Consider the following pairs:Regions sometimes mentioned in news - Country1.Catalonia - Spain2.Crimea - Hungary3.Mindanao - Philippines4.Oromia - NigeriaWhich of the pairs given above are correctly matched?

1. A

   1, 2 and 3

   (a) 1, 2 and 3. Catalonia is in Spain and Mindanao in the Philippines, but Crimea is a peninsula of Ukraine (annexed by Russia in 2014), not Hungary. Pair 2 spoils this set. This option is not the key.

2. B

   3 and 4 only

   (b) 3 and 4 only. Mindanao–Philippines is right, but Oromia is a region of Ethiopia, not Nigeria. This option is not the key.

3. C

   1 and 3 only

   (c) 1 and 3 only. Catalonia–Spain and Mindanao–Philippines are correctly matched. Crimea is not Hungarian; Oromia is not Nigerian. Hence only 1 and 3. This option is the official key.

4. D

   2 and 4 only

   (d) 2 and 4 only. Both of those pairs are wrong. This option is not the key.

Summary. Official key is (c) 1 and 3 only. Catalonia is an autonomous community of Spain; Mindanao is the large southern island of the Philippines. Crimea belongs with Ukraine/Russia, not Hungary. Oromia is in Ethiopia, not Nigeria. The two correct region–country pairs are therefore 1 and 3. That is option (c).
