Task: Question Answering
Input (English): I was working in the back yard and I cut my finger on a piece of sharp wood.  I then headed back into the house and washed my hand to make sure the wound was clean and free of dirt and infection.  After washing my hands and the wound with hot, soapy water I put some ointment on the cut to help it heal faster and keep infections out.  I reached into the cabinet and opened the band-aid box so I could take a band-aid out.  I realized that this box didn't have the right size so being careful with use my non-cut hand I reached into another cabinet and found the right sized band-aid.  I tore open the package, pealed back the plastic, and put it over the cut making sure I put the band-aid on nice and tight.  Making sure that the band-aid was secure I headed back out into the yard to finish up my work. 
Question: Why did they put on the band aid?
Output (English): because they had a cut
