I know that when something changes (whether it increases or decreases in size, number, or whatever) along with another change, it can be expressed with " the+ comparative, the+ comparative" form. ex) the more, the better / the higher the salary is, the happier the workers get
But I wonder if the ones below are also allowed..
Is it more difficult (Does it get more difficult), the larger the number is?
Do the workers get happier, the higher their salaries are?
