West meadow

North marsh

Center lake

Solution

Step 1: Decode and Map the Passage

Part A: Create Passage Analysis Table

Text from Passage	Analysis
Environmental scientists studying bird populations in a wetland preserve used different monitoring methods to document species diversity.	What it says: Scientists used 2 methods to count bird species in wetland What it does: Introduces the research context and methodology What it is: Context/setup
Their survey data shows: [followed by data table]	What it says: Data table shows visual counts vs audio counts for 5 locations What it does: Presents the actual research data What it is: Evidence/data
The highest number of bird species identified through visual count surveys was recorded at the ______	What it says: Missing location that had highest visual count What it does: Sets up question requiring data analysis What it is: Incomplete statement

Part B: Provide Passage Architecture & Core Elements

Visual Structure Map:
[RESEARCH CONTEXT] → [DATA TABLE] → [INCOMPLETE CONCLUSION]

Main Point: Environmental scientists collected bird species data using two different survey methods across five wetland locations.

Argument Flow: The passage establishes that scientists used two monitoring methods to study bird diversity, presents their data in table format, then asks us to identify which location had the highest visual count results.

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

Let's look at the visual counts: North marsh (23), East pond (67), South creek (12), West meadow (45), Center lake (19)
East pond has 67, which is clearly the highest value

Answer Choices Explained

East pond

✓ Correct

East pond recorded 67 bird species through visual count surveys, which is the highest number in the visual count column

West meadow

✗ Incorrect

West meadow recorded 45 species through visual counts, which is the second-highest but still 22 species fewer than East pond

North marsh

✗ Incorrect

North marsh recorded 23 species through visual counts, which is less than half of East pond's count

Center lake

✗ Incorrect

Center lake recorded 19 species through visual counts, which is the second-lowest visual count in the table
