Question: Answer the following question given this paragraph: Almost all surfaces reflect some of the light that strikes them. The still water of the lake in Figure above reflects almost all of the light that strikes it. The reflected light forms an image of nearby objects. An image is a copy of an object that is formed by reflected or refracted light. Q: A visual "copy" of an object that is formed by reflected or refracted light is called what? A:
OPTIONS:
- mirror
- instance
- photo
- image
Answer: image

input with options: Answer the following question given this paragraph: Q: Soils with higher capacities generally have a larger reserve of what? A:
OPTIONS:
- hydrogen nutrients
- water
- protein
- mineral nutrients
output: mineral nutrients

Q: Answer the following question given this paragraph: rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision. A collision in which the objects stick together is sometimes called a perfectly inelastic collision because it reduces internal kinetic energy more than does any other type of inelastic collision. In fact, such a collision reduces internal kinetic energy to the minimum it can have while still conserving momentum. Perfectly Inelastic Collision A collision in which the objects stick together is sometimes called "perfectly inelastic. Q: A perfectly inelastic collision reduces internal kinetic energy to the minimum it can have while still conserving what? A:

OPTIONS:
- heat
- energy
- elements
- momentum

A: momentum

input: OPTIONS:
- Mendelian systems
- Newton's third law
- gravitational pull
- van der waals interactions Now, answer this question: Answer the following question given this paragraph: any other electron, they become a part of the molecule's electron system.204 This sharing of electrons produces what is known as a covalent bond. Covalent bonds are ~20 to 50 times stronger than van der Waals interactions. What exactly does that mean? Basically, it takes 20 to 50 times more energy to break a covalent bond compared to a van der Waals interaction. While the bonded form of atoms in a molecule is always more stable than the unbounded form, it may not be stable enough to withstand the energy delivered through collisions with neighboring molecules. Different bonds between different atoms in different molecular contexts differ in terms of bond stability; the bond energy refers the energy needed to break a particular bond. A molecule is stable if the bond energies associated with bonded atoms within the molecule are high enough to survive the energy delivered to the molecule through either collisions with neighboring molecules or the absorption of energy (light). When atoms form a covalent bond, their individual van der Waals surfaces merge to produce a new molecular van der Waals surface. There are a number of ways to draw molecules, but the spacefilling or van der Waals surface view is the most realistic (at least for our purposes). While realistic it can also be confusing, since it obscures the underlying molecular structure, that is, how the atoms in the molecule are linked together. This can be seen in this set of representations of the simple molecule 2methylpropane ().205 As molecules become larger, as is the case with many biologically important molecules, it can become impossible to appreciate their underlying organization based on a van der Waals surface representation. Because they form a new stable entity, it is not surprising (perhaps) that the properties of a molecule are quite distinct from, although certainly influenced by, the properties of the atoms from which they are composed. To a first order approximation, a molecule's properties are based on its shape, which is dictated by how...
