Which one of these lines is wrong?

2. If I have a query point P, and I’m trying to find the nearest neighbor, and I have two bounding boxes M and M’, which of the following conditions lets me ignore M?
MINDIST(P,M) > MINMAXDIST(P,M’)
MINDIST(P,M) < MINMAXDIST(P,M’)
MINDIST(P,M’) > MINMAXDIST(P,M)
MINDIST(P,M’) < MINMAXDIST(P,M)

3. If I have a query point P and a potential nearest neighbor O, and an MBR M which might have an even closer neighbor, which of the following conditions does not let me eliminate something?
||(P,O)|| > MINMAXDIST(P,M)
||(P,O)|| < MINDIST(P,M)
||(P,O)|| >
MINDIST(P,M’) > MINMAXDIST(P,M)
MINDIST(P,M’) < MINMAXDIST(P,M)
