Raise your hand first once, and you make it easier for three other people to raise theirs.

Raising your hand in a quiet room is mostly about breaking a stalemate. Everyone is waiting to see whether participating is socially safe, and until somebody tests it, nothing happens and the silence gets heavier. One hand answers the question for the whole room, and three more usually follow within a minute. You are not being keen. You are just removing the risk for everyone else.

Ask the first question next time, even a basic one. Especially a basic one, because at least four other people wanted to ask it and could not go first.
