Nevertheless, whether and to what degree any of these types of intermediaries have secondary liability is the subject of ongoing litigation. The decentralised structure of peer-to-peer networks, in particular, does not sit easily with existing laws on online intermediaries' liability. The BitTorrent protocol established an entirely decentralised network architecture in order to distribute large files effectively. Recent developments in peer-to-peer technology towards more complex network configurations are said to have been driven by a desire to avoid liability as intermediaries under existing laws.
What are the reasons for more complex network configurations in peer-to-peer software development?
A: to avoid liability as intermediaries

The process of selectio resembles eclectic textual criticism, but applied to a restricted set of hypothetical hyparchetypes. The steps of examinatio and emendatio resemble copy-text editing. In fact, the other techniques can be seen as special cases of stemmatics in which a rigorous family history of the text cannot be determined but only approximated. If it seems that one manuscript is by far the best text, then copy text editing is appropriate, and if it seems that a group of manuscripts are good, then eclecticism on that group would be proper.
What process is best used when only one manuscript is viable?
A: copy text editing

In addition to the use of sound for communication, a wide range of insects have evolved chemical means for communication. These chemicals, termed semiochemicals, are often derived from plant metabolites include those meant to attract, repel and provide other kinds of information. Pheromones, a type of semiochemical, are used for attracting mates of the opposite sex, for aggregating conspecific individuals of both sexes, for deterring other individuals from approaching, to mark a trail, and to trigger aggression in nearby individuals. Allomonea benefit their producer by the effect they have upon the receiver. Kairomones benefit their receiver instead of their producer. Synomones benefit the producer and the receiver. While some chemicals are targeted at individuals of the same species, others are used for communication across species. The use of scents is especially well known to have developed in social insects.:96105
Semiochemicals come from where?
A: plant metabolites

Tyson Research Center is a 2,000-acre (809 ha) field station located west of St. Louis on the Meramec River. Washington University obtained Tyson as surplus property from the federal government in 1963. It is used by the University as a biological field station and research/education center. In 2010 the Living Learning Center was named one of the first two buildings accredited nationwide as a "living building" under the Living Building Challenge, opened to serve as a biological research station and classroom for summer students.
Who previously owned the property where Tyson Research Center is located?
A:
the federal government
