the poll began to reveal its slant

[Torsten]

I understand that the following sentence describes a poll that starts with some rather unimportant questions which are followed by the really significant ones. What would be a synonym for 'slant' here:

After some initial straightforward questions, the poll began to reveal its slant.

Thanks,
Torsten
