A
1, 2 and 4
B
1, 3 and 5
C
2 and 4 only
D
3 and 5 only
Correct answer: (a) 1, 2 and 4
Explanation
- A
1, 2 and 4
1, 2 and 4. Italy, Japan and South Korea — low fertility / ageing.
- B
1, 3 and 5
1, 3 and 5. Nigeria and South Africa are not the usual ultra-low fertility set here.
- C
2 and 4 only
2 and 4 only. Drops Italy, which is in the ageing group.
- D
3 and 5 only
3 and 5 only. High-fertility / younger profiles, not the keyed set.
Summary. Official key is (a) 1, 2 and 4. Italy, Japan and South Korea are repeatedly in the news for very low birth rates and rapid ageing. Nigeria remains high-fertility; South Africa is not grouped with East-Asian / South-European ultra-low TFR in this paper. So 3 and 5 drop.
