Don't know the piece so can't be specific. At the same speed, a quaver rest will last longer than a semi-quaver rest. A semiquaver + semiquaver rest = 1 quaver. A quaver (staccato or otherwise) + a quaver rest = a crotchet. However, playing just the one note to demonstrate the point is fairly pointless as both a staccato quaver and a semi-quaver will sound like short notes! They need to be heard in the context of the phrase.
The thing is that the music has a semiquaver - semiquaver rest - quaver rest in one bar, and a staccato quaver - quaver rest in another bar. I probably didn't explain properly the first time! I suppose what I really want to know is how to play the difference between the two. The composer (Villa-Lobos) must have wanted there to be a difference in note length between the two, and I feel I ought to be able to demonstrate it to my pupil.
