Which statement correctly identifies a progressive shift in dialects across a territory?

• A. A map of dialects across a region
• B. Shows a progressive shift in dialects across a territory
• C. A collection of dialect maps
• D. A catalog of dialect terms

Answer: (B)

Understanding how dialects vary across space relies on seeing a gradual change rather than a set of isolated regions. A statement that says it shows a progressive shift in dialects across a territory communicates that idea directly: as you move across the landscape, pronunciation, vocabulary, or other features transition smoothly from one variant to another, creating a geographic gradient. This is the hallmark of dialect geography, where maps reveal a continuum of features rather than sharp, discrete boundaries.

The other options describe maps or collections in broader terms, but they don’t explicitly express the idea of a gradual, spatial progression of dialect features across the territory.
