Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Q: Context: To understand minerals, we must first understand matter. Matter is the substance that physical objects are made of. The basic unit of matter is an atom. At the center of an atom is its nucleus. Protons are positively charged particles in the nucleus. Also in the nucleus are neutrons with no electrical charge. Orbiting the nucleus are tiny electrons. Electrons are negatively charged. An atom with the same number of protons and electrons is electrically neutral. If the atom has more or less electrons to protons it is called an ion. An ion will have positive charge if it has more protons than electrons. It will have negative charge if it has more electrons than protons. An atom is the smallest unit of a chemical element. That is, an atom has all the properties of that element. All atoms of the same element have the same number of protons. A molecule is the smallest unit of a chemical compound. A compound is a substance made of two or more elements. The elements in a chemical compound are always present in a certain ratio. Water is probably one of the simplest compounds that you know. A water molecule is made of two hydrogen atoms and one oxygen atom (Figure 3.2). All water molecules have the same ratio: two hydrogen atoms to one oxygen atom. A mineral is a solid material that forms by a natural process. A mineral can be made of an element or a compound. It has a specific chemical composition that is different from other minerals. One minerals physical properties differ from others. These properties include crystal structure, hardness, density and color. Each is made of different elements. Each has different physical properties. For example, silver is a soft, shiny metal. Salt is a white, cube- shaped crystal. Diamond is an extremely hard, translucent crystal. Minerals are made by natural processes. The processes that make minerals happen in or on the Earth. For example, when hot lava cools, mineral crystals form. Minerals also precipitate from water. Some minerals grow when rocks are exposed to high pressures and temperatures. Could something like a mineral be made by a process that was not natural? People make gemstones in a laboratory. Synthetic diamond is a common one. But that stone is not a mineral. It was not formed by a natural process. A mineral is an inorganic substance. It was not made by living organisms. Organic substances contain carbon. Some organic substances are proteins, carbohydrates, and oils. Everything else is inorganic. In a few cases, living organisms make inorganic materials. The calcium carbonate shells made by marine animals are inorganic. All minerals have a definite chemical makeup. A few minerals are made of only one kind of element. Silver is a mineral made only of silver atoms. Diamond and graphite are both made only of the element carbon. Minerals that are not pure elements are made of chemical compounds. For example, the mineral quartz is made of the compound silicon dioxide, or SiO2 . This compound has one atom of the element silicon for every two atoms of the element oxygen. Each mineral has its own unique chemical formula. For example, the mineral hematite has two iron atoms for every three oxygen atoms. The mineral magnetite has three iron atoms for every four oxygen atoms. Many minerals have very complex chemical formulas that include several elements. However, even in more complicated compounds, the elements occur in definite ratios. Minerals must be solid. For example, ice and water have the same chemical composition. Ice is a solid, so it is a mineral. Water is a liquid, so it is not a mineral. Some solids are not crystals. Glass, or the rock obsidian, are solid but not crystals. In a crystal, the atoms are arranged in a pattern. This pattern is regular and it repeats. Figure 3.3 shows how the atoms are arranged in halite (table salt). Halite contains atoms of sodium and chlorine in a pattern. Notice that the pattern goes in all three dimensions. The pattern of atoms in all halite is the same. Think about all of the grains of salt that are 
 Question: smallest particle of an element that has all the elements properties

A: atom

Q: Context: Below are Top 10 Scholarly Stars in America in 2011. It's not always about fame and fortune for these celebs - education is a priority in their lives. Find out what scholarly stars have earned degrees and diplomas or are returning to the classroom as you head back to school. No. 10: James Franco James has attended FOUR prestigious universities in his life: UCLA, New York University, Columbia University and Yale University. We hear he's is so serious about school, he missed the Oscar nominations to attend class! No. 9: Natalie Portman Natalie Portman is so Ivy League: she graduated from Harvard University in 2003, thanks to her parents, who she says always made sure she put her studies before her acting. No. 8: Haley Joel Osment When students at NYU heard Haley Joel would be joining them as a freshman in 2006, they chalked the campus' sidewalks with his famous Sixth Sense movie line: "I see dead people." No. 7: Emma Watson Although Emma Watson put her education on hold to wrap up the Harry Potter film series, in July 2011 she announced that she was going back to school at Brown University to complete her degree. No. 6: Dakota and Elle Fanning Celeb sisters Dakota and Elle Fanning are stars on screen and in class. Dakota was her high school's homecoming queen two years in a row while Elle, who still attends middle school, somehow manages to balance her acting career with math tests and gym class. No. 5: Mara Wilson Mara Wilson graduated from NYU in 2009. Mara, who played the adorable Nattie in Mrs. Doubtfire, eventually grew up and headed to New York to attend NYU's Tisch School of the Arts; she graduated in 2009. No. 4: Tyra Banks Tyra Banks is known for being a savvy businesswoman, but even the best could use some formal training. She enrolled in Harvard Business School in 2011 and even went so far as to live in a dorm with her fellow classmates! "We live in dorms," confirmed the TV star. "I have my own room but we share a kitchen, living room and study area. It's mandatory dorms. I freaked out. In the beginning I was like, 'Oh yes, I'm going to Harvard and I'll be at the Four Seasons down the street.' And they were like, 'Girl, you're living in dorms!'" No. 3: Shakira Singer Shakira is resting her hips and giving her brain a workout at UCLA, attending classes on the history of western civilization so she could "learn from the best". No. 2: Steven Spielberg Director Steven skipped getting a formal education to be an unpaid intern at Universal Studios, where he learned his tricks of the _ . But eventually he did go back and earned his film degree in 2002. No. 1: Danica McKellar Danica McKellar is a math whiz. She used to be known for starring as Winnie Cooper in the Wonder Years, but Danica is also a UCLA graduate, math whiz and education advocate who's written three best-selling books encouraging middle-school girls to have confidence and succeed in mathematics. 
 Question: How many stars referred to in the material studied or will go to UCLA?

A: three.
