Analyze this image of marbles and determine the exact count using this methodology:
1. Begin by identifying each unique marble one at a time. Assign each a number as you identify it.
2. Verify your result by counting with a different method. Start from the bottom-left corner and work row by row, from left to right.

What is the exact, verified number of marbles in this image?

Analyze the attached satellite image of a property with these specific steps:

1. Residence identification: Locate the primary residence on the property by looking for:
   - The largest roofed structure
   - Typical residential features (driveway connection, regular geometry)
   - Distinction from other structures (garages, sheds, pools)

2. Tree overhang analysis: Examine all trees near the primary residence:
   - Identify any trees whose canopy extends directly over any portion of the roof
   - Estimate the percentage of roof covered by overhanging branches (0-25%, 25-50%, 50-75%, 75%+)
   - Note particularly dense areas of overhang

3. Fire risk assessment: For any overhanging trees, evaluate:
   - Potential wildfire vulnerability (ember catch points, continuous fuel paths to structure)
   - Proximity to chimneys, vents, or other roof openings if visible
   - Areas where branches create a "bridge" between wildland vegetation and the structure

4. Defensible space identification: Assess the property's overall vegetative structure:
   - Identify if trees connect to form a continuous canopy over or near the home
   - Note any obvious fuel ladders (vegetation that can carry fire from ground to tree to roof)

5. Fire risk rating: Based on your analysis, assign a Fire Risk Rating from 1-4:
   - Rating 1 (Low Risk): No tree branches overhanging the roof, good defensible space around
   - Rating 2 (Moderate Risk): Minimal overhang (<25% of roof), some separation between tree canopies
   - Rating 3 (High Risk): Significant overhang (25-50% of roof), connected tree canopies, multiple points of vulnerability
   - Rating 4 (Severe Risk): Extensive overhang (>50% of roof), dense vegetation against structure

For each item above (1-5), write one sentence summarizing your findings, with your final response being the numerical rating.
