The first two panels show the smoke test that was conducted when Dr. Burkholder suspected that the cause of Glasgow's neurological damage was due to the toxic aerosols produced by the dinoflagellates. The circulation system was supposed to provide twelve air exchanges in the "hot" room, where the dino was being cultured. The air system should've been pumping the toxic air outside, but the toxic aerosol was being pumped into the "cold room," which was the 'safe' room that Glasgow could use as an office.
The third panel shows depicts Glasgow taking an exam in the doctor's office, when the neurologist was trying to determine the extent of the damage. Glasgow's reading comprehension abilities were affected ( brain damage in the left temporal lobe) and he was unable to identify simple grammatical errors in the amount of time that a normal person would take.
