  • Question 1
    • Examine the following Ruby code snippet that utilizes refinements:

      module LengthConversion refine String do def to_meters self.to_f / 3.281 end endend class MeasurementConverter using LengthConversion  def convert_to_meters(length_in_feet) length_in_feet.to_meters endend converter = MeasurementConverter.newoutside_conversion = "10".to_meters result1 = converter.convert_to_meters("10")result2 = outside_conversion What will be the values of result1 and result2, respectively?

      Answer: C
  • Question 2
    • Examine the following Ruby code snippet:

      a = 2
      b = 3
      c = '4'
      result1 = a * b
      result2 = a * c
      result3 = c * b
      result4 = c + a

      Answer: B
  • Question 3
    • Consider the following Ruby code snippet that incorporates the use of refinements:

      module StringAdjustments refine String do def emphasize "#{self}!" end endend class Writer using StringAdjustments  def emphasize_statement(statement) statement.emphasize endend writer = Writer.newexternal_statement = "Hello".emphasize result1 = writer.emphasize_statement("Hello")result2 = external_statement What will be the values of result1 and result2, respectively?

      Answer: C
  • Question 4
    • Consider the following Ruby code snippet involving the implementation and usage of the Comparable module:

      class TimeRange include Comparable  attr_reader :start_time, :end_time  def initialize(start_time, end_time) @start_time = start_time @end_time = end_time end  def (other) return nil unless other.is_a?(TimeRange) [start_time, end_time] [other.start_time, other.end_time] endend time_range1 = TimeRange.new(10, 20)time_range2 = TimeRange.new(15, 25)time_range3 = TimeRange.new(10, 20) result1 = time_range1 time_range3  What will be the values of result1, result2, and result3, respectively?

      Answer: B
  • Question 5
    • In Ruby, the understanding of operators and their precedence is crucial for writing correct and efficient code. Consider the following Ruby code snippet:

      a = 10b = 3result1 = a + b * 2result2 = (a + b) % 3result3 = a ** b / 2 Based on this code, which two of the following statements are true regarding the use of operators and their precedence?

      Answer: A,E
