Answer the following question given this paragraph: We can see rainbows because they are formed by visible light. Visible light includes all the wavelengths of light that the human eye can detect. It allows us to see objects in the world around us. Without visible light, we would only be able to sense most objects by sound or touch, and we would never see rainbows. Like humans, most other organisms also depend on visible light, either directly or indirectly. Many animals use it to see. All plants use it to make food in the process of photosynthesis. Without the food made by plants, most other organisms could not survive. Q: What helps us see rainbows in the sky? A:

OPTIONS:
- spectral light
- myopia
- prism
- visible light

Answer: visible light

Problem: OPTIONS:
- improve sediment quality
- improve photosynthesis quality
- improve soil texture
- improve soil quality
Q: Answer the following question given this paragraph: Careful farming helps to keep up soil quality each season. One way is to plant different crops each year. Another is to alternate the crops planted in each row of the field. These techniques preserve and replenish soil nutrients. Planting nutrient rich cover crops helps the soil. Planting trees as windbreaks, plowing along contours of a field, or building terraces into steeper slopes all help to hold soil in place ( Figure below ). No-till or low-till farming disturbs the ground as little as possible during planting. Q: What is the purpose of utilizing careful farming practices such as rotating crops or planting nutrient rich crops? A:
Answer: improve soil quality

Answer the following question given this paragraph: Quantities have two parts: the number and the unit. The number tells "how many. " It is important to be able to express numbers properly so that the quantities can be communicated properly. Standard notation is the straightforward expression of a number. Numbers such as 17, 101.5, and 0.00446 are expressed in standard notation. For relatively small numbers, standard notation is fine. However, for very large numbers, such as 306,000,000, or for very small numbers, such as 0.000000419, standard notation can be cumbersome because of the number of zeros needed to place nonzero numbers in the proper position. Q: Quantities have two parts: the number (how many) and what else? A:
****
A: he unit

Answer the following question given this paragraph: Cellular respiration uses oxygen in addition to glucose. It releases carbon dioxide and water as waste products. Cellular respiration actually "burns" glucose for energy. However, it doesn't produce light or intense heat like burning a candle or log. Instead, it releases the energy slowly, in many small steps. The energy is used to form dozens of molecules of ATP. Q: In addition to glucose, what gas is used during cellular respiration? A:
OPTIONS:
- methane
- hydrogen
- nitrogen
- oxygen
oxygen

Answer the following question given this paragraph: Chemical Digestion in the Small Intestine The digestion of proteins and carbohydrates, which partially occurs in the stomach, is completed in the small intestine with the aid of intestinal and pancreatic juices. Lipids arrive in the intestine largely undigested, so much of the focus here is on lipid digestion, which is facilitated by bile and the enzyme pancreatic lipase. Moreover, intestinal juice combines with pancreatic juice to provide a liquid medium that facilitates absorption. The intestine is also where most water is absorbed, via osmosis. The small intestine's absorptive cells also synthesize digestive enzymes and then place them in the plasma membranes of the microvilli. This distinguishes the small intestine from the stomach; that is, enzymatic digestion occurs not only in the lumen, but also on the luminal surfaces of the mucosal cells. For optimal chemical digestion, chyme must be delivered from the stomach slowly and in small amounts. This is because chyme from the stomach is typically hypertonic, and if large quantities were forced all at once into the small intestine, the resulting osmotic water loss from the blood into the intestinal lumen would result in potentially life-threatening low blood volume. In addition, continued digestion requires an upward adjustment of the low pH of stomach chyme, along with rigorous mixing of the chyme with bile and pancreatic juices. Both processes take time, so the pumping action of the pylorus must be carefully controlled to prevent the duodenum from being overwhelmed with chyme. Q: What two types of juices help digestion within the small intestine? A:
OPTIONS:
- chyme and phloem
- amniotic fluid, bile
- bile and lymph
- intestinal and pancreatic

Answer: intestinal and pancreatic

input with options: Answer the following question given this paragraph: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days. Q: Some of the biggest waves occur with what type of storm that forms over the ocean and brings high winds? A:
OPTIONS:
- tropical depression
- tsunami
- tropical storm
- hurricane
output:
hurricane
