How do I get rid of *just* the question and *not* the multiple choices?

Hi everyone,
I wonder if you can help me:
I need to be able to get rid of *just* the text entry bit of a multiple choice question (the bit where you'd ordinarily put the question), but *not* the multiple choices. The reason for this is that I'm displaying pictures and I want more room on participants' screens for the pictures. So just hiding the question wouldn't help; I actually need the text entry bit to disappear so that it isn't using space. (The question is the same for every photo, so participants are told the question at the start; in case this sounds odd).
I've tried the following code (which I got from a few previous posts on the community--thanks so much to the people who put this up):
Qualtrics.SurveyEngine.addOnload(function() {
   jQuery("#"+this.questionId).hide()
});

But that just gets rid of everything: question and responses.
Does anyone have any thoughts on how I'd do this?

Thanks so much for your help in advance with this. All you wizards who help others out are magic.
