Question

which observation is the most objective?
the crystals in this image are magical because they appeared out of nowhere and are totally enormous.

the crystals in this image are jagged and white and developed on the green string between the two solution - filled glass jars.
the crystals in this image remind me of the necklace i wore to my best friends birthday party.

Explanation:

An objective observation is based on facts and details that can be directly seen without personal opinions or interpretations. The first option uses words like "magical" which is an opinion. The second option "cool" is also a subjective opinion. The fourth option is a personal association. The third option describes the crystals' appearance (jagged, white) and their location (on the green string between two solution - filled glass jars) which are factual details.

Answer:

The crystals in this image are jagged and white and developed on the green string between the two solution - filled glass jars.
