There's a table with test tubes labeled "viruses" and a teacher's science quiz. On the floor is a hammer and some nails.
Sabotage each viral experiment - not too hard. Save the day at epilogue 3.
You refuse to bear the consequences of an outbreak. Destroy the test tubes. Then go to page 18.
Finish its reasonable science test. Then check out the results at page 16.
The nails are intriguing - only one eighth the height of the hammer. Put them in your bag and go to epilogue 4.
The tools must have been used to hide a fossil very quickly. Keep searching on epilogue 5.
