Topics that are contemporary.

Explanation:

Hi. From the context of your question, we can see that you are referring to topics used to write a text or start a survey. In this case, among the types of topics presented above, you should not avoid contemporary topics, because they represent current and relevant issues in today's society and can enrich your text or research.

On the other hand, controversial and trivial topics should be avoided because of their irrelevance and low value. In addition, single-source topics should also be avoided as they do not present diverse and rich information.
