Answer the following question given this paragraph: Figure 8.15 A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the lightharvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain discussed below. Q: In a photosystem, pigments in the light-harvesting complex pass light energy to two special molecules of what in the reaction center? A:
OPTIONS:
- calcium
- carbonate
- nutrient
- chlorophyll

Answer: chlorophyll

Question: Answer the following question given this paragraph: The sugar of one nucleotide binds to the phosphate group of the next nucleotide. Alternating sugars and phosphate groups form the backbone of a nucleotide chain, as shown in Figure below . The bases, which are bound to the sugars, protrude from the backbone of the chain. In DNA, pairs of bases-one from each of two nucleotides-form the middle section of the molecule. Q: The sugar of one nucleotide binds to what group of the next nucleotide? A:
OPTIONS:
- the alkaline
- the chloride
- the protein
- the phosphate
Answer: the phosphate

input with options: Answer the following question given this paragraph: In some soils, the organic portion is entirely missing. This is true of desert sand. At the other extreme, a soil may be completely organic. Peat, found in a bog or swamp, is totally organic soil. Organic materials are necessary for a soil to be fertile. The organic portion provides the nutrients needed for strong plant growth. Q: Will contour lines ever cross? A:
OPTIONS:
- yes
- in rare cases
- always
- no
output: no

Q: Answer the following question given this paragraph: Skeletal system problems include fractures, osteoarthritis, and rickets. Q: Fractures, osteoarthritis, and rickets are problems of which body system? A:

OPTIONS:
- digestive system
- circulatory system
- cardiovascular system
- skeletal system

A: skeletal system

input: OPTIONS:
- happiness
- weight
- mass
- its temperature Now, answer this question: Answer the following question given this paragraph: Light may be absorbed by matter. This is called absorption of light. When light is absorbed, it doesn't reflect from or pass through matter. Instead, its energy is transferred to particles of matter, which may increase the temperature of matter. Q: When light is absorbed by a material, what may increase? A:
A:
output: its temperature

Question: Answer the following question given this paragraph: Natural gas is often found along with coal or oil in underground deposits. This is because natural gas forms with these other fossil fuels. One difference between natural gas and oil is that natural gas forms at higher temperatures. Q: Natural gas is often found along with what other fossil fuels in underground deposits? A:
OPTIONS:
- methane and oil
- coal and methane
- repository and oil
- coal and oil
Answer:
coal and oil
