QUES: As early as 1934, Popper wrote of the search for truth as "one of the strongest motives for scientific discovery." Still, he describes in Objective Knowledge (1972) early concerns about the much-criticised notion of truth as correspondence. Then came the semantic theory of truth formulated by the logician Alfred Tarski and published in 1933. Popper writes of learning in 1935 of the consequences of Tarski's theory, to his intense joy. The theory met critical objections to truth as correspondence and thereby rehabilitated it. The theory also seemed, in Popper's eyes, to support metaphysical realism and the regulative idea of a search for truth.
What did Popper write about before 1934?

QUES: 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 must an infectious agent do to cause disease?

ANS: grow within the human body

QUES: When John DeStefano, Jr., became mayor of New Haven in 1995, he outlined a plan to transform the city into a major cultural and arts center in the Northeast, which involved investments in programs and projects other than sports franchises. As nearby Bridgeport built new sports facilities, the brutalist New Haven Coliseum rapidly deteriorated. Believing the upkeep on the venue to be a drain of tax dollars, the DeStefano administration closed the Coliseum in 2002; it was demolished in 2007. New Haven's last professional sports team, the New Haven County Cutters, left in 2009. The DeStefano administration did, however, see the construction of the New Haven Athletic Center in 1998, a 94,000-square-foot (8,700 m2) indoor athletic facility with a seating capacity of over 3,000. The NHAC, built adjacent to Hillhouse High School, is used for New Haven public schools athletics, as well as large-scale area and state sporting events; it is the largest high school indoor sports complex in the state.
What is the approximate seating capacity of the New Haven Athletic Center?

ANS: over 3,000

QUES: Pain is usually transitory, lasting only until the noxious stimulus is removed or the underlying damage or pathology has healed, but some painful conditions, such as rheumatoid arthritis, peripheral neuropathy, cancer and idiopathic pain, may persist for years. Pain that lasts a long time is called chronic or persistent, and pain that resolves quickly is called acute. Traditionally, the distinction between acute and chronic pain has relied upon an arbitrary interval of time from onset; the two most commonly used markers being 3 months and 6 months since the onset of pain, though some theorists and researchers have placed the transition from acute to chronic pain at 12 months.:93 Others apply acute to pain that lasts less than 30 days, chronic to pain of more than six months' duration, and subacute to pain that lasts from one to six months. A popular alternative definition of chronic pain, involving no arbitrarily fixed durations, is "pain that extends beyond the expected period of healing". Chronic pain may be classified as cancer pain or else as benign.
How many months does acute pain last?
