The 3Rs by Russell and Burch are known to be the "alternative methods" to improve the treatment of laboratory animals, at the same time to advance the quality of science that uses animals for studies.

Reduction is for reducing the number of animals being used, and using healthier animals. Replacement is using alternative to animals such as tissue cultures and computer models.

intranet is the correct filling
What is intranet
An intranet is a computer network used exclusively by employees of a company for information exchange, improved communication, teamwork tools, operational systems, and other computing services. Although most of the technology is based on the Internet protocol suite, the word is used in contrast to open networks like the Internet.
A company-wide intranet can serve as a key hub for internal communication and teamwork and serve as a single point of access for both internal and external information. The technologies for local area networks (LANs) and wide area networks are used to create an intranet in its most basic form (WANs). The infrastructure of many contemporary intranets includes search engines, user profiles, blogs, mobile apps with notifications, and event organizing.
An extranet and an intranet are occasionally contrasted. Extranets allow customers, suppliers, and other authorized parties access while intranets are typically only accessible by company personnel. Extranets are private networks that are extended onto the Internet with unique authentication, authorization, and accounting features (AAA protocol).
