(1). People with a high IQ or educational level showed a higher income
as compared with those with a low IQ or educational level, respectively.
(2). People with a high IQ and educational level showed a higher income
as compared with those with a low IQ and educational level, respectively.
我是要說
high IQ 跟 low IQ 的比起來
以及
high educational level 跟 low educational level 的比起來
income 有差
哪一句比較對？
又 respectively 是不是只能用 or 或是 and 其中之一？意思有差嗎?
Thanks
