This folder contains the tasks used in our 2nd experiment.

All files are XML files in the plist format (see http://en.wikipedia.org/wiki/Property_list).

Each plist file contains the 4 tasks that go with a particular dataset (see the dataset folder for the datasets). All 4 tasks are of the same type and consist in presenting three {country, year} pairs to the participant and ask/her to determine which one has the lowest value. Each task is a <dict> element in the plist file that encapsulates the following data:
- <key>question</key>: The question asked
- <key>answers</key>: The three possible answers
- <key>correct answer</key>: The right answer

Other elements in the plist file can be ignored.
 
Please see our CHI'2013 paper for more details.
