Jorge is conducting a clinical trial to study the effects of a new medicine on participants. which is an observation jorge might make? jorge wonders if the drug might react with food that participants ate that morning. jorge notices that one of the participants is starting to get a rash on his face. jorge concludes that some participants might get a rash due to their eating habits. jorge advises participants not to eat eggs on the morning of the clinical trial.

An observation is, simply put, a perception of something (or someone). Choice 2 makes the most sense, because Jorge "notices" one of the participants starting to get a rash on his face. Hope this helps!

Option 2, Jorge notices that one of the participants is starting to get a rash on his face

Explanation:

An observation in an experiment is the simple act of noticing the subject (on which experiment is being conducted) or recording the impact of an experiment on the subject  at the primary level of the experiment.

Here in this clinical trial, Jorge is studying the effect of a new medicine on the participants and thus visualizes that one of the participants has got rashes on his face after the ingestion of the new medicine.

Thus, option 2 can be considered as an act of observation and thus it is the right answer.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
