Question

What is the best thing to do to prevent the thatched roofs of huts being blown off during strong winds?


A
Open the doors and windows
loader
B
Close all the doors and windows
loader
C
Make holes in the roof
loader
D
Burn wood inside
loader

Solution

The correct option is B Open the doors and windows
The wind blows from a high-pressure region to a low-pressure region. When strong winds blow over a weak thatched roof, it creates low pressure over it and a high pressure inside the hut causing the roof to blow off. Opening the doors and windows is the most suitable option as it reduces the pressure difference and prevents the roof from being blown off.
