Question 19

An average male adolescent is taller and heavier than an average female adolescent.

Research indicates that during the ages of 10 to 14 years, male adolescents typically experience a growth spurt that results in greater height and weight compared to their female counterparts. This trend is largely due to biological differences in growth patterns and hormonal changes.

A) An average female adolescent is taller and heavier than an average male adolescent

This statement is incorrect as it contradicts the established growth patterns observed during the adolescent years. Females generally reach their peak height and weight earlier than males, leading to males being taller and heavier by the time they are 14.

B) An average male adolescent is taller and heavier than an average female adolescent

This statement accurately reflects the physical development trends observed in adolescents. Males typically grow taller and gain more weight during their growth spurts, which usually occur later than those of females, resulting in males being taller and heavier on average.

C) An average male adolescent is taller but not heavier than an average female adolescent

This statement is incorrect as it underestimates the weight of male adolescents. Their increased height is generally accompanied by greater weight due to muscle mass and overall body composition changes during puberty.

D) An average female adolescent is taller but not heavier than an average male adolescent

This statement is also incorrect. While females may be taller at younger ages, by 14, males typically surpass them in both height and weight, making this assertion inaccurate.

Conclusion

The correct answer is definitively B, as it aligns with the documented physical growth patterns of adolescents between the ages of 10 and 14. All other options fail to accurately represent the comparative heights and weights of average male and female adolescents during this developmental stage.
