MIKE MOSS SAYS: Judy, You wer on the right track, and now you can be sure. The answer would be "D." Anytime you can see a cloud in the sky (assuming there hasn't been some kind of chemical release - we're talking about routine, natural clouds here) some water vapor had to condense in order to form the cloud droplets. On the other hand, the other answers are all possibilities but not certainties when clouds are seen. Not every cloud produces rain or lightning and thunder, and of course we've all seen clouds on warm days and mild days as well as very cold days.
