The video says, “if you can’t study fish in the sea, set up an aquarium.” essentially, when you can’t conduct a study in the real world, build a model. what are some of the benefits and drawbacks of this idea?

Some of the advantages of this is you get to have more control of the event that transpire as well as being able to study and observe said events closer. a Disadvantage would be that you're not able to the real thing as in what would actually happen naturally for example if you set up an aquarium it may have a negative affect on the fish or the fish may act a different way in the smaller space as it wouldn't be used to it.

Hope this help! :)

Cand d are correct because the rest are just showing your mistakes and you don’t want people who are reading a summary you wrote to see all the mistakes you made.
