Answer:
Gandalf says he will be sending Bilbo on an adventure.
Step-by-step explanation:
It should be stressed that in the story, Bilbo loved the life he was leading and was not ready for any change or adventure.
As a result of Gandalf lighting off fireworks in Bilbo's meadow and asking for an invitation to tea the following week, Bilbo was not taken aback by Gandalf's first visit. He didn't want to embark on any adventures, thus he was terrified.
Hope this helps! :)
