You will be given a statement and two events in Croatian. The events are either something that can be caused by the statement, or they are something that might have caused the statement. If they can be consequences of the statement, answer with "effect", else answer with "cause".

Let me give you an example: Statement: Gurnuo sam klatno.
Choice 1: Usporilo se i stalo.
Choice 2: Zanjihalo se naprijed-nazad.
The answer to this example can be: effect
Here is why: The choices given are related to the effect that pushing the pendulum will cause. It will either slow down and stop or will be swayed back and forth.

Statement: Penjači su došli do vrha planine.
Choice 1: Naišli su na lavinu.
Choice 2: Čestitali su si međusobno.
Answer:
effect
