There are many ways. Off the top of my head:

- to focus on speed of development you could use a practice or warm-up

> provide each with a practice in another language

> provide a sample solution in pseudocode in both functional and imperative style

- To focus on speed of problem solving you could use topcoder data + research of participants programming language backgrounds.

The important thing is that if the effect is large it's easy to spot. According to some, the difference is an order of magnitude. If that's true, it will be trivial to spot.
