How to use multiple .each statements in ruby?

I want to do something like this,

for topic.sections.each do |section| and topic.questions.each do |question|
    print section
    print question
end

I want both sections and questions simultaneously, the output will be like this: section 1 question 1

section 2 question 2

I know what i did there is foolish, but, what is the exact way to do this or is this even possible?

Then do below with the help of Enumerable#zip:

topic.sections.zip(topic.questions) do |section,question|
    p section
    p question
end

Use Enumerable#zip.

For example,

sections = ['a', 'b', 'c']
questions = ['q1', 'q2', 'q3']
sections.zip(questions) { |section, question|
  p [section, question]
}

# => ["a", "q1"]
# => ["b", "q2"]
# => ["c", "q3"]
