n,q=map(int,input().split())

d=dict()

for i in range(n):

    s1,s2=map(str,input().split())

    d[s1]=s2
for j in range(q):
    s3=input();k=len(s3)

    if '.' in s3:

        j=s3[::-1].index('.')
        i=k-j-1
        value=s3[i+1:]
        if value in d:
            print(d[value])
        else:
            print('unknown')
