Question

What is the best answer for this question and why? I rarely do eat meat or I rarely eat meat.?

Answer 1

Both are proper English.  Another way of saying it could be "Rarely do I eat meat."

Answer 2

I rarley eat meat

Answer 3

If this is to be a written answer I would use "I rarely eat meat". It is simple and direct. In speaking, the other form might be appropriate depending on how the question was phrased, but it would never be neccessary to add "do".

Answer 4

"I rarely eat meat" sounds more proper. It makes it more exaggerating when you add the "do".

Answer 5

I rarely eat meat is more grammatical.
