input with options: Answer the following question given this paragraph: The lithosphere is made of the rigid, brittle, solid crust and uppermost mantle. Q: Which part of the earth is made of the rigid, brittle, solid crust and uppermost mantle? A:
OPTIONS:
- troposphere
- thermosphere
- atmosphere
- lithosphere
output: lithosphere

input with options: Answer the following question given this paragraph: For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. If a hypothesis cannot be tested by making observations, it is not scientific. Consider this statement:. Q: A hypothesis is scientific only if it can be tested by what? A:
OPTIONS:
- independent variable
- making a conclusion
- carbon dating
- making observations
output: making observations

input with options: Answer the following question given this paragraph: Many samples have a lot of variation in measurements. Variation can be described with a statistic called the range. The range is the total spread of values in a sample. It is calculated by subtracting the smallest value from the largest value. Q: What term is used to describe the total spread of values in a sample? A:
OPTIONS:
- variety
- axis
- scale
- range
output: range

input with options: Answer the following question given this paragraph: 15.3 Flatworms, Nematodes, and Arthropods Flatworms are acoelomate, triploblastic animals. They lack circulatory and respiratory systems, and have a rudimentary excretory system. The digestive system is incomplete in most species. There are four traditional classes of flatworms, the largely free-living turbellarians, the ectoparasitic monogeneans, and the endoparasitic trematodes and cestodes. Trematodes have complex life cycles involving a secondary mollusk host and a primary host in which sexual reproduction takes place. Cestodes, or tapeworms, infect the digestive systems of primary vertebrate hosts. Nematodes are pseudocoelomate members of the clade Ecdysozoa. They have a complete digestive system and a pseudocoelomic body cavity. This phylum includes free-living as well as parasitic organisms. They include dioecious and hermaphroditic species. Nematodes have a poorly developed excretory system. Embryonic development is external and proceeds through larval stages separated by molts. Arthropods represent the most successful phylum of animals on Earth, in terms of number of species as well as the number of individuals. They are characterized by a segmented body and jointed appendages. In the basic body plan, a pair of appendages is present per body segment. Within the phylum, classification is based on mouthparts, number of appendages, and modifications of appendages. Arthropods bear a chitinous exoskeleton. Gills, tracheae, and book lungs facilitate respiration. Embryonic development may include multiple larval stages. Q: What phylum has the highest number of species on earth? A:
OPTIONS:
- lophotrochozoa
- cephalopods
- lichens
- arthropods
output:
arthropods
