Answer the following question given this paragraph: Many of the fibers that compose the materials for our clothes are naturally occurring. Silk and cotton are examples of natural fibers. Silk is produced by the silkworm, and cotton is grown as a plant. However, several chemical processes are used to treat silk thread so that it is shrink-resistant and will repel water. Chemical dyes are frequently used to color various fabrics. Cleaning requires special soaps or chemicals used to dry-clean materials. Cotton will grow better if the boll weevil (an insect that kills the plant) is eliminated with the use of specific insecticides. Ironing of cotton is made easier by the use of chemicals that produce a permanent press in the material. Q: Silk and cotton are examples of what type of fibers? A:
OPTIONS:
- mechanical
- artificial
- coral
- natural

Answer: natural

Question: Answer the following question given this paragraph: Weeks 1624 Once the respiratory bronchioles form, further development includes extensive vascularization, or the development of the blood vessels, as well as the formation of alveolar ducts and alveolar precursors. At about week 19, the respiratory bronchioles have formed. In addition, cells lining the respiratory structures begin to differentiate to form type I and type II pneumocytes. Once type II cells have differentiated, they begin to secrete small amounts of pulmonary surfactant. Around week 20, fetal breathing movements may begin. Q: Alveolar ducts and broncioles are developing parts of what organ system? A:
OPTIONS:
- nervous
- immune
- digestive
- respiratory
Answer: respiratory

input with options: Answer the following question given this paragraph: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. Q: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body where? A:
OPTIONS:
- kidneys
- spleen
- bones
- fat
output: fat

Q: Answer the following question given this paragraph: The most common type of mirage is an illusion that light from faraway objects is reflected by a pool of water that is not really there. Mirages are generally observed in deserts, when there is a hot layer of air near the ground. Given that the refractive index of air is lower for air at higher temperatures, explain how mirages can be formed. Q: What term is used to describe an illusion that light from faraway objects is reflected by a pool of water that is not really there? A:

OPTIONS:
- version
- prototype
- Mirror
- mirage

A: mirage

input: OPTIONS:
- evolution
- vegetation
- isolation
- pollination Now, answer this question: Answer the following question given this paragraph: structure in angiosperms consisting of male and female reproductive structures that attracts animal pollinators. Q: Angiosperms possess reproductive structures that attract animals that perform what role? A:
A:
output: pollination

Question: Answer the following question given this paragraph: All musical instruments create sound by causing matter to vibrate. Most musical instruments use resonance to amplify sound waves and make sounds louder. Most musical instruments also have a way of changing the frequency of sound waves, which changes the pitch of the sounds. Q: Changing the frequency of sound waves, will change the _________ of the sound of a musical instrument? A:
OPTIONS:
- velocity
- distance
- direction
- pitch
Answer:
pitch
