Question

I am a 15 years old boy. My sister is 2 years younger to me but is taller than me. How did this happen?

• A. My sister has more efficient growth hormones than me
• B. Initially girls grow faster than boys during adolescence
• C. I will definitely remain shorter than my sister throughout my life
• D. Can't say

Answer 1

The correct option is B

Initially girls grow faster than boys during adolescence

Well, girls get a head start on puberty — and growing taller — because they usually start these changes between the ages of 8 and 13. Most boys, on the other hand, don't begin until between the ages of 9 and 14. So that's why girls are often taller than boys during that time.
