Input: The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?
"How many protons do atoms contain?" is "Two protons"?

Input: In architecture Durer cites Vitruvius but elaborates his own classical designs and columns. In typography, Durer depicts the geometric construction of the Latin alphabet, relying on Italian precedent. However, his construction of the Gothic alphabet is based upon an entirely different modular system. The fourth book completes the progression of the first and second by moving to three-dimensional forms and the construction of polyhedra. Here Durer discusses the five Platonic solids, as well as seven Archimedean semi-regular solids, as well as several of his own invention. In all these, Durer shows the objects as nets. Finally, Durer discusses the Delian Problem and moves on to the 'construzione legittima', a method of depicting a cube in two dimensions through linear perspective. It was in Bologna that Durer was taught (possibly by Luca Pacioli or Bramante) the principles of linear perspective, and evidently became familiar with the 'costruzione legittima' in a written description of these principles found only, at this time, in the unpublished treatise of Piero della Francesca. He was also familiar with the 'abbreviated construction' as described by Alberti and the geometrical construction of shadows, a technique of Leonardo da Vinci. Although Durer made no innovations in these areas, he is notable as the first Northern European to treat matters of visual representation in a scientific way, and with understanding of Euclidean principles. In addition to these geometrical constructions, Durer discusses in this last book of Underweysung der Messung an assortment of mechanisms for drawing in perspective from models and provides woodcut illustrations of these methods that are often reproduced in discussions of perspective.
"In which book does Durer show the understanding of Euclidean principles?" is "Piero della Francesca"?

Input: (CNN) -- Tito Joseph "TJ" Jackson, who on Wednesday was named temporary guardian of Michael Jackson's three children, was inspired by his famous uncle to form a singing group with his brothers. TJ had been placed in charge of the children when the kids' grandmother, Katherine, left home on July 15 and will watch the children while the legal proceedings play out in a California court. TJ Jackson, 34, is the son of Tito Jackson and the late Delores Martes Jackson. TJ and his older brothers, Taj and Taryll, form the R&B group 3T. Jackson is married with three children, a boy and two girls. Judge suspends Katherine Jackson as guardian of Michael Jackson's children A 1995 article in People described the brothers' childhood as normal despite their famous father, uncle and aunts. Taj Jackson told the magazine: "My mom made sure that we had a real childhood, with birthday parties, baseball, family outings, all that stuff." They were close to their Uncle Michael. "He's like a third parent to us," Taj told People in 1995. Eventually the brothers went along on one of his tours and decided to form a singing group and were recording their first album in 1994 at the time of their mother's death. Initially it was believed Delores Martes Jackson, who had divorced from Tito Jackson in 1993, drowned in a swimming pool, but the case was reopened, and her sons in 1995 filed a wrongful-death lawsuit against a man they accused of killing her. Three years later, Donald Bohana was convicted of second-degree murder and sentenced to 15 years to life in prison, according to People magazine.
"Who is the brother of Tito Jackson?" is "Taryll"?
