question:  What effects do the Green Flame rocks have?
context: [Transcriber's Note: This etext was produced from Planet Stories Fall 1944. The Spacemen's was a sanctuary, a rest club where in-coming pilots and crewmen could relax before leaving for another voyage. The rule that no females could pass its portals was strictly enforced. There she stood before a frantically gesticulating desk clerk, leaning on her faded green umbrella. Pure fiddle-faddle, that's what they are. If Annabella C. Flowers wrote a novel, and the locale was the desert of Mars, she packed her carpet bag and hopped a liner for Craterville.

When it had subsided, the man continued: "As most of you are familiar with our program, it will be unnecessary to give any advance explanation. I will only say that on this stage are nine visi sets, each tuned to one of the nine planets. At transmitting sets all over these planets listeners will appear and voice questions. For every question missed, the sender will receive a check for one thousand planetoles . The operator of the Earth visi twisted his dials and nodded. Questions from Mars, from Earth, from Saturn flowed in the visi sets. Isolated miners on Jupiter, dancers in swank Plutonian cafes strove to stump the experts. It was outside under the street marquee that a strange incident occurred. Kagors, of course, had an unpleasant history of persecution since the early colonization days of the Red Planet.
