I don't know how to upload files in this forum but below is a text version.

'Actor1' can 'askQuestion'
'Actor2' can 'answerQuestion'
'answerQuestion' addresses 'askQuestion'
'Actor2' can 'askQuestion' also
'Actor1' can 'answerQuestion' too
'askQuestion' can be 'Abstract'
'askQuestion' can be 'Concrete' too

Hope this helps even though I don't think so. You should have Rational Unified Languauge bundle which can give you all these samples.

A use case diagrqam is represented by an "oval" as per the UML notation. The use case however is the action performed by the actor.

E.g in a course registration system, some of the use cases are
1. Register for courses
2. Select courses to teach
3. Request Course roster etc etc

The actors are Student, Professor, Registrar, Billing System
