 Step 1
-You need to call something on `first` before it can be collected
-Currently its type is `char`. Have a look at the methods that are available on that type:
+The variable `first` is a `char`. It needs to be capitalized and added to the
+remaining characters in `c` in order to return the correct `String`.
+The remaining characters in `c` can be viewed as a string slice using the
+`as_str` method.
+The documentation for `char` contains many useful methods.

 Step 2
-First you'll need to turn the Vec into an iterator
-Then you'll need to apply your function unto each item in the vector
-P.s. Don't forget to collect() at the end!
-
+Create an iterator from the slice. Transform the iterated values by applying
+the `capitalize_first` function. Remember to collect the iterator.
 
 Step 3.
-This is very similar to the previous test. The only real change is that you will need to
-alter the type that collect is coerced into. For a bonus you could try doing this with a

+This is surprising similar to the previous solution. Collect is very powerful
+and very general. Rust just needs to know the desired type."""
