Review the following Ruby code snippet:def divide_numbers(x, y) x / yrescue ZeroDivisionError => e puts "Error: #{e.message}"end result1 = divide_numbers(10, 2)result2 = divide_numbers(10, 0)result3 = begin divide_numbers(10, '5') rescue TypeError => e "Caught: #{e.class}" endresult4 = divide_numbers(10, nil) rescue "Invalid operation" What will be the values of result1, result2, result3, and result4, respectively?


Answer: D
Question 2

In Ruby, understanding non-local exits such as break, next, and return within the context of blocks and methods is crucial for controlling the flow of a program. Consider the following Ruby code snippet:def test_method [1, 2, 3].each do |i| return i if i == 2 end "No match"end result = test_method Based on this code, which two of the following statements are true regarding non-local exits in Ruby?

Answer: B
Question 4

Review the following Ruby code snippet:def divide_numbers(x, y) x / yrescue ZeroDivisionError => e puts "Error: #{e.message}"end result1 = divide_numbers(10, 2)result2 = divide_numbers(10, 0)result3 = begin divide_numbers(10, '5') rescue TypeError => e "Caught: #{e.class}" endresult4 = divide_numbers(10, nil) rescue "Invalid operation" What will be the values of result1, result2, result3, and result4, respectively?


Answer: D
