Q: What does the stable form of sulfur at room temperature contain? Read this paragraph and choose the correct option from the provided answers: Larger amounts of sulfur also come from hydrogen sulfide recovered during the purification of natural gas. Sulfur exists in several allotropic forms. The stable form at room temperature contains eight-membered rings, and so the true formula is S8. However, chemists commonly use S to simplify the coefficients in chemical equations; we will follow this practice in this book. Choices: - six - membered rings - four - membered rings - electron shell - eight-membered rings A:
eight-membered rings

Q: Gravitational force on a large scale dominates interactions between large objects because it is always what? Read this paragraph and choose the correct option from the provided answers: As the example implies, gravitational force is completely negligible on a small scale, where the interactions of individual charged particles are important. On a large scale, such as between the Earth and a person, the reverse is true. Most objects are nearly electrically neutral, and so attractive and repulsive Coulomb forces nearly cancel. Gravitational force on a large scale dominates interactions between large objects because it is always attractive, while Coulomb forces tend to cancel. Choices: - ugly - vulnerable - suitable - attractive A:
attractive

Q: How do most fish reproduce with one another? Read this paragraph and choose the correct option from the provided answers: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization. Choices: - on land - asexually - same sex - sexually A:
sexually

Q: What is a spectrometer able to produce from starlight? Read this paragraph and choose the correct option from the provided answers: A spectrometer produces a spectrum from starlight. Astronomers can learn a lot about a star by studying its spectrum. Choices: - radio waves - exposure - aspect - spectrum A:
spectrum
