Creating rules so that certain answers prompt a unique set of questions

Hi,

Looking for some help . What I want to do is make the next question conditional upon their answer as opposed to the next answer (the current conditional functionality as I understand it.)

For example, If they pick the answer 'dismantle lift' over the other options then they are prompted to answer an additional question which is unnecessary for the other answer options.
Any help would be appreciated.
