Read the sentence. When I attended the aquarium’s camp, I had a pleasant time studying nocturnal sea animals like the squirrelfish. Which word should be replaced with a more precise word?

“Pleasant” is a general word that could describe many enjoyable experiences. A more precise word would explain what made the camp enjoyable, such as “educational” or “fascinating.” The other words are already specific: “nocturnal” means active at night, “marine” means related to the sea, and “squirrelfish” names a particular sea animal.
