You can choose the types of questions you want to answer:
   Yes/No questions
   Which tree has this characteristic?
   Which characteristic does this tree have?
   For these two characteristics, which tree has both?
   For these two trees, which characteristic is common to both?

You can select which characteristics you wish to be quizzed on:
  Needles per Cluster
  Single Needles
  Length of Needles
  Flattened Needles
  Length of Cones
  Fruit
  Thorns
  Leaf Edges
  Leaf Arrangement on Twig
  Simple Leaves Only
  Compound Leaves Only

You can choose what types of trees you would like to be quizzed on, as a group. Checking a characteristic in a group means trees in that group will be used for making questions. If you check a number of characteristics in one group (e.g. Needles per Cluster), trees with either of those characteristics will be part of the group (not just trees with both characteristics). If you check characteristics in different groups, the set of trees for each separate group is found, then trees that are common to all sets are used. Technically, within a group it's "characteristics OR char. OR char." and overall it's "group AND group AND group".

Yes, this all sounds confusing, but the idea is that you can choose to be tested on trees that have in common two or more specific sets of characteristics from different groups. For example, if this program were for house types, there might be two groups, Number of Stories and Exterior Wall Material. You could pick the characteristic "one-story" from the first group, and "stucco" and "brick" from the second, and the group of all houses used would then be "one-story AND (either stucco OR brick)". Try it out and see.
