请教各位老师：
昨天刷题时，有个题目的答说当句子用how much对数目进行提问时，假如回答是“什么都没”，就只可以用none，不可以用nothing。由于nothing只能作代词，none可以作数目词。
今天刷《21世纪英文报》的题，看到一篇文章讲的是宠物店的老板送了一只小狗给残疾男生，一分钱都没收。可是题目的选项如下图所示：
那是否就只能选nothing了呢？这类都是学校作业，不敢不搞了解。恳请老师们指点。
【1】How much对不可数名词数目提问，否定回答用none 一点也没。对价格提问，用价格回答。
|How much milk is there in the bottle?瓶子里有多少牛奶？
|None .一点也没。
|How much is the pen?这支钢笔多少钱？
|Five Yuan. 五元。
|How much is the hat?这顶帽子多少钱？
| nothing. 免费地/没烧钱。
|How much did it cosplayt you to buy this pen?买这支笔花了你多少钱?
|Nothing.没烧钱（省略回答）
|It cosplayt me nothing to buy this pen.买这支钢笔没烧钱。（完整回答）
【2】what对事物提问，否定回答，用nothing什么也没。
|What is in the box?盒子里有哪些？
|Nothing. 什么都没。
|What do you know about it？对于这件事你了解什么？
|I know nothing about it. 对于这件事，我什么都不了解。
【3】how many 对可数名词提问，否定回答用none 一个也没。
|How many books are there on the table? 桌上有多少本书？
|None. 一本也没。
|How many apples do you have?你有多少个苹果？
|None.一个也没。
备注:for nothing 表示“免费/不烧钱” 或者“无酬劳；毫无结果；白白地”
She is always trying to get something for nothing .她总想不劳而获。

访问被取消，所有些筹备工作都白费了。
What's wrong with you is that you think you can get something for nothing.
你的问题是你觉得自己可以不劳而获。

【4】who的疑问句的否定回答用“nobody 无人/无人”

|Nobody. 无人。

|Nobody. 无人/无人。
