Task: Question Answering
Input (English): Question: When we perform the triple test (alpha fetoprotein, human chorionic gonadotropin and unconjugated estriol) to pregnant women, the sensitivity and specificity against trisomy 21 (Down's syndrome) are 63 and 95% respectively. This means: 
 Options:  <1> The percentage of false negatives is 5%. <2> The percentage of false positives is 37%. <3> The Area Under the Curve (AUC) ROC would be 1. <4> The probability of not having trisomy 21 (S. Down) being the negative result is 95%. <5> The probability of having a positive test result with trisomy 21 (Down syndrome) is 63%.
Output (English): 5
