worth 4.000 points.
a. drive a car
b. stand up straight
c. reach a top shelf

Explanation:

Sub - Question 1 (BMI Calculation)

Step1: Convert height to inches

5 feet is 5 * 12 = 60 inches. Adding 4 inches, total height \( h = 60 + 4=64\) inches.

Step2: Use BMI formula (imperial units: \(BMI=\frac{weight\ (pounds)\times703}{height\ (inches)^2}\))

Weight \(w = 155\) pounds. So \(BMI=\frac{155\times703}{64^2}\)
First, calculate numerator: \(155\times703 = 155\times(700 + 3)=155\times700+155\times3 = 108500+465 = 108965\)
Denominator: \(64^2=4096\)
Then \(BMI=\frac{108965}{4096}\approx26.6\)
BMI ranges: Underweight: < 18.5; Healthy: 18.5 - 24.9; Overweight: 25 - 29.9; Obese: ≥ 30. Since 25 < 26.6 < 29.9, it's Overweight.

An inflexible body affects movements that require flexibility. Reaching a top shelf needs arm and body flexibility, while driving a car and standing up straight are less related to flexibility in the same way.

Answer:

C. Overweight
