Hi, Mandy.
You could use branching to send people to the URL's as redirects.
To do this, set up three separate pages in your survey with the redirect to each of the URL's — one per page. The redirect is an Add actions => Redirect Browser.
It would be best to have your consent form and general info on the first page. If they do not consent, you could disqualify them and send them to a message thanking them for their time. To set up the disqualify, on the bottom of page one, Add actions => Advanced Page Jumping & Logic. Then add a rule to disqualify them if they answer 'No' to the consent.
Then add page 2 with a message thanking the respondent for giving his/her consent and asking them to click the Next button.
Then add page 3 and put the branching there. To set up branching, Add actions => Branch Survey (A / B / C Split Testing). Set up the branching to each of the 3 redirect pages (which are pages 4, 5 and 6)…and you're done!
