Despite the fact that the seeds of certain tropical trees fall mostly around the parent tree, the seeds that land farther from the parent trees of these species have the greatest chance of germinating. One hypothesis is that the effect is caused by rodents eating a larger number of seeds beside the parent tree than seeds in places farther away, but studies have shown that this is not so.

Which of the following, If true, would most help explain the effect described above?

Last month Ann, Bob, Carl, Dave, and Ellen volunteered at a hospital. The number of hours that Carl volunteered was equal to the average (arithmetic mean) number of hours volunteered by the 5 people. If the number of hours that Carl volunteered was also equal to the total number of hours that Ann and Bob volunteered, then the total number of hours that Dave and Ellen volunteered was how many times the number of hours that Carl volunteered?
