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

[EX Q]: Passage: Identify evidence for electroweak unification. The quarks in a particle are confined, meaning individual quarks cannot be directly observed. Are gluons confined as well? Explain. Answer: directly observed
[EX A]: The quarks in a particle are confined, meaning individual quarks cannot be what?

[EX Q]: Passage: According to the cell theory , all living things are made up of cells, which is the structural unit of living organisms, and living cells always come from other living cells. In fact, each living thing begins life as a single cell. Some living things, such as bacteria, remain single-celled. Other living things, including plants and animals, grow and develop into many cells. Your own body is made up of an amazing 100 trillion cells! But even youlike all other living thingsbegan life as a single cell. Answer: trillions of cells
[EX A]: What is your body made up of?

[EX Q]: Passage: Alpha, beta, and gamma emissions have different abilities to penetrate matter. The relatively large alpha particle is easily stopped by matter (although it may impart a significant amount of energy to the matter it contacts). Beta particles penetrate slightly into matter, perhaps a few centimeters at most. Gamma rays can penetrate deeply into matter and can impart a large amount of energy into the surrounding. Answer: radiation
[EX A]:
Alpha, beta, and gamma emissions are associated with what kind of energy?
