Q: John is a biologist. Last summer, he was studying the evolution of two different salamander species, species A and species B. Species A salamander was Gold-striped salamander while species B salamander was fire salamander. He found it interesting that they took different approaches to adapt to different habitats. Which species would have smaller habitat, species A or species B?
A: species A

Q: Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. Which wavelengths would be longer, case A or case B?
A: case A

Q: Gary, a high school student, is supposed to be studying two different cells under a microscope during his biology class. Gary doesn't like biology class at all though and can't find the motivation to look at the cells in detail. In his homework where students are supposed to write what they observed, Gary simply wrote down the first thing he saw under the microscope which was that Cell A is larger than cell B. It won't get him a great grade, but Gary is hoping it will at least get him a pass on the assignment. Will Cell A have an easier or harder time transporting materials than cell B?
A: easier

Q: Doctors studied two groups of individuals: group O with people over 65, and group S with people under 65 years old. They published the results in a magazine. Which group had more people that have retired from work?
