My father is good at repairing microcomputers.

His body showed a rejection reaction to the transplanted organ.

His single word triggered a chain reaction, and everything changed.

This chemical reaction is very dangerous.

She overreacted to his words.

Nuclear reactions are used for mass production of energy.

I was surprised by his overreaction.

We are advancing computerization to streamline all operations.

We use a supercomputer to perform complex calculations.

The development of quantum computers is said to open a new frontier in science and technology.
