TASK DEFINITION: Given a scientific passage and an answer, generate a question for the given answer.
PROBLEM: Passage: Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their ability to conduct heat and electricity. They are shiny like metals but brittle like nonmetals. All exist as solids at room temperature. Answer: silicon

SOLUTION: What is an example of a metaloid element?

PROBLEM: Passage: The electron cloud of a helium atom contains two electrons, which can normally be expected to be equally distributed spatially around the nucleus. However, at any given moment the electron distribution may be uneven, resulting in an instantaneous dipole. This weak and temporary dipole subsequently influences neighboring helium atoms through electrostatic attraction and repulsion. It induces a dipole on nearby helium atoms (see Figure below ). Answer: an instantaneous dipole

SOLUTION: A weak and temporary dipole that influences nearby atoms through electrostatic attraction and repulsion is known as what?

PROBLEM: Passage: In the Cell Cycle: Cancer (Advanced) concept, cancer is described as developing due to unregulated cell division. That is, cancer is a disease characterized by a population of cells that grow and divide without respect to normal limits. These cancerous cells invade and destroy adjacent tissues, and they may spread throughout the body. The process by which normal cells are transformed into cancer cells is known as carcinogenesis . This process is also known as oncogenesis or tumorigenesis. Oncogenes are mutated genes involved in the development of cancer. Answer: cell division

SOLUTION:
Cancer develops when what process is unregulated?
