Answer the following question given this paragraph: Q: What carries small pollen grains farther than they otherwise would go? A:
OPTIONS:
- humidity
- steam
- birds
- wind

Answer: wind

Question: Answer the following question given this paragraph: f 2 = v w / 2 = v w / 2L = 2 f 1 . Similarly, f 3 = 3 f 1 , and so on. All of these frequencies can be changed by adjusting the tension in the string. The greater the tension, the greater v w is and the higher the frequencies. This observation is familiar to anyone who has ever observed a string instrument being tuned. We will see in later chapters that standing waves are crucial to many resonance phenomena, such as in sounding boxes on string instruments. Q: Stringed instruments can help show the relationship between tension and what in strings? A:
OPTIONS:
- volumes
- temperatures
- lengths
- frequencies
Answer: frequencies

input with options: Answer the following question given this paragraph: Q: What do you call different organs working together? A:
OPTIONS:
- cellular system
- endocrine system
- maturation systems
- organ systems
output: organ systems

Q: Answer the following question given this paragraph: Amides are actually formed by bringing together an amine-containing molecule and a carboxylic acidcontaining molecule. A molecule of H2O is lost, much like when an ester forms:. Q: Amides are actually formed by bringing together an amine-containing molecule and molecule containing what? A:

OPTIONS:
- oxidize acid
- polymer acid
- Fatty acid
- carboxylic acid

A: carboxylic acid

input: OPTIONS:
- appearance
- language
- systems
- adaptations Now, answer this question: Answer the following question given this paragraph: It's rare for a biologist to predict the discovery of a new species. For his prediction, Kavanaugh drew inspiration from Darwin's own 1862 prediction. When Darwin observed an orchid from Madagascar with a foot-long nectar, he predicted that a pollinator would be found with a tongue long enough to reach the nectar inside the orchid's very thin, elongated nectar ''pouch'', though he had never seen such a bird or insect. Darwin's prediction was based on his finding that all species are related to each other and that some of them evolve together, developing similar adaptations . Darwin's prediction came true in 1903, when a moth was discovered in Madagascar with a long, thin proboscis, which it uncurls to reach the nectar in the orchid's nectar. In the process of feeding from the orchid, the moth serves as its pollinator. The moth was given the scientific name Xanthopan morganii praedicta , in honor of Darwin's prediction. Q: Darwin found that, since all species are related to each other and some of them evolve together, so they develop similar what? A:
A:
output: adaptations

Question: Answer the following question given this paragraph: Sometimes two different minerals have the same chemical composition. But they are different minerals because they have different crystal structures. Diamonds are very valuable as gemstones because they are very pretty and very hard. Graphite is the "lead" in pencils. It's not hard at all! Amazingly, both are made just of carbon. Compare the diamond with the pencil lead ( Figure below ). Why are they so different? The carbon atoms in graphite bond to form layers. The bonds between each layer are weak. The carbon sheets can just slip past each other. The carbon atoms in diamonds bond together in all three directions. This strong network makes diamonds very hard. Q: Why are two different minerals considered different though they have the same chemical composition? A:
OPTIONS:
- different linear structures
- different molecular structures
- different rods structures
- different crystal structures
Answer:
different crystal structures
