What is your reason _ being late this time?

There has been a request _ more blood donors

I think ill health is deifintely related _ poverty

Opportunities for women are small in relation _ men

Who is responsible _ all this mess?

You can stay up late tonight as a reward _ your good behaviour

There has been a rise _ crime over the past year

There is always a risk _ failure but we must try

He is never rude _ his parents
