[FIX] survey: fix demo data incoherence

Fix the demo user input lines which were considering "Pinaceae"
as a correct answer to the question "Dogwood is from which family
of trees ?" even though the suggested answer was declared as incorrect
for the question.
Dogwood is indeed from the "Cornaceae" family of trees, not the "Pinaceae".
Fixing the issue by updating the user input lines to be incorrect.
