Question

when someone reads your observations, they should feel...
like they made them themselves.
a sense of confusion.
like a scientist.
like they were present at the time of your observations.

Explanation:

When writing observations, the goal is to vividly convey the scene or situation. If readers feel like they were present during the observations (through detailed descriptions of sights, sounds, etc.), it means the observations are effective. Feeling like they made them (lack of unique perspective), confusion (poor communication), or like a scientist (too technical, not always the goal unless specified) are less ideal.

Answer:

like they were present at the time of your observations.
