A pigeon is confronted with two disks, one green, the other red. The bird receives food on a VI 20" schedule when it pecks the green disk, and on a VI 10" schedule when it pecks the red one. You
Predict that the bird will peck .

A) one disk about as often as at the other
B) the green disk almost exclusively
C) the green disk about twice as often as the red disk
D) the red disk about twice as often as the green disk

D. the red disk about twice as often as the green disk

Explanation:

I predict that the bird will peck that the red disk about twice as often as the green disk.

This is because it will take the VI 20" schedule twice of what it will take VI 10" schedule to deliver food to the pigeon.

Also, the pigeon will pick up the behavior that the VI 10" schedule delivers faster when it pecks on the red disk.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
