Answer the following question given this paragraph: The stomach is a sac-like organ at the end of the esophagus. It has thick muscular walls. The muscles contract and relax. This moves the food around and helps break it into smaller pieces. Mixing the food around with the enzyme pepsin and other chemicals helps digest proteins. Q: What is the sac-like organ at the end of the esophagus? A:
OPTIONS:
- rectum
- larynx
- appendix
- stomach
stomach

Answer the following question given this paragraph: Virtually all living things use glucose for energy, but glucose is just one of many examples of biochemical compounds that are found in most or all living things. In fact the similarity in biochemical compounds between living things provides some of the best evidence for the evolution of species from common ancestors. A classic example is the biochemical compound called cytochrome c. It is found in all living organisms because it performs essential life functions. Only slight variations in the molecule exist between closely related species, as you can see in the Figure below . The molecule is identical in humans and their closest relatives, the chimpanzees. And even between humans and the single-celled tetrahymena (pictured in the Figure below ), the cytochrome c molecule is nearly 50 percent the same. Q: Similarity in biochemicals, like the glucose used by virtually all living things for energy, provides evidence of what? A:
OPTIONS:
- gravity
- variation
- DNA
- evolution

Answer: evolution

Question: Answer the following question given this paragraph: Sexual reproduction involves two parents. It produces offspring that are all genetically unique. It requires the production of haploid gametes. The union of gametes is called fertilization. It results in a diploid zygote. Q: The union of gametes is called? A:
OPTIONS:
- pollination
- migration
- fusion
- fertilization
Answer: fertilization

input with options: Answer the following question given this paragraph: Sometimes people with an allergy get allergy shots. They are injected with tiny amounts of the allergen that triggers the allergic reaction. The shots are repeated at regular intervals, and the amount of allergen that is injected each time gradually increases. How do you think this might help an allergy? Do you think this approach just treats allergy symptoms or might it cure the allergy?. Q: What type of shots do people with allergy get? A:
OPTIONS:
- nasal shots
- booster shots
- flu shots
- allergy shots
output: allergy shots

Q: Answer the following question given this paragraph: Protists are eukaryotes in the Protist Kingdom. Most are single-celled organisms. Protists are thought to be the oldest eukaryotes. They probably evolved when some prokaryotic cells invaded or were engulfed by others. Q: What is thought to be the oldest eukaryotes? A:

OPTIONS:
- amoebas
- prokaryotes
- arthropods
- protists

A: protists

Answer the following question given this paragraph: A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. Burning is an example of a chemical change. Q: What kind of change occurs whenever matter changes into an entirely different substance with different chemical properties? A:
OPTIONS:
- reversible change
- physical change
- carbon change
- chemical change
chemical change
