# 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”.
