The problem: Answer a question about this article:
Symbiotic relationships include those associations in which one organism lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans or Symbiodinium in corals). Symbiosis is also classified by physical attachment of the organisms; symbiosis in which the organisms have bodily union is called conjunctive symbiosis, and symbiosis in which they are not in union is called disjunctive symbiosis.
What is it called when the organisms are not physically joined?
****
The answer: disjunctive symbiosis


Problem: Please answer a question about the following article about Madonna (entertainer):
Madonna starred as Breathless Mahoney in the film Dick Tracy (1990), with Warren Beatty playing the title role. Her performance led to a Saturn Award nomination for Best Actress. To accompany the film, she released the soundtrack album, I'm Breathless, which included songs inspired by the film's 1930s setting. It also featured the US number-one hit "Vogue" and "Sooner or Later", which earned songwriter Stephen Sondheim an Academy Award for Best Original Song in 1991. While shooting the film, Madonna began a relationship with Beatty, which dissolved by the end of 1990. In April 1990, Madonna began her Blond Ambition World Tour, which was held until August. Rolling Stone called it an "elaborately choreographed, sexually provocative extravaganza" and proclaimed it "the best tour of 1990". The tour generated strong negative reaction from religious groups for her performance of "Like a Virgin", during which two male dancers caressed her body before she simulated masturbation. In response, Madonna said, "The tour in no way hurts anybody's sentiments. It's for open minds and gets them to see sexuality in a different way. Their own and others". The Laserdisc release of the tour won Madonna a Grammy Award in 1992 for Best Long Form Music Video.
In the film Dick Tracy, who did Madonna starred as?
A: Breathless Mahoney


Question: Read this and answer the question

In the mid-1950s, Frank Burnet, inspired by a suggestion made by Niels Jerne, formulated the clonal selection theory (CST) of immunity. On the basis of CST, Burnet developed a theory of how an immune response is triggered according to the self/nonself distinction: "self" constituents (constituents of the body) do not trigger destructive immune responses, while "nonself" entities (e.g., pathogens, an allograft) trigger a destructive immune response. The theory was later modified to reflect new discoveries regarding histocompatibility or the complex "two-signal" activation of T cells. The self/nonself theory of immunity and the self/nonself vocabulary have been criticized, but remain very influential.

What property of T cells caused modification of CST?
Answer: the complex "two-signal" activation


Problem: Maximum power transfer requires matching the impedance of an antenna system (as seen looking into the transmission line) to the complex conjugate of the impedance of the receiver or transmitter. In the case of a transmitter, however, the desired matching impedance might not correspond to the dynamic output impedance of the transmitter as analyzed as a source impedance but rather the design value (typically 50 ohms) required for efficient and safe operation of the transmitting circuitry. The intended impedance is normally resistive but a transmitter (and some receivers) may have additional adjustments to cancel a certain amount of reactance in order to "tweak" the match. When a transmission line is used in between the antenna and the transmitter (or receiver) one generally would like an antenna system whose impedance is resistive and near the characteristic impedance of that transmission line in order to minimize the standing wave ratio (SWR) and the increase in transmission line losses it entails, in addition to supplying a good match at the transmitter or receiver itself.
What is the desired design value for transmmiting circuitry?
The answer is the following: 50 ohms


Organized crime has long been associated with New York City, beginning with the Forty Thieves and the Roach Guards in the Five Points in the 1820s. The 20th century saw a rise in the Mafia, dominated by the Five Families, as well as in gangs, including the Black Spades. The Mafia presence has declined in the city in the 21st century.
What was a notable 20th century gang in New York?
the Black Spades


Here is a question about this article: Carnival in the Netherlands is called Carnaval, Vastenavond or Vastelaovend(j), and is most celebrated in traditionally Catholic regions, mainly the southern provinces North Brabant and Limburg. Dutch Carnaval is officially celebrated on the Sunday through Tuesday preceding Ash Wednesday. Although traditions vary from town to town, some common characteristics of Dutch Carnaval include a parade, a "prince" plus cortège ("Jester/adjutant and Council of 11"), a Peasant Wedding (boerenbruiloft), and eating herring (haring happen) on Ash Wednesday.
What is the answer to this question: What vary from town to town in regards to the Carnival?
****
So...
