TASK DEFINITION: Given a scientific passage and an answer, generate a question for the given answer.
PROBLEM: Passage: Pharyngeal slits : Pharyngeal slits are located in the pharynx. The pharynx is the tube that joins the mouth to the digestive and respiratory tracts. Answer: pharynx

SOLUTION: What is the name of the tube that joins the mouth to the digestive and respiratory tracts?

PROBLEM: Passage: Classification of Joints on the Basis of Function The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses. A synarthrosis is a joint that is immovable. This includes sutures, gomphoses, and synchondroses. Amphiarthroses are joints that allow slight movement, including syndesmoses and symphyses. Diarthroses are joints that allow for free movement of the joint, as in synovial joints. Answer: synarthrosis

SOLUTION: What category of joints is immovable?

PROBLEM: Passage: Most flowers carry both stamens and carpels; however, a few species self-pollinate. These are known as "perfect" flowers because they contain both types of sex organs (Figure 14.25. Biochemical and anatomical barriers to self-pollination promote cross-pollination. Self-pollination is a severe form of inbreeding, and can increase the number of genetic defects in offspring. A plant may have perfect flowers, and thus have both genders in each flower; or, it may have imperfect flowers of both kinds on one plant (Figure 14.28). In each case, such species are called monoecious plants, meaning "one house. " Some botanists refer to plants with perfect flowers simply as hermaphroditic. Some plants are dioecious, meaning "two houses," and have male and female flowers ("imperfect flowers") on different plants. In these species, cross-pollination occurs all the time. Answer: self-pollination

SOLUTION:
Most flowers carry both stamens and carpels; however, a few species are capable of what and are nicknamed "perfect" flowers?
