Difficulty: MediumLogical Inferences

To understand how regional dialects persist despite high geographic mobility, sociolinguist Elena Rostova analyzed lexical variation across two demographically similar towns: Oakhaven, which has a single major local employer, and Pineview, where the workforce commutes daily to a metropolitan center. Rostova hypothesized that towns with lower external labor integration maintain stronger local linguistic markers due to denser local social networks. Her survey revealed that Oakhaven residents used traditional regional terms at a rate nearly three times higher than Pineview residents did, and that Oakhaven residents reported significantly more social interactions confined entirely within town borders. _______

Which choice most logically completes the text?

  1. A
    These findings show that geographic mobility is the primary determinant of all dialect variations across different towns.
  2. These findings support Rostova's hypothesis by suggesting that local social networks, when bounded by limited external labor commute, play a critical role in preserving regional lexical features.Answer
  3. C
    These findings indicate that Oakhaven residents frequently travel to metropolitan centers but deliberately choose to avoid modern lexical terms.
  4. D
    These findings imply that introducing new local employers in Pineview would immediately cause its residents to adopt Oakhaven's dialect.

Answer

These findings support Rostova's hypothesis by suggesting that local social networks, when bounded by limited external labor commute, play a critical role in preserving regional lexical features.
The correct answer logically completes the text because it directly connects the empirical evidence (Oakhaven's lower commuting rates, denser local social interactions, and high rate of traditional term usage) to Rostova's hypothesis that lower external labor integration preserves regional dialects by fostering dense, local social networks.

Step-by-Step Solution

1
Identify the primary hypothesis and variables studied.
Rostova's hypothesis is that lower external labor integration preserves local dialects by keeping social networks dense and localized.
Understanding the core claim helps determine what conclusion would validate or invalidate it.
2
Analyze the empirical findings for both towns.
Oakhaven has lower commuting, denser local social interactions, and three times higher usage of traditional terms compared to Pineview.
Evaluating the data allows us to see how it aligns with the initial hypothesis.
3
Select the option that logically connects the findings to the hypothesis without making unsupported assumptions.
The findings show a direct correlation between localized networks (due to lack of commuting) and dialect preservation, supporting the hypothesis.
A logical inference must be directly supported by the premises without introducing external speculation.
