Answer the following question given this paragraph: Wine, air, and gunpowder are other examples of common homogeneous mixtures ( Figure below ). Their exact compositions can vary, making them mixtures rather than pure substances. Wine is a liquid mixture of water, ethanol, and a variety of other dissolved substances. Air is a mixture of nitrogen gas (78%), oxygen gas (21%), and small amounts of various other gases. Gunpowder is a solid mixture comprised of potassium nitrate (75%), charcoal (15%) and sulfur (10%). Q: Wine, air, and gunpowder are all examples of what kind of common mixtures? A:
OPTIONS:
- combined
- contiguous
- heterogeneous
- homogeneous

Answer: homogeneous

Question: Answer the following question given this paragraph: The radiative zone is the next layer out. It has a temperature of about 4 million C. Energy from the core travels through the radiative zone. The energy travels at an extremely slow rate. Light particles are called photons . In the radiative zone, photons can only travel a few millimeters before they hit another particle. The particles are absorbed and then released again. It may take 50 million years for a photon to travel all the way through the radiative zone. Q: In the radiative zone, light particles called what can only travel a few millimeters before they hit another particle? A:
OPTIONS:
- electrons
- positrons
- neutrons
- photons
Answer: photons

input with options: Answer the following question given this paragraph: The cell is the basic unit of life. A cell is made of molecules, which are made of elements. All life-which means all bacteria and archaea, all protists, fungi, plants and animals-is built around the element carbon, and four categories of organic compounds: carbohydrates, lipids, proteins, and nucleic acids. These molecules come together to form a cell, which is the basis of life. One particular type of protein, enzymes, are biological catalysts, allowing biochemical reactions to proceed at the rate necessary to maintain life. One other molecule, water, is also essential to life, though water is not an organic compound. Q: What element is all life built around? A:
OPTIONS:
- hydrogen
- neon
- oxygen
- carbon
output: carbon

Q: Answer the following question given this paragraph: Below the topsoil is the "B" horizon. This is also called the subsoil . Soluble minerals and clays accumulate in the subsoil. Because it has less organic material, this layer is lighter brown in color than topsoil. It also holds more water due to the presence of iron and clay. There is less organic material in this layer. Q: Most waves strike the shore at an angle. this causes what? A:

OPTIONS:
- erosion
- tide
- fontaine drift
- longshore drift

A: longshore drift

Answer the following question given this paragraph: Q: Centipedes have what on their foremost trunk segment, used to paralyze prey and aid in defense? A:
OPTIONS:
- board claws
- animal claws
- diploid claws
- poison claws
poison claws
