A(n) _____ is intellectual work that is known only to a company and is not based on public informat
a.private property
b.trade secret
c.copyright
d.patent
e.knowledge base
这题选 B.
第一个选项 Private Property 与后文中的 Intellectual Work 不相容.Property 指的是有形或无形的资产,而不完全是 Intellectual Work.
第三个选项 Copyright 也不对.这是一项权利,而不是 work,而且 copyright 也不是 known only to a company 的.
第四个选项 Patent 也不对.理由同 Copyright.
第五个选项的 Knowledge Base 跟 Private/Public 完全没有关系.
回到 B 选项.Trade Secret 是商业秘密,显然既满足 Intellectual Work 也满足 Know only to a company.参看 Trade secret 的定义：
A trade secret is a formula,practice,process,design,instrument,pattern,or compilation of information which is not generally known or reasonably ascertainable,by which a business can obtain an economic advantage over competitors or customers.In some jurisdictions,such secrets are referred to as "confidential information" or "classified information".
