Given a scientific passage and an answer, generate a question for the given answer.

Example Input: Passage: As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a continental arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ). Answer: melts
Example Output: The subducting oceanic plate does what as it reenters the mantle?

Example Input: Passage: The Gaia hypothesis states that the biosphere is its own living organism. Answer: the gaia hypothesis
Example Output: What hypothesis states that the biosphere is its own living organism

Example Input: Passage: Cartilage Cartilage is a connective tissue with a large amount of the matrix and variable amounts of fibers. The cells, called chondrocytes, make the matrix and fibers of the tissue. Chondrocytes are found in spaces within the tissue called lacunae. A cartilage with few collagen and elastic fibers is hyaline cartilage, illustrated in Figure 33.14. The lacunae are randomly scattered throughout the tissue and the matrix takes on a milky or scrubbed appearance with routine histological stains. Sharks have cartilaginous skeletons, as does nearly the entire human skeleton during a specific pre-birth developmental stage. A remnant of this cartilage persists in the outer portion of the human nose. Hyaline cartilage is also found at the ends of long bones, reducing friction and cushioning the articulations of these bones. Answer: cartilage
Example Output:
Like sharks, nearly the entire human skeleton during a specific pre-birth developmental stage is made of what connective tissue?
