1 Michael在报纸上登了一则广告：“最新宝马出售，只要1200000，感兴趣人士请打123456.” 之后，Alan打电话问Michael：“我想1000000买了这辆车。”Michael说：“我不能接受低于1100000的价钱，但是我星期六之前不会卖给任何人，如果你想要这辆车就打电话给我一个回复。”

星期三的时候，Alan打电话给Michael但是没人接，于是他留了一个message到Michael的答录机上说：“I accept your offer.”但是Michael的儿子不小心山删掉了这条信息，于是Michael未能听到这个口信。当天晚些时候，Michael把宝马车以1200000的价格卖给了另外一个人。

问题：Michael和Alan之间有没有合约的存在？（从offer（邀约），acceptance（接受）和consideration（代价）方面说明）

2 一个女生想买一台可以兼容ibm软件的电脑，可是她对电脑一窍不通，所以她去了一家店问店员哪种电脑是可以兼容的，店员告诉她“super fast”系列电脑可以兼容，于是她就买了。但是事实上这个店员不小心把“super fast”和“swist fast”两种系列的电脑的名字给搞乱了，真正可以兼容的应该是“swist fast”。那个女生在买电脑的时候顺便还买了ibm的一套软件，结果回到家的时候发现软件根本没法用，于是才知道这台电脑其实不可以兼容。

我的问题是，那个店员的行为是属于疏忽的失实陈述还是属于无辜的失事陈述，还是属于其他的？？那个女生可以不可以得到补偿？

因为题目是英语的，我给翻译了下，怕自己翻译的不够准确之类的，附上英文原题，望各位高手鼎力相助！！！！！多谢！！！！
1 Michael owns a car company in Causeway which mainly sells first hand BMW.
On Monday, he places an item in the advertisement column of the Apple Daily: “Brand-new BMW735i for sale, full option, HK$1,200,000 only, interested party please call 9012XXXX Michael”.

Later that day, Alan, a car lover, phones Michael and says, “the BMW735i for sale, I’ll take it for HK$1,000,000.”
Michael replies, “I cannot accept less than HK$1,100,000 but I will not sell it to anyone else before Saturday.
Let me have a reply by phone by Friday if you want it.”

On Wednesday, Alan phones Michael and leaves a message on his answering machine stating “I accept your offer”.
Unfortunately, Michael’s naughty son later presses a button on the machine which deletes the message before Michael listens to the recording.
Later that day Michael sells the BMW735i to Candy for HK$1,200,000.

Mabel is planning to buy an IBM notebook computer but she knows very little about computer.
She visits David’s Computer Shop to choose a computer compatible with IBM software.
David tells her that the series “Super Fast” is a fast computer and that Mabel can use IBM software with it.

David indeed makes a mistake unintentionally and mixes up the series “Super Fast” with another series “Swift Fast” whereas “Swift Fast” is IBM software compatible but “Super Fast” is not.
Mabel buys the “Super Fast” series notebook computer following David’s recommendation since she would like to use an IBM software.
After the purchase, Mabel spends HK$100 to buy that IBM software.
Later on the same day, she discovers that the computer is running slow and is not IBM software compatible.
