 # Lawnmower
 
 ## Step 1
-Oops! The Smart Lawnmower isn't too smart right now. It's running over sprinkler heads and causing damage. Let's make it smarter by changing some parts of the code. We'll replace certain blocks with new ones so that the lawnmower first checks for sprinkler heads before it starts cutting the grass.

 # Bird Trouble
 
 ## Step 1
-Now that we've uncovered the secret words, we can tell that the birds are told to pick up the trash, but there's nowhere to put it. Let's update the code by using different instructions so the birds can handle the trash in a better way, like flying it to the dumpster and dropping it there.

 # Smart Doorlock
 
 ## Step 1
-Anyone can see the records of who has been using the doorlocks, which is a big problem for privacy and safety. We should change the code so that only administrators can look at the event logs.
+Anyone can see the records of who has been using the doorlocks, which is a big problem for privacy and safety. You should change the code so that only administrators can look at the event logs.
 
 #### ~ tutorialhint 
 Change the part of the code where it checks what kind of user you are. Only administrators should be allowed to access it.
