Question: Answer the following question given this paragraph: In the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number. Atomic numbers increase from left to right and from top to bottom in the table. Q: What is denoted by the number above the chemical symbol of each element in a modern periodic table? A:
OPTIONS:
- metallic number
- atomic weight
- electron count
- atomic number
Answer: atomic number

input with options: Answer the following question given this paragraph: Galaxies can be spiral, elliptical, or irregular. Q: Galaxies can be spiral, elliptical, or which other type? A:
OPTIONS:
- oblong
- simple
- vertical
- irregular
output: irregular

Q: Answer the following question given this paragraph: Ionic compounds are compounds in which positive metal ions and negative nonmetal ions are joined by ionic bonds. In these compounds, the chemical symbol for the positive metal ion is written first, followed by the symbol for the negative nonmetal ion. The video at the following URL gives a fuller explanation of ionic compounds and their formulas: http://www. youtube. com/watch?v=vscoYh6m46M . Q: The chemical symbol of which ion is written first in ionic compounds? A:

OPTIONS:
- negative ion
- good metal ion
- last ion
- positive metal ion

A: positive metal ion

input: OPTIONS:
- brave
- humble
- lucky
- noble Now, answer this question: Answer the following question given this paragraph: Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds. Q: What type of gases are the least reactive of all elements? A:
A:
output: noble

Answer the following question given this paragraph: Polysaccharides A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide (poly- = "many"). The chain may be branched or unbranched, and it may contain different types of monosaccharides. The molecular weight may be 100,000 daltons or more depending on the number of monomers joined. Starch, glycogen, cellulose, and chitin are primary examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of a mixture of amylose and amylopectin (both polymers of glucose). Plants are able to synthesize glucose, and the excess glucose, beyond the plant's immediate energy needs, is stored as starch in different plant parts, including roots and seeds. The starch in the seeds provides food for the embryo as it germinates and can also act as a source of food for humans and animals. The starch that is consumed by humans is broken down by enzymes, such as salivary amylases, into smaller molecules, such as maltose and glucose. The cells can then absorb the glucose. Starch is made up of glucose monomers that are joined by 1-4 or 1-6 glycosidic bonds. The numbers 1-4 and 1-6 refer to the carbon number of the two residues that have joined to form the bond. As illustrated in Figure 3.9, amylose is starch formed by unbranched chains of glucose monomers (only 1-4 linkages), whereas amylopectin is a branched polysaccharide ( 1-6 linkages at the branch points). Q: A long chain of monosaccharides linked by glycosidic bonds is known as what? A:

OPTIONS:
- sulfate
- Fructose
- polymers
- polysaccharide

Answer: polysaccharide

Q: Answer the following question given this paragraph: Sulfuric acid is produced in extremely large quantities in the United States (about 40 million tons/year). This material is manufactured by oxidizing sulfur to form sulfur trioxide. The SO 3 is then dissolved in water to form the sulfuric acid. Most of the sulfuric acid produced is used in fertilizers. This acid is also found in lead-acid car batteries. Q: What is sulfur trioxide dissolved in to form sulfuric acid? A:

OPTIONS:
- silver
- mercury
- lead
- water

A:
water
