Answer:
it would be more helpful if we had more context.
Explanation:
this is an opinion question so I'll give you the outline
The myths of Columbus/Bartolome (choose one) is worth keeping because, (say why one would be better to keep). It can also be better because (say why the other one would be bad to keep). I'm conclusion we should keep the myth of (the one you picked) because (your explanation of why you should keep him but I'm different wording).
it would also be very good if you cited details but I dont know how you are being graded.
