tdol, thank you.
I have three questions.
>5- I'd use 'shrinking'
'The pension size is shrinking' means 'they will get less pension'.
Is 'they will get less pension' acceptable?
>6- It's 'don't make full use...'
Is 'they don't make full use of their potential' wrong?
>You can be promoted beyond your ability.
I guess this expression means 'you're required to perform beyond your ability'.
Does 'perform beyond your ability' have any problem?
