Nasotracheal suctioning remove fluids or mucus collecting in the airways so the patient can breathe. It literally suctions the airways through a tube threaded into the nose, so it is a delicate procedure. The values you mentioned indicate that the patient is experiencing bradycardia (slowed heartbeat) and hypotension (low blood pressure). Bradycardia and hypotension while doing nasotracheal suctioning indicate that the patient is not tolerating the procedure. In that case, stop suctioning right away and remove the catheter; that is the first priority. Then provide supplemental oxygen (on face mask if possible), and call the doctor.
I think the answer is both B and C,because he needs to confirm his findings by repeating his analysis to make sure he didn't do any mistake in the first process but also needs to analyse fossils found in the same area, because he might find evidence of more fossils from the same time,that would support the hypothesis that there was a community there. You need evidence of a community,because by having multiple fossils of the same age,you could prove the one that you found is indeed older.
