input with options: Answer the following question given this paragraph: Ceramics A ceramic is any nonmetallic, inorganic solid that is strong enough for use in structural applications. Traditional ceramics, which are based on metal silicates or aluminosilicates, are the materials used to make pottery, china, bricks, and concrete. Modern ceramics contain a much wider range of components and can be classified as either ceramic oxides, which are based on metal oxides such as alumina (Al2O3), zirconia (ZrO2), and beryllia (BeO), or nonoxide ceramics, which are based on metal carbides such as silicon carbide (carborundum, SiC) and tungsten carbide (WC), or nitrides like silicon nitride (Si 3N4) and boron nitride (BN). All modern ceramics are hard, lightweight, and stable at very high temperatures. Unfortunately, however, they are also rather brittle, tending to crack or break under stresses that would cause metals to bend or dent. Thus a major challenge for materials scientists is to take advantage of the desirable properties of ceramics, such as their thermal and oxidative stability, chemical inertness, and toughness, while finding ways to decrease their brittleness to use them in new applications. Few metals can be used in jet engines, for example, because most lose mechanical strength and react with oxygen at the very high operating. Q: What is any nonmetallic, inorganic solid that is strong enough for use in structural applications called? A:
OPTIONS:
- tissue
- metallic
- glass
- ceramic
output: ceramic

Q: Answer the following question given this paragraph: Q: What are the major sites of gibberellin production? A:

OPTIONS:
- flower and fruit
- soil and leaves
- stem and roots
- young roots and leaves

A: young roots and leaves

input: OPTIONS:
- a flammable gas
- a fatty gas
- an inert gas
- a noble gas Now, answer this question: Answer the following question given this paragraph: The elements of the halogen group (Group 17) gain electrons most readily, as can be seen from their large negative electron affinities. This means that more energy is released in the formation of a halide ion than for the anions of any other elements. Considering electron configuration, it is easy to see why. The outer configuration of all halogens is n s 2 n p 5 . The addition of one more electron gives the halide ions the same electron configuration as a noble gas, which we have seen is particularly stable. Q: The addition of electron gives the halide ions the same electron configuration as what gas? A:
A:
output: a noble gas

Answer the following question given this paragraph: Because the nuclei of each H atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). But because the two atoms involved in the covalent bond are both H atoms, each nucleus attracts the electrons by the same amount. Thus the electron pair is equally shared by the two atoms. The equal sharing of electrons in a covalent bond is called a nonpolar covalent bond. Now consider the HF molecule:. Q: Because the nuclei of each h atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). but because the two atoms involved in the covalent bond are both h atoms, each nucleus attracts the electrons by the same amount. thus the electron pair is equally shared by these? A:

OPTIONS:
- four atoms
- one atom
- nine atoms
- two atoms

Answer: two atoms

Problem: OPTIONS:
- yellow
- blue
- red
- white
Q: Answer the following question given this paragraph: Gluons ( g ) are the proposed carrier particles for the strong nuclear force, although they are not directly observed. Like quarks, gluons may be confined to systems having a total color of white. Less is known about gluons than the fact that they are the carriers of the weak and certainly of the electromagnetic force. QCD theory calls for eight gluons, all massless and all spin 1. Six of the gluons carry a color and an anticolor, while two do not carry color, as illustrated in Figure 33.22(a). There is indirect evidence of the existence of gluons in nucleons. When high-energy electrons are scattered from nucleons and evidence of quarks is seen, the momenta of the quarks are smaller than they would be if there were no gluons. That means that the gluons carrying force between quarks also carry some momentum, inferred by the already indirect quark momentum measurements. At any rate, the gluons carry color charge and can change the colors of quarks when exchanged, as seen in Figure 33.22(b). In the figure, a red down quark interacts with a green strange quark by sending it a gluon. That gluon carries red away from the down. Q: Like quarks, gluons may be confined to systems having a total color of what? A:
Answer: white

Answer the following question given this paragraph: In the single fixed pulley, only one rope segment pulls up on the load, so the ideal mechanical advantage is 1. In other words, this type of pulley doesn't increase the force that is applied to it. However, it does change the direction of the force. This allows you to use your weight to pull on one end of the rope and more easily raise the load attached to the other end. Q: What is the ideal mechanical advantage in the single fixed pulley? A:

OPTIONS:
- zero
- 2
- 4
- 1

Answer:
1
