Answer: Lydia's answer is correct.
Explanation:
The solution used by Lydia is:
4/5 × 10 = 4 × 1/5 × 10
= 4 × 10/5
= 4 × 2
= 8
The above solution by Lydia is correct.
Given the question, 4/5 × 10, this will be:
= 4/5 × 10/1
Let's multiply the numerator first, this will be: = 4 × 10 = 40
The denominator will be: = 5 × 1 = 5
Therefore, 4/5 × 10/1 = 40/5
Now when we divide 40 by 5, we will get 8. Therefore Lydia is correct.

Answer:
Option (b).
Explanation:
Pulmonary ventilation is the mechanism of respiration in which the oxygen is inhaled in the body and carbon dioxide is exhaled out due to the pressure difference in the lungs and the environment.
The surface tension in the alveoli is decreased by the presence of surfactant. The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly.
Thus, the correct answer is option (b).
