#include <bits/stdc++.h>

using namespace std;

int main()

{

    int n,m,f=0;

    cin>>n;

    vector<int> a;

    for(int i=0;i<n;i++){

        int x;

        cin>>x;

        a.push_back(x);

    }

    cin>>m;

    vector<int> b;

    for(int i=0;i<m;i++){

        int x;

        cin>>x;

        b.push_back(x);

    }

    vector<int> c;

    for(int i=0;i<n;i++){

        for(int j=0;j<m;j++){

            int h=a[i]+b[j];

            if(find(a.begin(),a.end(),h)==a.end()&&find(b.begin(),b.end(),h)==b.end()){

                cout<<a[i]<<' '<<b[j];

                f++;

                break;

            }

        }

        if(f) break;

    }

    return 0;
