Answer the following question given this paragraph: There are six types of quarks . In ordinary matter, virtually all quarks are of the types called up and down quarks. All quarks have mass, and they have an electric charge of either +2/3 or -1/3. For example, up quarks have a charge of +2/3, and down quarks have a charge of -1/3. Quarks also have a different type of charge, called color charge, although it has nothing to do with the colors that we see. Quarks are never found alone but instead always occur in groups of two or three quarks. Q: Quarks also have a different type of charge, called what? A:
OPTIONS:
- contrast charge
- pure charge
- spontaneous charge
- color charge
color charge

Answer the following question given this paragraph: The modern periodic table is based on atomic number. Elements in each period go from metals on the left to metalloids and then nonmetals on the right. Within groups, elements have similar properties. Q: What is the modern periodic table based on? A:
OPTIONS:
- element mass
- metallic number
- element density
- atomic number

Answer: atomic number

Question: Answer the following question given this paragraph: Compared with the molecules of many other substances, molecules of water are strongly attracted to each other. How is this likely to affect the boiling point of water?. Q: Compared with the molecules of many other substances, molecules of water are strongly attracted to what? A:
OPTIONS:
- hydrogen
- helium
- nothing
- each other
Answer: each other

input with options: Answer the following question given this paragraph: Chytridiomycota: The Chytrids The only class in the Phylum Chytridiomycota is the Chytridiomycetes. The chytrids are the simplest and most primitive Eumycota, or true fungi. The evolutionary record shows that the first recognizable chytrids appeared during the late preCambrian period, more than 500 million years ago. Like all fungi, chytrids have chitin in their cell walls, but one group of chytrids has both cellulose and chitin in the cell wall. Most chytrids are unicellular; a few form multicellular organisms and hyphae, which have no septa between cells (coenocytic). They produce gametes and diploid zoospores that swim with the help of a single flagellum. The ecological habitat and cell structure of chytrids have much in common with protists. Chytrids usually live in aquatic environments, although some species live on land. Some species thrive as parasites on plants, insects, or amphibians (Figure 24.10), while others are saprobes. The chytrid species Allomyces is well characterized as an experimental organism. Its reproductive cycle includes both asexual and sexual phases. Allomyces produces diploid or haploid flagellated zoospores in a sporangium. Q: The chytrids the only class in the phylum chytridiomycota is the chytridiomycetes. the chytrids are the simplest and most primitive eumycota, or true this? A:
OPTIONS:
- acids
- proteins
- organisms
- fungi
output: fungi

Q: Answer the following question given this paragraph: Figure 18.19 The shape of the male reproductive organ varies among male damselfly species, and is only compatible with the female of that species. Reproductive organ incompatibility keeps the species reproductively isolated. Q: What keeps various species from mating and reproducing outside their own species? A:

OPTIONS:
- digestive system incompatibility
- brain organ incompatibility
- cancer organ incompatibility
- reproductive organ incompatibility

A: reproductive organ incompatibility

Answer the following question given this paragraph: Most minerals are a combination of metal and other elements. The rocks that are taken from a mine are full of valuable minerals plus rock that isn't valuable. This is called waste rock. The valuable minerals must be separated from the waste rock. One way to do this is with a chemical reaction. Chemicals are added to the ores at very high temperatures. Q: The rocks that are taken from a mine are full of valuable minerals plus rock that isn't valuable. what is this rock called? A:
OPTIONS:
- garbage rock
- compost rock
- empty rock
- waste rock
waste rock
