Analytical Writing Assessment (AWA) | Should I double enter betwee a paragraph?

Hello, on monday I'm taking the GMAT again. The last couple of sample test I've done I have wondered if I should double enter between paragraphs?

What do I mean with this? Example (1st and 2nd paragraphs of an AWA reply) *don't mind any other mistakes or suggestions you may have here*
OPTION 1 (single space) vs OPTION 2 (Double space)

I lean more towards option 1, but I really don't know if the computer or human checker considers this to assign a grade for the AWA seciton.

Thanks,
...
