Given a sentence and a label in Croatian, select the correct answer. There are 2 choices given, out of which only one is correct for a given statement and label. The label of the task is either 'cause' or 'effect'. The output will be the choice which matches the label with the given statement. If the label is 'cause', then the choice which represents the reason of the statement, gives the answer. If the label is 'effect' then the choice which reflects the consequences of the statement is the answer. The output should be the text from the correct choice and not Choice1/Choice2.
One example: Statement: Žena je popravila svoju slavinu. 
Label: cause 
Choice 1: Slavina je curila. 
Choice 2: Slavina je bila zatvorena.
Solution is here: Slavina je curila.

Label: cause
Choice 1: Tvornice su povećale proizvodnju.
