Q:

Using loops within CSV export - Ruby

I'm trying to DRY up my code and wondering if many people have experience with CSV's and ruby.
My code is below. It works just... Its awful. 
I'm wondering if anyone has any ideas on how I could do the following:
1 - How could I use a loop rather than explicit 1..10 that I've done. I did try a few ways but couldn't get them to work with CSV. 
 2 - Is there a nicer way to do headers in CSV?
 3 - Any other ideas on how to make CSV code nicer?
I initially went with this
(1..10).each do |number| 
end 

However the csv system didn't like that one! It was thinking my end statements were incorrect however, I don't think this was the case. 
Here's my code. If you have any bright ideas you're awesome! Yes I know it's awful, just wondering how I could do it better!

A:

How's this?
...
job.employer.account_type,
'null',
'null',
*1.upto(10).flat_map {|i|
  jq = job.job_questions[i]
  [jq[:question], jq[:knockout], jq[:correct_answer]]
}
...
