原题如下：

（OG20新增）Despite the Puritan sumptuary laws prohibiting the wearing of bright or elaborate clothing, if you had either a liberal education or an annual income of two hundred pounds one was permitted to display their material prosperity in public.

A if you had either a liberal education or annual income of two hundred pounds one was permitted the public display of their material prosperity

B if one had either a liberal education or annual income of two hundred pounds one was permitted the public display of their material prosperity

C having either a liberal education or annual income of two hundred pounds would allow one to publicly display their material prosperity

D those with either a liberal education or an annual income of two hundred pounds were allowed to display their material prosperity in public

E those having either a liberal education or annual income of two hundred pounds were permitted their public display of material prosperity

选项A, B, C, E 均有have annual income of...，虽然income可以是可数名词，也可以是不可数名词，但在和have搭配表示一个人的收入时，income用单数形式。例如《朗文》在income的用法中，给出的搭配为：

have an income (also receive an income formal)

We have an income of over $100,000 a year.

也就是说，ABCE四项均在have后少了不定式冠词，这是其错误之处。只有D项没有错误。

have began当然是错误的，完成时态怎么能是have+过去式呢？
