In the marathon, all the competing countries were from Africa, but not the usual runners, and maybe that caused all prognostics on the race results to be wrong:
1) Algeria will not win the gold, nor Botswana the silver.
2) Chad will win a medal, and Djibouti will not.
3) Djibouti and Egypt will both win medals.
4) Djibouti will not win the silver, nor Egypt the bronze.
5) Algeria will win a medal, and Chad will not.
Who won which of the medals?
(In reply to

If Djibouti doesn't get a medal, then Chad doesn't either (so (2) is false) and Algeria also doesn't (so (5) is false), but that leaves only two medal winners, so Djibouti must get a medal.
The rest is immediate:
- Because of (3), Egypt doesn't get a medal.
- Because of (4), Djibouti gets Silver.
- Because of (1), Algeria gets Gold.
- Because of (5), Chad must get a medal, so Chad gets Bronze.
