Br Br for o Higher priority opposit side (E) Willigher Higher priority same side (2) ligher priority same side Hence (2)

OCR we cannot E ar z predict the a as no two group have different priority. Hente; l-E 4 - can't say wolom) boinhard 2-2 3-2 MOOV- a

We cannot predict E and Z for 4 as no two group are of different priorities.
