Suppose Singapore is endowed with 100 units of labour. With 1 unit of labour, it can produce either 1 computer or 10 cameras. The world relative price of computers in terms of cameras is 12. 

Determine Singapore’s comparative advantage.

相对优势不是要在两个国家间比较的吗？自己和自己比，怎么看呢？

这里singapore的comparative advantage是producing computer吗？

那他的the production-possibility curve 应该是怎样的呢？
