Question: Answer the following question given this paragraph: In the course of a chemical reaction between a metal and a nonmetal, electrons are transferred from the metal atoms to the nonmetal atoms. For example, when zinc metal is mixed with sulfur and heated, the compound zinc sulfide is produced. Two valence electrons from each zinc atom are transferred to each sulfur atom. Q: When zinc metal is mixed with sulfur and heated, what is produced? A:
OPTIONS:
- extraction sulfide
- methane sulfide
- iron
- zinc sulfide
Answer: zinc sulfide

input with options: Answer the following question given this paragraph: A warm-air heating system uses thermal energy to heat air. It then forces the warm air through a system of ducts. You can see a diagram of this type of heating system in Figure below . Typically, the air is heated in a furnace that burns natural gas or heating oil. When the air is warm, a fan blows it through the ducts and out through vents that are located in each room. Warm air blowing out of a vent moves across the room, pushing cold air out of the way. The cold air enters an intake vent on the opposite side of the room and returns to the furnace with the help of another fan. In the furnace, the cold air is heated, and the cycle repeats. Q: A warm-air heating system uses what kind of energy to heat air? A:
OPTIONS:
- atmospheric
- nuclear
- cosmic
- thermal
output: thermal

Q: Answer the following question given this paragraph: Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. Q: What organ is divided into the duodenum, the jejunum, and the ileum? A:

OPTIONS:
- large intestine
- kidney
- lung
- small intestine

A: small intestine

input: OPTIONS:
- example strength
- Movement strength
- seawater strength
- acid strength Now, answer this question: Answer the following question given this paragraph: Polyprotic Acids and Bases As you learned in Chapter 4 "Reactions in Aqueous Solution", polyprotic acids such as H2SO4, H3PO4, and H2CO3 contain more than one ionizable proton, and the protons are lost in a stepwise manner. The fully protonated species is always the strongest acid because it is easier to remove a proton from a neutral molecule than from a negatively charged ion. Thus acid strength decreases with the loss of subsequent protons, and, correspondingly, the pKa increases. Consider H2SO4, for example: Figure 16.5. Q: What decreases with the loss of subsequent protons? A:
A:
output: acid strength

Answer the following question given this paragraph: Q: "crossing over" occurs during what phase of mitosis? A:

OPTIONS:
- Prophase ii
- prophase VI
- prophase iii
- prophase i

Answer: prophase i

Q: Answer the following question given this paragraph: The female reproductive system consists of structures that produce eggs and secrete female sex hormones. They also provide a site for fertilization and enable the development and birth of a fetus. Q: What system consists of structures that produce eggs, secrete female sex hormones, and ultimately enable birth of a fetus? A:

OPTIONS:
- male reproductive system
- female uterus system
- female hormone system
- female reproductive system

A:
female reproductive system
