Assume that you have the following function which accepts a whole number $($i$.$e$.$ an int$)$ and returns a fun fact about the given number:

number$\_$fact$\_$sentence$($number: int$)->$ str

Part $1$

When we use the term calling a function, we mean we are trying to use the function in a way consistent with the signature. For example, the signature of number$\_$fact$\_$sentence states that it requires a whole number $($i$.$e$.,$ an int$)$ as an input. Which of the following is a correct call to the number$\_$fact$\_$sentence function?

$($a$)$

$24$

$($b$)$

number$\_$fact$\_$sentence$()$

$($c$)$

number$\_$fact$\_$sentence$24$

$($d$)$

number$\_$fact$\_$sentence

$($e$)$

number$\_$fact$\_$sentence$(24)$

Part $2$

Calling a function does not mean that the value it returns is automatically saved. If we want to save the result of a function, we need to assign the value to a variable. Which of the following is the correct way to assign the result of a call to number$\_$fact$\_$sentence to a variable?

$($a$)$

number$\_$fact$\_$sentence$(42)=$ fact$\_42$

$($b$)$

x $=$ number$\_$fact$\_$sentence$(24)$

$($c$)$

fact$\_42=$ number$\_$fact$\_$sentence

$($d$)$

fact$\_42=$ number$\_$fact$\_$sentence$(42)$

Part $3$

Write a line of code that calls number$\_$fact$\_$sentence with the value $16.$ Assign the result of the function call to a variable called mystery$\_$fact.

Part $4$

Write a line of code that calls number$\_$fact$\_$sentence twice $($once with $86$ and once with $42).$ Connect the two sentences with the word "and". Do not worry about capitialization issues. You do not need to assign the result to a variable.
