Which one is more coherent?(仅填A或B即可)

AThe most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness.A hollowed-out coconut chained to a stake makes the trap.A monkey can put its hand though a small hole in the coconut and grab some rice inside.The monkey can put its hand into the hole but cannot take its fist out with rice in it.The monkey's value rigidity traps it when it reaches in.The rice cannot be revalued.He cannot see that freedom without rice is more valuable than capture with it.

BThe most striking example of value rigidity I can think of is the old south Indian Monkey Trap, which depends on value rigidity for its effectiveness.The trap consists of a hollowed-out coconut chained to a stake. The coconut has some rice inside which can be grabbed through a small hole.The hole is big enough so that the monkey's hand can go in, but too small for his fist with rice in it to come out.The monkey reaches in and is suddenly trapped - by nothing more than his own value rigidity.He can't revalue the rice.He cannot see that freedom without rice is more valuable than capture with it.
