Step-by-Step Solution
Solution:
Step 1: Analyze method body lines
The method has two lines: first creates a string but does not return it explicitly; second line is the number 42.Step 2: Identify returned value
Ruby returns the last evaluated expression, which is 42.Final Answer:
42 -> Option CQuick Check:
Last line value returned = 42 [OK]
Quick Trick: Method returns last line value, not earlier lines [OK]
Common Mistakes:
- Assuming first string line is returned
- Confusing puts output with return value
- Expecting nil because no explicit return
