Which detail from the excerpt best characterizes Hussain as a cruel man? We all turned around to see the master standing in the doorway. His big body filled it. He was dressed for traveling, with a long coat that almost reached his feet and boots covered with red dust. In his left hand he held a sack, and his right hand held the arm of a boy in an iron grip. Hussain headed toward the door. Once there he stopped and pointed his fat finger toward Karim.

explanation:

having a high metabolism at age 13 is not abnormal.   however, if you are concerned, do consult a doctor.   the doctor may identify a correctable issue, and then you'll have your answer.   in the meantime, there are a few steps you might consider.

first, reflect on just how much physical activity (work out and dancing) you are getting relative to your caloric intake.   keep in mind that if you are interested in gaining weight, you must have a higher caloric intake than output.   second, if eating robust healthy meals is not providing enough calories, you'll need to include high caloric, yet healthy, snacks.   i warn against using an over the counter high-calorie supplement (drink or food) until you have consulted a doctor.
