He did n't even know how badly he was hurt . I must have looked so scared for him that it convinced him to go to the hospital . I think we got a B on the project , thanks to the twins who made some order out of Carl 's crap code . So I like to think that this intermittent error in Word was caused by my teammate Carl , the speed junkie .

Question: Why did Carl make an error to the code ?
Answer: Because he works too fast .Because he did what the twins told him to .Because he is inexperienced .None of the above choices .
