Task: Question Answering
Input (English): Context: If you ' ve hung out with me at all over the past 8 months or so , you know that I ' ve had a hugely annoying problem -- horribly itchy legs . Sometimes , my legs itched so bad that I actually did n't care if I was scratching them into scabs . I recognized the itch as an allergic reaction . This recognition is solely due to the fact that I was given a little shot of something when I was in labor with Ben . 
Question: Why may the narrator have so many marks on their legs ?
Output (English): They have been clawing at them .
