The local police need someone who understands logical connectives (and, or, if...then, ...) to identify the correct suspect from the given clues.
Are you up to the task? Will you be our Connective Detective?
Connective | Common Form | Truth Value |
---|---|---|
not | It is not the case that [STATEMENT1] | This is true when [STATEMENT1] is false, and false when [STATEMENT1] is true. |
and | [STATEMENT1] and [STATEMENT2] | This is only true when both [STATEMENT1] and [STATEMENT2] are true. Otherwise this is false. |
or | [STATEMENT1] or [STATEMENT2] | This is only false when both [STATEMENT1] and [STATEMENT2] are false. Otherwise this is true. |
if, then | if [STATEMENT1] then [STATEMENT2] | This is only false when [STATEMENT1] is true but [STATEMENT2] is false. Otherwise this is true. |
if and only if | [STATEMENT1] if and only if [STATEMENT2] | This is only true when [STATEMENT1] and [STATEMENT2] have the same truth value (i.e, both statements are true or both statements are false). Otherwise it is false. |
For each case, you will be given a group of photos of the suspects. While looking over the suspects, you can:
Click on the CLUES button
to review the clues for the case (the statements
should be your main focus).
Swipe DOWN ➜ on a suspect to rule them out
Swipe UP ➜ on a suspect to accuse them (or to reconsider)
Double-click on a photo to zoom in
We just got into a lot of trouble for fingering the wrong suspect! You're being to hasty.
That was 0 strikes. Three more strikes and you're outta here!
Yes, that makes sense! We got our man.
Great job! How 'bout sticking around and helping us some more?
Sorry, kid. Detective work is a logic game, not a guessing game.
You solved all of our current cases! Great job, detective!
Thanks for all your help. See ya 'round!
