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?

Analyze the following Ruby code snippet that utilizes regular expressions for string processing:class EmailExtractor EMAIL_REGEX = /(\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b)/  def self.extract_from(text) text.scan(EMAIL_REGEX).flatten endend text1 = "Contact us at support@example.com for assistance"text2 = "Send your feedback to: feedback@example.co.uk and admin@example.com"text3 = "No emails here!" result1 = EmailExtractor.extract_from(text1)result2 = EmailExtractor.extract_from(text2)result3 = EmailExtractor.extract_from(text3) What will be the values of result1, result2, and result3, respectively?

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?

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?

Evaluate the following Ruby code snippet that involves the forwardable and date modules:require 'forwardable'require 'date' class Project extend Forwardable def_delegators :@deadline, :month, :day  attr_accessor :name attr_reader :deadline  def initialize(name, deadline) @name = name @deadline = Date.parse(deadline) endend project = Project.new("Ruby Exam Prep", "2024-06-30")result1 = project.monthresult2 = project.dayproject.deadline = Date.parse("2024-07-15")result3 = project.month What will be the values of result1, result2, and result3, respectively?
