 ## Non-consecutive tokens
 
 Unlike other QA models, which can only extract consecutive tokens (because they predict the start and end of a sequence), this model can predict longer-range, non-consecutive sequences with an additional
-classifier head. For example, it can extract the two-line address as below:
+classifier head. For example, QA models often encounter this failure mode:
 
-![Two-line Address](./demo.png)
+### Before
+
+![Broken Address](./before.png)
+
+
+### After
+
+However this model is able to predict non-consecutive tokens and therefore the address correctly:
