input: OPTIONS:
- stomach
- mouth
- large intestine
- small intestine Now, answer this question: Answer the following question given this paragraph: Chemical digestion occurs when large food molecules are broken down into smaller nutrient molecules. This is a chemical process that begins in the mouth and stomach but occurs mainly in the small intestine. Q: Where does the majority of chemical digestion occur? A:
A:
output: small intestine

Answer the following question given this paragraph: Telomerase and Aging Cells that undergo cell division continue to have their telomeres shortened because most somatic cells do not make telomerase. This essentially means that telomere shortening is associated with aging. With the advent of modern medicine, preventative health care, and healthier lifestyles, the human life span has increased, and there is an increasing demand for people to look younger and have a better quality of life as they grow older. In 2010, scientists found that telomerase can reverse some age-related conditions in mice. This may have potential in [2] regenerative medicine. Telomerase-deficient mice were used in these studies; these mice have tissue atrophy, stem 2. Jaskelioff et al. , "Telomerase reactivation reverses tissue degeneration in aged telomerase-deficient mice," Nature 469 (2011): 102-7. Q: Cells that undergo cell division continue to have their telomeres shortened, thus telomere shortening is associated with what life process? A:

OPTIONS:
- metabolism
- reducing
- reproduction
- aging

Answer: aging

Problem: OPTIONS:
- egg
- development
- growth
- larval
Q: Answer the following question given this paragraph: In some species, the same individual produces both sperm and eggs. But worms mate to exchange sperm, rather than self-fertilizing their own eggs. Fertilized eggs are deposited in a mucous cocoon. Offspring emerge from the cocoon looking like small adults. They grow to adult size without going through a larval stage. Q: Worms grow to adult size without going through what stage? A:
Answer: larval

Problem:OPTIONS:
- placental mammal
- monotreme
- eukaryotic
- marsupial

Answer the following question given this paragraph: All other mammals give birth to live young and belong to one of two different categories, the marsupials and the placental mammals. A marsupial is an animal in which the embryo, which is often called a joey, is born at an immature stage. Development must be completed outside the mother's body. Most female marsupials have an abdominal pouch or skin fold where there are mammary glands. The pouch is a place for completing the development of the baby. Although blind, without fur, and with only partially formed hind legs, the tiny newborns have well developed forelimbs with claws that enable them to climb their way into their mother's pouch where they drink their mother's milk and continue their development. Marsupials include kangaroos, koalas, and opossums. Other marsupials are the wallaby and the Tasmanian Devil. Most marsupials live in Australia and nearby areas. ( Figure below ). Q: What do you call an animal in which the embryo, often termed a joey, is born immature and must complete its development outside the mother's body? A:
****
A: marsupial

Answer the following question given this paragraph: Thermal energy is converted to the kinetic energy of the moving piston inside the cylinder. The moving piston, in turn, can be used to turn a turbine or do other useful work. Q: Inside a cylinder, thermal energy is converted to what type of energy of the moving piston? A:
OPTIONS:
- residual energy
- horsepower
- electrochemical energy
- kinetic energy
kinetic energy
