GWD-12-Q13顺便问一下and和or

Although energy prices have tripled in the United States over the last two years, research indicates few people to have significantly reduced the amount of driving they do, nor are they making fuel efficiency a priority when shopping for cars.

1. few people to have significantly reduced the amount of driving they do, nor are they making

2. few people having significantly reduced the amount of driving they do or made

3. that there are few people who have significantly reduced the amount of driving they do, nor having made

4. that few people have significantly reduced the amount of driving they do and are not making

5. that few people have significantly reduced the amount of driving they do or made

我记得石林说有not和no才是否定句，并列用or

否则就是肯定句。用and

他还举了一个例子：I have never been to XX, YY and ZZ.

为什么这里用or?

and 要连接两个并列成分的吧，前面句子用的不定式，and 后面的动词也应该用不定式的，不能用分词

这里要用or，表两种可选择的情况，不是说很少人既减少开车，又在买车的时候考虑节油性能。用and就表示两种事情同时做。
