Emphasise the importance of the page title on the 'Check answers' pattern

[timpaul]

There's research from the Register to Vote service that suggests some users don't understand that there's an action to perform on the 'Check answers' page, because the button is often below the fold.

Because of this it's really important that the page title tells the user what they need to do. All the examples in this pattern do this, but we should be explicit about this in the guidance as well.
