Answer the following question given this paragraph: Amphibians are vertebrates that live part of the time in fresh water and part of the time on land. They were the first vertebrates to evolve four legs and colonize the land. They most likely evolved from lobe-finned fish. Modern amphibians include frogs, toads, salamanders, newts, and caecilians. They are ectotherms, so they have little control over their body temperature. This allows them to be active in warm weather, but they become sluggish when the temperature cools. Q: Frogs are amphibians that live part of the time in fresh water and rest of the time where? A:

OPTIONS:
- underground
- in stagnant water
- in salt water
- on land

Answer: on land

Problem: OPTIONS:
- gravity
- torque
- strain
- stress
Q: Answer the following question given this paragraph: Stress is the force applied to an object. Stresses can be confining, compression, tension, or shear. Q: The force applied to an object is called? A:
Answer: stress

Problem:OPTIONS:
- dna replication
- carbon cycle
- absorption
- photosynthetic

Answer the following question given this paragraph: Magnesium (Mg) and calcium (Ca) are also important macronutrients. The role of calcium is twofold: to regulate nutrient transport, and to support many enzyme functions. Magnesium is important to the photosynthetic process. These minerals, along with the micronutrients, which are described below, also contribute to the plant's ionic balance. In addition to macronutrients, organisms require various elements in small amounts. These micronutrients, or trace elements, are present in very small quantities. They include boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni), silicon (Si), and sodium (Na). Deficiencies in any of these nutrientsparticularly the macronutrientscan adversely affect plant growth (Figure 31.4. Depending on the specific nutrient, a lack can cause stunted growth, slow growth, or chlorosis (yellowing of the leaves). Extreme deficiencies may result in leaves showing signs of cell death. Q: What process is magnesium important to? A:
****
A: photosynthetic

Answer the following question given this paragraph: Figure below shows the mix of energy resources used worldwide in 2006. Fossil fuels still provide most of the world's energy, with oil being the single most commonly used energy resource. Natural gas is used less than the other two fossil fuels, but even natural gas is used more than all renewable energy resources combined. Wind, solar, and geothermal energy contribute the least to global energy use, despite the fact that they are virtually limitless in supply and nonpolluting. Q: Which fuels provide most of the world's energy? A:
OPTIONS:
- coal fuels
- pattern fuels
- artificial fuels
- fossil fuels
fossil fuels

Answer the following question given this paragraph: Skeletal muscle is attached to the bones of the skeleton. It is striated like cardiac muscle because its muscle fibers are arranged in bundles. Contractions of skeletal muscle are voluntary. This means that they are under conscious control. Whether you are doing pushups or pushing a pencil, you are using skeletal muscles. Skeletal muscles are the most common type of muscles in the body. You can read more about them below. Q: Which type of muscle is most common in the human body? A:
OPTIONS:
- digestive
- smooth
- hormonal
- skeletal

Answer: skeletal

input with options: Answer the following question given this paragraph: Health care has been improving over the most recent centuries. Vaccines were developed that could prevent many diseases ( Figure below ). Antibiotics were discovered that could cure most infections caused by bacteria. Together, these two advances saved countless lives. Q: Antibiotics can cure most infections that are caused by what? A:
OPTIONS:
- bacterium
- algae
- bile
- bacteria
output:
bacteria
