這題選 B.
第一個(gè)選項(xiàng) Private Property 與后文中的 Intellectual Work 不相容.Property 指的是有形或無(wú)形的資產(chǎn),而不完全是 Intellectual Work.
第三個(gè)選項(xiàng) Copyright 也不對(duì).這是一項(xiàng)權(quán)利,而不是 work,而且 copyright 也不是 known only to a company 的.
第四個(gè)選項(xiàng) Patent 也不對(duì).理由同 Copyright.
第五個(gè)選項(xiàng)的 Knowledge Base 跟 Private/Public 完全沒(méi)有關(guān)系.
回到 B 選項(xiàng).Trade Secret 是商業(yè)秘密,顯然既滿(mǎn)足 Intellectual Work 也滿(mǎn)足 Know only to a company.參看 Trade secret 的定義：
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".
