if a piece of writing moves from one idea to another, it is best to use a
organizational pattern.
a. compare and contrast
b. topical
c. spatial
d. theme

the answer to that would be topical

if you are moving from one thing to another your going to have to make sure that your not jumping around to one thing to another, so you need to keep each paragraph to its own topic and not jumping around all over the place.

HAVE A GREAT DAY
