DO NOT MERGE
Please check.
Not really a big deal but I'd rather this be:
```ruby
(1..100).each do |user_id|
    5.times do |m|
        title = Faker::Lorem.sentence(6)
        content = Faker::Lorem.paragraph
        Answer.create!(title: title,
                       content: content,
                       user_id: user_id)
        puts "user #{user_id} posted: #{title}"
     end
 end
```


or 

```ruby
 (1..100).each do |n|
    5.times do |m|
        title = Faker::Lorem.sentence(6)
        content = Faker::Lorem.paragraph
        Answer.create!(title: title,
                       content: content,
                       user_id: n)
        puts "user #{n} posted: #{title}"
     end
 end
```

I prefer the first way since it tells you that you are repeating 100 times for each user but using both variables `n` and `user_id` seems kind of pointless imo
