An increase in the price of petroleum will lead to a decrease in
A. the demand of mini-bus services
B. the supply of mini-bus services.
The answer is B. But I think choice A is also OK.
我覺得petroleum 係mini-bus services既complement. 2者要一齊用先有功效。
我書入面舉既例子係the price of new car increases will lead to the demand of petrol decreases. 其實係咪要話the minibus service 上升或下降 先會影響petroleum 唔可以話petroleum影響minibus services既demand?
ECON 唔明 救命ar!~~

✔ 最佳答案
簡單問問, 白米加價, 你是否就可以食少d飯?油價上升後, 除非你改乘地鐵, 或是「做步兵」, 又或者「踩單車」, 否則的話, 巴士, 小巴, 的士都會同時加價, 亦因此, 在人口沒有改變之下, 小巴的服務需求是不會減少的.
