QUES: The Chicago Cubs have not won a World Series championship since 1908, and have not appeared in the Fall Classic since 1945, although between their postseason appearance in 1984 and their most recent in 2015, they have made the postseason seven times. 107 seasons is the longest championship drought in all four of the major North American professional sports leagues, which also includes the National Football League (NFL), the National Basketball Association (NBA), and the National Hockey League (NHL). In fact, the Cubs' last World Series title occurred before those other three leagues even existed, and even the Cubs' last World Series appearance predates the founding of the NBA. The much publicized drought was concurrent to championship droughts by the Boston Red Sox and the Chicago White Sox, who both had over 80 years between championships. It is this unfortunate distinction that has led to the club often being known as "The Lovable Losers." The team was one win away from breaking what is often called the "Curse of the Billy Goat" in 1984 and 2003 (Steve Bartman incident), but was unable get the victory that would send it to the World Series.

QUES: Classical immunology ties in with the fields of epidemiology and medicine. It studies the relationship between the body systems, pathogens, and immunity. The earliest written mention of immunity can be traced back to the plague of Athens in 430 BCE. Thucydides noted that people who had recovered from a previous bout of the disease could nurse the sick without contracting the illness a second time. Many other ancient societies have references to this phenomenon, but it was not until the 19th and 20th centuries before the concept developed into scientific theory.

Which Greek historian made that notation?
What is the answer?
ANS: Thucydides
QUES: In 1974, L. Ottens, director of the audio division of Philips, started a small group with the aim to develop an analog optical audio disc with a diameter of 20 cm and a sound quality superior to that of the vinyl record. However, due to the unsatisfactory performance of the analog format, two Philips research engineers recommended a digital format in March 1974. In 1977, Philips then established a laboratory with the mission of creating a digital audio disc. The diameter of Philips's prototype compact disc was set at 11.5 cm, the diagonal of an audio cassette.
