counter-strike-12
Source: hackerearth
Difficulty: EASY

Navi is a counter strike pro. He always say how good he is at counter strike. After being tired of Navi, his friends decided to test his skills at shooting.  They put M targets on a X-Y plane, each target is denoted by (X, Y) where X is x-coordinate and Y is y-coordinate. His friends also gave him N locations on X-Y plane from where Navi can shoot the targets. Navi knows that he can shoot a target if 
 Manhattan distance   between his location and target is ≤ D. If Navi can shoot more than half of the targets (for odd values of M check  only for the integral part of half of M, say M = 3,  \frac{2}{3} = 1) only then his friends believe that he is a pro at counter strike otherwise he is not. 

Input

First line of input contains an integers T denoting the number of test cases. First line of each test case consists of three integers N, M and D separated by a space. Next N lines of each test case contains a pair of integers denoting the X -co-ordinate and Y - co-ordinate. Next M lines of each test case contains a pair of integers denoting X -co-ordinate and Y - co-ordinate of each of the target.

N is number of shooting locations for Navi.  
M is number of targets. 
D is shooting range of Navi. 

Output
For each test case , Print "YES" if he is a pro else "NO" (without quotes) .
Constraints
 1 ≤ T ≤ 6  
 1 ≤ N ≤ 1000  
 1 ≤ M ≤ 1000  
  -50000 ≤ X, Y ≤ 50000 
  0 ≤ D ≤ 50000 
SAMPLE INPUT
1
3 3 5
1 1
2 2
3 3
1 0
0 0
2 0

SAMPLE OUTPUT
YES

Explanation

First location is at  (1, 1)  , we can shot any of the given targets  from here so  count >  \frac{3}{2} , therefore YES.
