Problem: The problem of the flow of time, as it has been treated in analytic philosophy, owes its beginning to a paper written by J. M. E. McTaggart. In this paper McTaggart proposes two "temporal series". The first series, which means to account for our intuitions about temporal becoming, or the moving Now, is called the A-series. The A-series orders events according to their being in the past, present or future, simpliciter and in comparison to each other. The B-series eliminates all reference to the present, and the associated temporal modalities of past and future, and orders all events by the temporal relations earlier than and later than.
What is McTaggart's second series called?
---
Answer: The B-series


Problem: In the early days of association football, known simply as football or soccer, friendly matches (or "friendlies") were the most common type of match. However, since the development of The Football League in England in 1888, league tournaments became established, in addition to lengthy derby and cup tournaments. By the year 2000, national leagues were established in almost every country throughout the world, as well as local or regional leagues for lower level teams, thus the significance of friendlies has seriously declined since the 19th century.
When did the Football League begin in England?
---
Answer: 1888


Problem: Technologies based upon the polymerase chain reaction (PCR) method will become nearly ubiquitous gold standards of diagnostics of the near future, for several reasons. First, the catalog of infectious agents has grown to the point that virtually all of the significant infectious agents of the human population have been identified. Second, an infectious agent must grow within the human body to cause disease; essentially it must amplify its own nucleic acids in order to cause a disease. This amplification of nucleic acid in infected tissue offers an opportunity to detect the infectious agent by using PCR. Third, the essential tools for directing PCR, primers, are derived from the genomes of infectious agents, and with time those genomes will be known, if they are not already.
What has the catalog of infectious agents grown to the point of?
---
Answer:
virtually all of the significant infectious agents of the human population have been identified
