Given a scientific passage and an answer, generate a question for the given answer.
question:
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
answer:
The subducting oceanic plate does what as it reenters the mantle?

question:
Passage: Pea plants are naturally self-pollinating. In self-pollination , pollen grains from anthers on one plant are transferred to stigmas of flowers on the same plant. Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination. He removed the anthers from the flowers of some of the plants in his experiments. Then he pollinated them by hand with pollen from other parent plants of his choice. When pollen from one plant fertilizes another plant of the same species, it is called cross-pollination . The offspring that result from such a cross are called hybrids. Answer: cross-pollination
answer:
What is it called when pollen from one plant fertilizes another plant of the same species?

question:
Passage: One example is type 1 diabetes . In this disease, the immune system attacks cells of the pancreas. Other examples are multiple sclerosis and rheumatoid arthritis. In multiple sclerosis , the immune system attacks nerve cells. This causes weakness and pain. In rheumatoid arthritis , the immune system attacks the cells of joints. This causes joint damage and pain. Answer: immune system
answer:
What system is involved in diseases that include type 1 diabetes, rheumatoid arthritis and multiple sclerosis?
