I have cleaned windows , scrubbed floors and bathrooms and kitchens and all manner of other unsightly things and hoovered lots of small crunchy things that were beginning to stick to the bottom of my socks . I have been a true martyr to the cause . Despite this it appears I have been failing dismally on all counts . Every single meal I have cooked has apparently been inedible shite .

Question: I have been a true martyr to the cause involves what type of cause ?
Answer: None of the above choices .It refers to keeping the children fed at the school .It means volunteering at the janitorial closet charity .It refers to tidying up and keeping things clean at home .
