Which of these would be an appropriate topic for a process analysis?

How to make a good impression on a first date.

How mood is affected by weather.

How organic produce compares to non-organic produce.

How dream recall is unreliable.

As for me, the one topic which would be an appropriate one for a process analysis is being shown in the third option from the scale represented above : How organic produce compares to non-organic produce. This is nice example of a topic where you can divide your essay on the many paragraphs which will match with different processes respectively. So, I think this is a suitable topic.

Regards!
