The three main groups in science are chemistry,biology and physics.
the mammals that is the only thing i know
The three main groups of mammals are monotremes, marsupials, and placental mammals. Monotremes, like the platypus, lay eggs and produce milk but lack nipples. Marsupials, such as kangaroos, give birth to underdeveloped young that continue to develop in a pouch. In contrast, placental mammals, including humans, have a complex placenta that nourishes the developing fetus during a longer gestation period inside the womb.

No. Marsupials are just one of three groups of mammals. The other two are monotremes and placental mammals. The vast majority of modern mammals are placental.

To narrow it down to three groups, it would be strings, winds, and percussion.
