```cpp
#include <bits/stdc++.h>
using namespace std;
int main(){
int n;
int a,b;
double x,y;
cin >> n >> a >> b;
x = b / (double)a;
for (int i = 0;i < n - 1;i ++){
cin >> a >> b;
y = (double)b / a;
if (y - x > 0.05)cout << "better" << endl;
else if(x - y > 0.05)cout << "worse" << endl;
else cout << "same" << endl;
}
}
