user: Answer the following question given this paragraph:   Although California is prone to many natural hazards, including volcanic eruptions at Mt. Shasta or Mt. Lassen, and landslides on coastal cliffs, the natural hazard the state is linked with is earthquakes. In this video, the boundaries between three different tectonic plates and the earthquakes that result from their interactions are explored.   Q: What natural disaster is california most linked with?   A:
OPTIONS:
- fires
- volcanoes
- hurricanes
- earthquakes

Answer: earthquakes


Answer the following question given this paragraph:   2. Sedimentary rocks form when sediments are compacted and cemented together ( Figure below ). These sediments may be gravel, sand, silt or clay. Sedimentary rocks often have pieces of other rocks in them. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates.   Q: What kind of rock forms when material such as gravel, sand, silt or clay is compacted and cemented together?   A:
OPTIONS:
- ingenious
- limestone
- craters
- sedimentary

Answer: sedimentary


Answer the following question given this paragraph:   Processes and Patterns of Evolution Natural selection can only take place if there is variation, or differences, among individuals in a population. Importantly, these differences must have some genetic basis; otherwise, the selection will not lead to change in the next generation. This is critical because variation among individuals can be caused by non-genetic reasons such as an individual being taller because of better nutrition rather than different genes. Genetic diversity in a population comes from two main mechanisms: mutation and sexual reproduction. Mutation, a change in DNA, is the ultimate source of new alleles, or new genetic variation in any population. The genetic changes caused by mutation can have one of three outcomes on the phenotype. A mutation affects the phenotype of the organism in a way that gives it reduced fitness—lower likelihood of survival or fewer offspring. A mutation may produce a phenotype with a beneficial effect on fitness. And, many mutations will also have no effect on the fitness of the phenotype; these are called neutral mutations. Mutations may also have a whole range of effect sizes on the fitness of the organism that expresses them in their phenotype, from a small effect to a great effect. Sexual reproduction also leads to genetic diversity: when two parents reproduce, unique combinations of alleles assemble to produce the unique genotypes and thus phenotypes in each of the offspring. A heritable trait that helps the survival and reproduction of an organism in its present environment is called an adaptation. Scientists describe groups of organisms becoming adapted to their environment when a change in the range of genetic variation occurs over time that increases or maintains the “fit” of the population to its environment. The webbed feet of platypuses are an adaptation for swimming. The snow leopards’ thick fur is an adaptation for living in the cold. The cheetahs’ fast speed is an adaptation for catching prey.   Q: Natural selection can only take place if there is variation, or differences, among individuals in a population. importantly, these differences must have some genetic basis; otherwise, the selection will not lead to change in this?   A:
OPTIONS:
- fertilization
- spontaneous mutation
- mass extinction
- next generation

Answer:

assistant: next generation
