I was also counting the equipment.Earlier, around 8:45 PM, while the engineer was fixing equipment, where were you I was moving between the benches and organizing. I was making sure everything was tidy.While you were organizing, did you see anyone else near the DNA equipment No, I was focused on my tasks. I wasn’t looking at anyone else.Activity 8 Finish the reportsREPORT 1Information:What was the scientist doing last night At 8:15 PM, the scientist ___________ (analyze) data. He __________ (sit) at his computer, looking at charts and numbers on the screen.
