Explanation:

• Question 1: Stars undergo nuclear fusion reactions. During these reactions, electromagnetic radiation (such as light, heat, etc.) is released. Spallation is a different type of nuclear reaction (involving high - energy particles breaking up nuclei) that is not the main process in stars.
• Question 2: Scapula, petula, and fibula are parts of the human body (bones). Nebula is a cloud of dust and gas in space where stars are formed.
• Question 3: Red dwarf stars (not red giant stars) are the most numerous stars in the universe and have long lifespans. Red giant stars are in a later stage of stellar evolution and are not the most numerous.

• Question 1: A. electromagnetic radiation
• Question 2: D. nebula
• Question 3: False
