Input: Sexual orientation
The American Psychological Association states that "[s]exual orientation refers to an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes" and that "[t]his range of behaviors and attractions has been described in various cultures and nations throughout the world. Many cultures use identity labels to describe people who express these attractions. In the United States, the most frequent labels are lesbians (women attracted to women), gay men (men attracted to men), and bisexual people (men or women attracted to both sexes). However, some people may use different labels or none at all". They additionally state that sexual orientation "is distinct from other components of sex and gender, including biological sex (the anatomical, physiological, and genetic characteristics associated with being male or female), gender identity (the psychological sense of being male or female), and social gender role (the cultural norms that define feminine and masculine behavior)". According to psychologists, sexual orientation also refers to a person's choice of sexual partners, who may be homosexual, heterosexual, or bisexual.

What does the American Physocological Association say that sexual orientation refers to?
Output: an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes

Input: Article: Additionally, genes can have regulatory regions many kilobases upstream or downstream of the open reading frame. These act by binding to transcription factors which then cause the DNA to loop so that the regulatory sequence (and bound transcription factor) become close to the RNA polymerase binding site. For example, enhancers increase transcription by binding an activator protein which then helps to recruit the RNA polymerase to the promoter; conversely silencers bind repressor proteins and make the DNA less available for RNA polymerase.

Now answer this question: What happens when a regulatory region binds to transcription factors?

Output: the DNA to loop

Article: Feynman was a keen popularizer of physics through both books and lectures, including a 1959 talk on top-down nanotechnology called There's Plenty of Room at the Bottom, and the three-volume publication of his undergraduate lectures, The Feynman Lectures on Physics. Feynman also became known through his semi-autobiographical books Surely You're Joking, Mr. Feynman! and What Do You Care What Other People Think? and books written about him, such as Tuva or Bust! and Genius: The Life and Science of Richard Feynman by James Gleick.

Question: What book did James Gleck write about Feynman?
Ans: Genius: The Life and Science of Richard Feynman

Here is a question about this article: Addition of lead(II) oxide lowers melting point, lowers viscosity of the melt, and increases refractive index. Lead oxide also facilitates solubility of other metal oxides and is used in colored glasses. The viscosity decrease of lead glass melt is very significant (roughly 100 times in comparison with soda glasses); this allows easier removal of bubbles and working at lower temperatures, hence its frequent use as an additive in vitreous enamels and glass solders. The high ionic radius of the Pb2+ ion renders it highly immobile in the matrix and hinders the movement of other ions; lead glasses therefore have high electrical resistance, about two orders of magnitude higher than soda-lime glass (108.5 vs 106.5 Ohmcm, DC at 250 C). For more details, see lead glass.
What is the answer to this question: What makes glass melt at a lower temperature?
****
So... lead(II) oxide

The problem: Answer a question about this article:
Evidence of infection in fossil remains is a subject of interest for paleopathologists, scientists who study occurrences of injuries and illness in extinct life forms. Signs of infection have been discovered in the bones of carnivorous dinosaurs. When present, however, these infections seem to tend to be confined to only small regions of the body. A skull attributed to the early carnivorous dinosaur Herrerasaurus ischigualastensis exhibits pit-like wounds surrounded by swollen and porous bone. The unusual texture of the bone around the wounds suggests they were afflicted by a short-lived, non-lethal infection. Scientists who studied the skull speculated that the bite marks were received in a fight with another Herrerasaurus. Other carnivorous dinosaurs with documented evidence of infection include Acrocanthosaurus, Allosaurus, Tyrannosaurus and a tyrannosaur from the Kirtland Formation. The infections from both tyrannosaurs were received by being bitten during a fight, like the Herrerasaurus specimen.
What do paleopathologists study?

The answer: occurrences of injuries and illness in extinct life forms

Another unofficial but much more well-known mascot is Ronnie "Woo Woo" Wickers who is a longtime fan and local celebrity in the Chicago area. He is known to Wrigley Field visitors for his idiosyncratic cheers at baseball games, generally punctuated with an exclamatory "Woo!" (e.g., "Cubs, woo! Cubs, woo! Big-Z, woo! Zambrano, woo! Cubs, woo!") Longtime Cubs announcer Harry Caray dubbed Wickers "Leather Lungs" for his ability to shout for hours at a time. He is not employed by the team, although the club has on two separate occasions allowed him into the broadcast booth and allow him some degree of freedom once he purchases or is given a ticket by fans to get into the games. He is largely allowed to roam the park and interact with fans by Wrigley Field security.
What did Harry Caray dub Wickers?
****
The answer:
"Leather Lungs
