The problem: Answer a question about this article:
In 1816, François Magendie discovered that dogs fed only carbohydrates (sugar), fat (olive oil), and water died evidently of starvation, but dogs also fed protein survived, identifying protein as an essential dietary component. William Prout in 1827 was the first person to divide foods into carbohydrates, fat, and protein. During the 19th century, Jean-Baptiste Dumas and Justus von Liebig quarrelled over their shared belief that animals get their protein directly from plants (animal and plant protein are the same and that humans do not create organic compounds). With a reputation as the leading organic chemist of his day but with no credentials in animal physiology, Liebig grew rich making food extracts like beef bouillon and infant formula that were later found to be of questionable nutritious value. In the 1860s, Claude Bernard discovered that body fat can be synthesized from carbohydrate and protein, showing that the energy in blood glucose can be stored as fat or as glycogen.
What can be synthesized using carbohydrates and proteins?
****
The answer: body fat


Problem: Please answer a question about the following article about On the Origin of Species:
The final chapter reviews points from earlier chapters, and Darwin concludes by hoping that his theory might produce revolutionary changes in many fields of natural history. Although he avoids the controversial topic of human origins in the rest of the book so as not to prejudice readers against his theory, here he ventures a cautious hint that psychology would be put on a new foundation and that "Light will be thrown on the origin of man". Darwin ends with a passage that became well known and much quoted:
Why did Darwin avoid the topic of the origins of humans in most of his book?
A: so as not to prejudice readers against his theory

Genetic history of indigenous peoples of the Americas primarily focus on Human Y-chromosome DNA haplogroups and Human mitochondrial DNA haplogroups. "Y-DNA" is passed solely along the patrilineal line, from father to son, while "mtDNA" is passed down the matrilineal line, from mother to offspring of both sexes. Neither recombines, and thus Y-DNA and mtDNA change only by chance mutation at each generation with no intermixture between parents' genetic material. Autosomal "atDNA" markers are also used, but differ from mtDNA or Y-DNA in that they overlap significantly. AtDNA is generally used to measure the average continent-of-ancestry genetic admixture in the entire human genome and related isolated populations.

What does the genetic history of indigenous peoples of the Americas primarily focus on?
Answer: Human Y-chromosome DNA haplogroups


Problem: Citing a 2008 study, the U.S. Center for Disease Control estimated in 2015 that 4.5 million people in the USA are bitten by dogs each year. A 2015 study estimated that 1.8% of the U.S. population is bitten each year. In the 1980s and 1990s the US averaged 17 fatalities per year, while in the 2000s this has increased to 26. 77% of dog bites are from the pet of family or friends, and 50% of attacks occur on the property of the dog's legal owner.
In the 2000s, how many people died every year because of dog bites?
The answer is the following: 26


Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.
Why are high-index glasses valued?
for their diamond-like optical properties


Here is a question about this article: Beyoncé's work has influenced numerous artists including Adele, Ariana Grande, Lady Gaga, Bridgit Mendler, Rihanna, Kelly Rowland, Sam Smith, Meghan Trainor, Nicole Scherzinger, Rita Ora, Zendaya, Cheryl Cole, JoJo, Alexis Jordan, Jessica Sanchez, and Azealia Banks. American indie rock band White Rabbits also cited her an inspiration for their third album Milk Famous (2012), friend Gwyneth Paltrow studied Beyoncé at her live concerts while learning to become a musical performer for the 2010 film Country Strong. Nicki Minaj has stated that seeing Beyoncé's Pepsi commercial influenced her decision to appear in the company's 2012 global campaign.
What is the answer to this question: Which friend learned from Beyonce while preparing for the film, "Country Strong?"
****
So...
Gwyneth Paltrow
