1. How does physical activity impact cholesterol levels?
A. It raises LDL cholesterol and lowers HDL cholesterol
B. It increases total cholesterol and triglycerides
C. It decreases LDL cholesterol and increases HDL cholesterol

2. What is the main difference between type 1 and type 2
diabetes?
A. Type 1 diabetes is caused by a lack of insulin production, while

B. Type 1 diabetes is caused by insulin resistance, while type 2
diabetes is due to a lack of insulin
C. Type 1 diabetes is a lifestyle disease, while type 2 is genetic
D. There is no difference between the two types
Answer: A) Type 1 diabetes is caused by a lack of insulin
production, while type 2 diabetes involves insulin resistance
Rationale: Type 1 diabetes occurs when the pancreas cannot
produce insulin, while type 2 diabetes develops when the body’s
cells become resistant to insulin.
