Central Asia

Solution

Step 1: Decode and Map the Passage

Create Passage Analysis Table

Text from Passage	Analysis
'Linguistic researchers have undertaken extensive documentation efforts to preserve endangered languages worldwide.'	What it says: Researchers = documenting endangered langs globally What it does: Introduces the research context What it is: Background context
'Based on the data, the region where documentation efforts achieved a success rate closest to 20 percent was ______'	What it says: Need region w/ ~20% success rate What it does: States the specific claim to complete What it is: Fill-in-the-blank statement
Data Table: Arctic regions - 12.67%	What it says: Arctic = 12.67% What it does: Provides specific data point What it is: Evidence/data
Data Table: Pacific islands - 28.34%	What it says: Pacific = 28.34% What it does: Provides specific data point What it is: Evidence/data
Data Table: Amazon basin - 35.91%	What it says: Amazon = 35.91% What it does: Provides specific data point What it is: Evidence/data
Data Table: Central Asia - 19.28%	What it says: C. Asia = 19.28% What it does: Provides specific data point What it is: Evidence/data
Data Table: Sub-Saharan Africa - 24.15%	What it says: Sub-Saharan = 24.15% What it does: Provides specific data point What it is: Evidence/data

Provide Passage Architecture & Core Elements

Main Point: Researchers are documenting endangered languages with varying success rates across different geographic regions, and we need to identify which region achieved closest to 20% success.

Argument Flow: The content establishes that extensive language documentation efforts are happening globally, then presents an incomplete statement about which region achieved roughly 20% success, followed by specific percentage data for five different regions that allows us to complete the statement.

Step 2: Interpret the Question Precisely

This is a fill-in-the-blank question asking us to choose the best logical connector. The answer must create the right relationship between what comes before and after the blank.

Step 3: Prethink the Answer

We need to calculate which percentage in the table has the smallest difference from 20%
This requires finding the absolute difference between each region's percentage and 20%
The region with the smallest gap (whether above or below 20%) will be our answer

Answer Choices Explained

Arctic regions

Arctic regions
✗ Incorrect

Arctic regions achieved 12.67% success rate
Difference from 20%: \(|20 - 12.67| = 7.33\) percentage points
While this is relatively close, it's not the closest option available

Pacific islands

Pacific islands
✗ Incorrect

Pacific islands achieved 28.34% success rate
Difference from 20%: \(|20 - 28.34| = 8.34\) percentage points
This is farther from 20% than some other regions in the table

Sub-Saharan Africa

Sub-Saharan Africa
✗ Incorrect

Sub-Saharan Africa achieved 24.15% success rate
Difference from 20%: \(|20 - 24.15| = 4.15\) percentage points
Closer than choices A and B, but still not the closest available

Central Asia

Central Asia
✓ Correct

Central Asia achieved 19.28% success rate
Difference from 20%: \(|20 - 19.28| = 0.72\) percentage points
This represents the smallest gap from 20% among all regions listed
