbers, researchers can build a continuous chronological record spanning thousands of years. This allows scientists to determine the exact year a historic wooden structure was built or when severe droughts struck a region.

Which of the following is the best title for this passage?

  1. A
    A Comprehensive History of Modern Archaeological Discoveries
  2. B
    How Annual Moisture Levels Affect Timber Ring Thickness
  3. Using Tree Rings to Date Historic Events and ArtifactsAnswer
  4. D
    Preserved Ancient Timbers and Historic Wooden Structures

Answer

Using Tree Rings to Date Historic Events and Artifacts
The correct title, 'Using Tree Rings to Date Historic Events and Artifacts,' directly summarizes the definition, process, and primary application of dendrochronology discussed throughout the passage.

Step-by-Step Solution

1
Identify the central topic and scope of the paragraph
The text defines dendrochronology and explains how analyzing growth rings allows researchers to date historical wooden objects and past environmental events.
An effective title must reflect the main idea of the entire passage rather than an isolated detail or an excessively broad topic.
2
Evaluate the answer choices against the central idea
The option highlighting the use of tree rings to date historic events and artifacts encompasses both the mechanism and the purpose described in the text.
Eliminating choices that are too broad, too narrow, or merely repeating keywords ensures the title matches the true scope.
