# Basic If Statements (Making Choices)

1. Complete (i.e., copy into your code and them modify) the following `if` statement so that if `age_class` is equal to “sapling” it sets `y <- 10`.

``````age_class = "sapling"
if (){

}
y
``````

2. Complete the following `if` statement so that if `age_class` is equal to “sapling” it sets `y <- 10` and if `age_class` is equal to “seedling” it sets `y <- 5`.

``````age_class = "seedling"
if (){

}
y
``````

3. Complete the following `if` statement so that if `age_class` is equal to “sapling” it sets `y <- 10` and if `age_class` is equal to “seedling” it sets `y <- 5` and if `age_class` is something else then it sets the value of `y <- 0`.

``````age_class = "adult"
if (){

}
y
``````

4. Convert your conditional statement from (3) into a function that takes `age_class` as an argument and returns `y`. Call this function 5 times, once with each of the following values for `age_class`: “sapling”, “seedling”, “adult”, “mature”, “established”.
