Cultural Tip
In everyday Italian both 'cosa' and 'che cosa' are acceptable, but 'cosa' sounds slightly more informal. When speaking to someone you don't know well, you might prefer the more formal 'Qual è la causa di…'. Also, Italians often expect a brief explanation after the answer, so be ready to elaborate on the cause.
