Explanation:
A Fujita scale is a scale that is used to determine the rating for the tornado intensities. It is used to measure the intensity of the tornado and provides a rating based on the damages made by the tornado on the human built structures and other vegetations.
The rating is based on the wind sped and the damages caused by the winds. When the damages caused by a tornado is surveyed, it is compared to the lists of Damage Indicators and the Degree of Damage which helps to estimate the range of the speeds of the tornado and an EF scale rating is provided accordingly.
In the context, It is given that the lightweight roof of a three storied building was uplifted. It was a non residential low rise three story building whose roof was uplifted completely but there was no damages made to the walls of the building.
So according to the EF scale, it provided a rating of :
Damage Indicator Number : 2
Degree of Damage : Moderate
Expected Wind Speed : 73-112 miles per hour
EF-scale Rating : F1

The best soil for gardening is option 2
Explanation:
Loamy soil is the ideal soil for gardening because it is the best for adequate plant growth. A good combination of sand, silt and clay gives the best kind of soil for plant growth. This allows for adequate pores in the soil which is very important for the plant roots and for the passage of water and air into the roots of the plants. The ideal combination for a loamy soil in terms of sand, clay and silt is 40%, 20% and 40% respectively. The best option is the second option which is closest to the ideal loamy soil composition.
