B"You are given an array a consisting of n zeros. You are also given a set of m not necessarily different segments. Each segment is defined by two numbers l_i and r_i ( 1 <= l_i <= r_i <= n ) and represents a subarray a_{l_i}, a_{l_i+1}, ... , a_{r_i} of the array a . Let's call the segment l_i, r_i beautiful if the number of ones on this segment is strictly greater than the number of zeros. For example, if a = [1, 0, 1, 0, 1] , then the segment [1, 5] is beautiful (the number of ones is 3 , the number of zeros is 2 ), but the segment [3, 4] is not is beautiful (the number of ones is 1 , the number of zeros is 1 ). You also have q changes. For each change you are given the number 1 <= x <= n , which means that you must assign an element a_x the value 1 . You have to find the first change after which at least one of m given segments becomes beautiful, or report that none of them is beautiful after processing all q changes. The first line contains a single integer t ( 1 <= t <= 10^4 ) -- the number of test cases. The first line of each test case contains two integers n and m ( 1 <= m <= n <= 10^5 ) -- the size of the array a and the number of segments, respectively. Then there are m lines consisting of two numbers l_i and r_i ( 1 <= l_i <= r_i <= n ) --the boundaries of the segments. The next line contains an integer q ( 1 <= q <= n ) -- the number of changes. The following q lines each contain a single integer x ( 1 <= x <= n ) -- the index of the array element that needs to be set to 1 . It is guaranteed that indexes in queries are distinct. It is guaranteed that the sum of n for all test cases does not exceed 10^5 . For each test case, output one integer -- the minimum change number after which at least one of th"...
