我讀econ,你問既係(CE 97-01)(CE 02-03) FROM PAST PAPER.
等我解釋俾你聽:
1.
A.錯, 因為有scarcity so we have to make choice但唔代表we made choice後scarcity會 冇左.
B. 錯,因為scarcity means the resources is insufficient to satisfy all unlimited human wants,B係話a goods is scarce if not everyone has it. insufficient to satisfy all unlimited human wants 唔等於 not everyone has it.
C.e題啱一半,如果佢講埋unlimited wants就全對.因為unlimited human wants同 limited resources 係相對的.
D. 啱,因為人人都scarcity 既問題.
2.(1)啱，因為佢自己住自己間屋，放棄左租出去既租金收入。
(2)錯,業權人要交差响,佢係咪都要俾,e題問題與opportunity cost無關.
(3)錯,Mr lee 買左層樓,無論佢住唔住,佢買樓既錢(cost)唔會冇左,因為層樓係佢既個cost重係度。
所以A係啱。

1.
A. 完全唔知佢講緊咩意思。(X)
B. 啱一半，啱唔哂，係唔係好都重緊要睇咩人可以有權做。唔可能掃地個有鎖匙開公司出納部夾萬，但係出納呀姐就無鎖匙囉。(X)
C. 完全無限制啲人，想做咩都得都叫做食蕉？(X)
D. 唔洗問，一睇就知E個係定侓。(O)
2.
(1)唔啱，因為佢自己住自己間房，題目無話佢劏房出租畀其他人，所以無租金收。
(2)業權人要交差响、地租都係稅嘅一種。
(3)買樓要供樓無錯。
所以得D係啱。
