nonnative speakers.

and…

To make matters worse, one expression has both! “Make do”
means to manage with what is available. (I couldn’t find any cous cous in the
store, so I had to make do with rice.  I
can’t afford to buy a new car this year, so I’m going to have to make do with
my old Ford for another year.)

Two
idiomatic expressions:

When
you ask someone what they do, you are asking what their job is. (I asked
Anwar what he does and he said he works at Dunkin’ Donuts.)

When
you ask someone what they make or how much they make, you are
asking how much money they earn. (How much do you make at the doughnut shop?)
By the way, it is very rude to ask an American directly how much they make. You
can ask them what they do, but not what they make!
