Question 1

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?

A : The return keyword in the block causes an exit from the each loop and returns 2 from the test_method.

B : The return keyword in the block causes the entire program to exit, assigning nil to result.

C : The result variable will be assigned the string "No match" because the each loop completes its iteration.

D : If i equals 2, the each loop is exited and the test_method returns "No match".

E : The return keyword inside the block exits the block and continues execution with the next line after the each loop.

Answer: A,E

Question 2

In Ruby programming, the correct use and understanding of operators is essential. Analyze the following Ruby code snippet:a = 8b = 4result1 = a != bresult2 = a & b == 4result3 = (a * 2) / b Based on this code, which two of the following statements are true regarding the use and precedence of the operators?

A : result2 is true as the bitwise AND (&) operation has higher precedence than the equality (==) operator.

B : result1 evaluates to true because != checks if a and b are not equal.

C : result1 is false since != is a strict inequality operator and a is greater than b.

D : In result2, the equality (==) operation is evaluated before the bitwise AND (&) operation.

E : result3 equals 4 because division (/) has higher precedence than multiplication (*).

Answer: B,D

Question 3

Analyze the following Ruby code snippet in the context of class design and instance variable management:class Book attr_reader :title, :author @@total_books = 0 def self.total_books @@total_books end def initialize(title, author) @title = title @author = author @@total_books += 1 endendclass Library attr_reader :books def initialize @books = [] end def add_book(book) @books

A : undefined method 'total_books' for Library:Class, undefined method 'total_books_in_library' for Library:Class

B : 2, undefined method 'total_books_in_library' for Library:Class

C : undefined method 'total_books' for Library:Class, 2

D : 2, 2

Answer: C

Question 4

In Ruby, which of the following literals correctly creates a Hash object with default values for undefined keys?

A : hash = { default: [] }

B : hash = Hash.new { |h, k| h[k] = [] }

C : hash = Hash[:default, 0]

D : hash = {}.default(0)

Answer: B

Question 5

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?

A : NoMethodError, NoMethodError

B : Approximately 3.048, Approximately 3.048

C : Approximately 3.048, NoMethodError

D : NoMethodError, Approximately 3.048

Answer: C
