Which of the following is NOT true about online marketplaces? [br]
In many ways, online marketplaces are the perfect business model. Since they facilitate transactions between independent suppliers and customers rather than take possession of and responsibility for the products or services in question, they have inherently low cost structures and fat gross margins. They are highly defensible once established, owing to network effects.
Your lung capacity in late-middle age is in steady decline, as are the fast-twitch muscle fibers that provide power and speed. Your heart capacity has been ebbing for decades. Your sight has been getting worse, your other senses, too, and this, along with a gradually receding ability to integrate information you are absorbing and to then issue motor commands, means your balance is not what it used to be. Your prefrontal cortex — where the concentrating and deciding gets done — has been shrinking for some time, perhaps since you graduated from college.
选项
A、The older we are, the worse our physical conditions are.
B、The problem of aging has been neglected by the public.
C、The intelligence quality depends on the prefrontal cortex.
D、College education will help people remain young.
答案
A
解析
全文从多个方面阐释人的身体机能随着年龄的增长而慢慢出现退化。prefrontal cogex意为“前额皮质”,是创造力、记忆力、沟通力和自制力等的源头。
