Hmmm... probably the Clark from the second half of Season 1, especially if he's wearing blue jeans and a black top (t-shirt, polo-shirt or shirt, who cares?
).
And my two questions would be:
"Will you marry me?"
"Will you take off that shirt/t-shirt/polo-shirt of yours?"
Naah, seriously, and I'm going to take some liberty with the boundaries that Yvonne has set, here's what I would ask BaTP Clark:
"Are you tempted to give Lois what she seems to want and start a relationship with her as Superman?"
And then I would switch to S2-second-half Clark to ask:
"Why don't you find a way to get Lois alone one evening to tell her how you feel about her?"

(but the first set of two questions stand anyway
)
