No super-easy way to do this, you'll have to position various <textbox> elements on a surveypage, in-between <caption> elements for the surrounding text.
<defaults>
/ canvasaspectratio = (4,3)
/ fontstyle = ("Arial", 2%)
</defaults>
<surveypage example>
/ questions = [1=cap1, tb1; 2=cap2, cap3; 3=tb2; 4=cap4]
/ showquestionnumbers = false
/ showpagenumbers = false
</surveypage>
<caption cap1>
/ caption = "The war is not meant to be "
/ position = (20%, 5%)
</caption>
<textbox tb1>
/ textboxsize = (15%, 2.5%)
/ position = (39%, 5%)
</textbox>
<caption cap2>
/ caption = ", it is"
/ position = (55%, 5%)
</caption>
<caption cap3>
/ caption = "meant to be "
/ position = (20%, 10%)
</caption>
<textbox tb2>
/ textboxsize = (15%, 2.5%)
/ position = (29%, 10%)
</textbox>
<caption cap4>
/ caption = ". Hierarchical society is "
/ position = (45%, 10%)
</caption>
etc.
