不理解为什么有5个数据WA了

#include <iostream>
using namespace std;
long long a[10005], b[10005], g[10005], k[10005]; 
int main() {
	int n;
	cin >> n;
	for (int i = 1; i <= n; i++) {
		cin >> a[i] >> b[i] >> g[i] >> k[i];
	}
	int x, y;
	cin >> x >> y;
	int ans = -1;
	for (int i = 1; i <= n; i++) {
		if ((a[i] <= x) && ((a[i] + g[i]) >= x) && (b[i] <= y) && (b[i] + g[i]) >= y)
			ans = i;
	}
	cout << ans << endl;
	return 0;
}
