This question is about choosing the most appropriate pattern to solve a problem. $($Note that the resources page of the module site includes a Problem solving and Python quick reference with descriptions of all the patterns.$)$

You should read through the following scenario and choose the most appropriate pattern to use.

The magnitude of earthquakes is often measured using the numeric Richter scale, which can be described as follows in a simplified manner:

Magnitude

Description

below $4$

minor

$4$ or more, but less than $6$

moderate

$6$ or more, but less than $7$

strong

$7$ or more, but less than $8$

major

$8$ or more

great

You want to design and write a program that given the Richter magnitude $($a positive floating$-$point number$)$ as the input, prints a message as shown below.

Input

Result

$1$

That is a minor earthquake.

$3\mathrm{.}9$

That is a minor earthquake.

$4$

That is a moderate earthquake.

$6$

That is a strong earthquake.
