Choose the correct words to complete the IT guy's overly dramatic email about the broken coffee machine.

Should any mechanical problems _____ with the new espresso maker, be warned that a lack of caffeine will _____ a terrible fury in the marketing department.

The correct answer is arise / arouse.

"Arise" is an intransitive verb meaning to happen or occur (problems arise). "Arouse" is a transitive verb meaning to awaken or evoke a feeling, and it requires a direct object (it will arouse a terrible fury).
