Removed questions

[factor-fiction]

Does anyone know why three questions asked yesterday in Science have been removed. I remember Vasco, boxtops and I responded to questions on Quartic Equations and a calculus question, and there was a physics type posting which someone said had been cut and paste from somewhere else.
Can anyone shed any light on these
