#include<stdio.h>

int main(void)
{
        int n,m,i,j,min,tmp,jj;

        scanf("%d%d",&n,&m);

        int a[n],b[n],c[m],d[m];

        for(i=0;i<n;i++)
                scanf("%d%d",&a[i],&b[i]);
        for(i=0;i<m;i++)
                scanf("%d%d",&c[i],&d[i]);

        for(i=0;i<n;i++){
                tmp = 10000000;
                for(j=0;j<m;j++){
                        if(c[j]>a[i])
                                min = c[j] - a[i];
                        else
                                min = a[i] -c[j];
                        if(d[j]>b[i])
                                min +=d[j] - b[i];
                        else
                                min +=b[i] - d[j];
                        if(tmp>min){
                                tmp = min;
                                jj = j+1;
                        }
                }
