The Romans have set up a transport service linking the five centres of Emmaus, Jerusalem, Bethlehem, Hebron and Masada. Each of the roads EJ, EB, EH, JB, BH, JM and HM is served in one direction only and by just one of the four animals Ass, Colt, Donkey and Mule. For example, you could ride from E to J, but I won’t say by which animal.
For his birthday, Jesus has been given a voucher which he has just used to make three tours by animal, each tour starting at E and finishing at M. The animals he rode were, in order, as follows (unfortunately I have forgotten the last animal on each journey).
1. A, C, M, C, D, M, ?.
2. D, A, C, D, A, C, A, ?.
3. D, M, C, M, C, A, ?.
In which direction can you journey between Bethlehem and Hebron and on which animal?
