Suggested answers for an English question in supplementary exercise

Mighty

如果没有前文後理、我敢説SUGGESTED　ANSWERS是錯的。
Q: Where do you buy jeans?
A: I buy jeans in a jeans shop.
Q: Where do you buy books?
A: I buy books in a bookshop.
Or you can use "jeans shops" and "bookshops" without any articles but is not so common.  用左”THE"、可能在説者＆聴者之間只有一間JEANS SHOP　OR　BOOK　SHOP。　本EXERCISE　BOOK可以掉得LA.　下下要考究対＆不対、父母辺有GUM多時間。　Time to look for a better one.
