Hi, Seagull,
You must have seen polls on this forum usually tdol asks something not too difficult (to choose which is correct) and many people answer. A poll is a survey of opinions.
Frankly speaking, I do not understand the purpose of those polls perhaps tdol is interested in the proficiency of forum visitors or just wants to encourage learners : they can demonsrate they do know English well enough.
As RonBee is undoubtedly a native speaker it was strange to see him asking this kind of question, which led me to the supposition it was sort of a poll.
