### Canonicalized Input Description:

An integer N (1 ≤ N ≤ 10^3), representing some quantity or size.
A list of tuples P of size N, where each tuple consists of two integers x and y (−10^4 ≤ x, y ≤ 10^4), representing some coordinates or points.
A list of M tuples B, each of size K, where each tuple consists of K pairs of integers (x, y) (−10^4 ≤ x, y ≤ 10^4), representing some polygons.

### Example Input:

```
3
2 3
-1 4
5 6
2
4
1 2
2 3
3 4

### Function Signature:
Write a function f(N, P, B) that takes in the input.
```python
def f(N: int, P: List[Tuple[int, int]], B: List[List[Tuple[int, int]]]):
    '''
    N: an integer
    P: a list of tuples, each containing two integers
    B: a list of lists, each containing tuples of two integers
    '''
