If its message were confined merely to information-and that in itself would be difficult if not impossible to achieve,for even a detail such as the choice of the colour of a shirt is subtly persuasive-advertising would be so boring that no one would pay any antention.这句话中and that in itself would be difficult if not impossible to achieve,for even a detail such as the choice of the colour of a shirt is subtly persuasive是什么意思？分析一下句子结构

Answer 1

如果它（广告）传达的讯息只是局限于信息层面-并且假使没有做不到的，甚至是一个细节例如衬衫颜色的选择都将具有十分微妙的说服力，而这本身就很困难-广告就会变得很枯燥，以至于没有人会注意到它。

这句话的结构其实是if从句叠一个be+adj.+for+从句的结构，具体如下information -and that(指for后从句) in itself would be difficult (if not impossible to achieve,) for [even a detail (such as the choice of the colour of a shirt) is subtly persuasive]

Answer 2

其信息只被局限于信息这本身就很难，并不是不可能实现的，甚至为一个detail如在一件衬衫color choice巧妙地说服- advertising would是so无聊，没有人会支付任何antention。这句话中，而且本身就很难，甚至无法实现，甚至一个细节，诸如衬衫的颜色的选择是一个微妙的说服意味
